They have also been isolated from other organs and tissues such as UMBILICAL CORD BLOOD, umbilical vein subendothelium, and WHARTON JELLY. These cells are considered to be a source of multipotent stem cells because they include subpopulations of mesenchymal stem cells.
Microscopy, Electron, Scanning
Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.
Manufacturing technology for making microscopic devices in the micrometer range (typically 1-100 micrometers), such as integrated circuits or MEMS. The process usually involves replication and parallel fabrication of hundreds or millions of identical structures using various thin film deposition techniques and carried out in environmentally-controlled clean rooms.

Blood Vessel Prosthesis
Mesenchymal Stem Cell Transplantation
Prosthesis, usually heart valve, composed of biological material and whose durability depends upon the stability of the material after pretreatment, rather than regeneration by host cell ingrowth. Durability is achieved 1, mechanically by the interposition of a cloth, usually polytetrafluoroethylene, between the host and the graft, and 2, chemically by stabilization of the tissue by intermolecular linking, usually with glutaraldehyde, after removal of antigenic components, or the use of reconstituted and restructured biopolymers.
Collagen Type II
Guided Tissue Regeneration, Periodontal
Techniques for enhancing and directing cell growth to repopulate specific parts of the PERIODONTIUM that have been damaged by PERIODONTAL DISEASES; TOOTH DISEASES; or TRAUMA, or to correct TOOTH ABNORMALITIES. Repopulation and repair is achieved by guiding the progenitor cells to reproduce in the desired location by blocking contact with surrounding tissue by use of membranes composed of synthetic or natural material that may include growth inducing factors as well.
Prostheses and Implants
Artificial substitutes for body parts, and materials inserted into tissue for functional, cosmetic, or therapeutic purposes. Prostheses can be functional, as in the case of artificial arms and legs, or cosmetic, as in the case of an artificial eye. Implants, all surgically inserted or grafted into the body, tend to be used therapeutically. IMPLANTS, EXPERIMENTAL is available for those used experimentally.
Silicone polymers which consist of silicon atoms substituted with methyl groups and linked by oxygen atoms. They comprise a series of biocompatible materials used as liquids, gels or solids; as film for artificial membranes, gels for implants, and liquids for drug vehicles; and as antifoaming agents.

Microfluidic Analytical Techniques
Intervertebral Disc Degeneration
Extracellular Matrix Proteins
Macromolecular organic compounds that contain carbon, hydrogen, oxygen, nitrogen, and usually, sulfur. These macromolecules (proteins) form an intricate meshwork in which cells are embedded to construct tissues. Variations in the relative types of macromolecules and their organization determine the type of extracellular matrix, each adapted to the functional requirements of the tissue. The two main classes of macromolecules that form the extracellular matrix are: glycosaminoglycans, usually linked to proteins (proteoglycans), and fibrous proteins (e.g., COLLAGEN; ELASTIN; FIBRONECTINS; and LAMININ).
Multipotent Stem Cells

Vitamin K-dependent calcium-binding protein synthesized by OSTEOBLASTS and found primarily in BONES. Serum osteocalcin measurements provide a noninvasive specific marker of bone metabolism. The protein contains three residues of the amino acid gamma-carboxyglutamic acid (Gla), which, in the presence of CALCIUM, promotes binding to HYDROXYAPATITE and subsequent accumulation in BONE MATRIX.
Devices intended to replace non-functioning organs. They may be temporary or permanent. Since they are intended always to function as the natural organs they are replacing, they should be differentiated from PROSTHESES AND IMPLANTS and specific types of prostheses which, though also replacements for body parts, are frequently cosmetic (EYE, ARTIFICIAL) as well as functional (ARTIFICIAL LIMBS).
Induced Pluripotent Stem Cells
Bone Morphogenetic Proteins
Bone-growth regulatory factors that are members of the transforming growth factor-beta superfamily of proteins. They are synthesized as large precursor molecules which are cleaved by proteolytic enzymes. The active form can consist of a dimer of two identical proteins or a heterodimer of two related bone morphogenetic proteins.
Born again bone: tissue engineering for bone repair. (1/3513)Destruction of bone tissue due to disease and inefficient bone healing after traumatic injury may be addressed by tissue engineering techniques. Growth factor, cytokine protein, and gene therapies will be developed, which, in conjunction with suitable carriers, will regenerate missing bone or help in cases of defective healing. (+info)
Engineering virtual cardiac tissue. (2/3513)The kinetics of proteins involved in ion transfer, sequestration and binding in cardiac cells can be modelled to construct a model of the electrical activity of isolated cardiac cells as a system of ordinary differential equations. These cell models may be incorporated into tissue models, which, when combined with histology and anatomy, form virtual tissues. The effects of changes in specific protein expression, or changes in protein kinetics, produced by mutations or pharmacological agents, can be simulated using these tissue models and used to account for the whole organ effects of changes in specific ion-transport protein activity.

Cellular integration of thyrocytes and thyroid folliculogenesis: a perspective for thyroid tissue regeneration and engineering. (3/3513)Thyroid gland is composed of many spheroid structures called thyroid follicles, in which thyrocytes are integrated in their specific structural and functional polarization. In conventional monolayer and floating cultures, the cells cannot reorganize follicle structures with normal polarity. By contrast, in a 3-D collagen gel culture thyrocytes easily and stably reconstruct follicles with physiological polarity. Integration of thyrocyte growth and differentiation appears to result in eventual thyroid folliculogenesis. 3-D collagen gel culture and subacute thyroiditis, a specific thyroid disorder, are the promising models for addressing the mechanism of thyroid folliculogenesis. Because formation of 3-D follicles actively occurs both in this culture system and at the regenerative stage of the disease. The understanding of the mechanistic basis of folliculogenesis is prerequisite for establishment of an artificial thyroid tissue, which would enable a more physiological approach to the treatment of hypothyroidism caused by various diseases and surgical processes than conventional hormone replacement therapy. In this review, we have discussed thyrocyte integration, and thyroid folliculogenesis and tissue regeneration, to further thyroid biology. Also, we briefly discussed a perspective on thyroid tissue regeneration and engineering. (+info)
Oxygen diffusion and consumption of aortic valve cusps. (4/3513)To maintain tissue oxygenation, normal aortic valves contain a vascular bed where tissue thickness is greatest. Avascular "living" tissue-engineered heart valves have been proposed, yet little information exists regarding the magnitude of valve tissue metabolic activity or oxygen requirements. We therefore set out to measure the oxygen diffusivity (DO(2)) and oxygen consumption (VO(2)) of seven porcine aortic valve cusps in vitro at 37 degrees C using a chamber with a Clark oxygen sensor. Mean DO(2) and VO(2) were 1.06 x 10(-5) cm(2)/s and 3.05 x 10(-5) x ml O(2). ml tissue(-1) x s(-1), respectively. When modeled as a three-layered structure by using these values and a boundary condition of 100 mmHg at both surfaces, the average aortic cusp predicted a central mean PO(2) of 27 mmHg (range of 0-50 mmHg). The DO(2) value obtained was similar to that found for other vascular structures, but because our studies were carried out in vitro, the VO(2) measurements may be lower than that required by the functioning valves. These values provide an initial understanding of the oxygen supply possible from the cusp surfaces and the oxygen needs of the tissue. (+info)
Self-assembly and mineralization of peptide-amphiphile nanofibers. (5/3513)We have used the pH-induced self-assembly of a peptide-amphiphile to make a nanostructured fibrous scaffold reminiscent of extracellular matrix. The design of this peptide-amphiphile allows the nanofibers to be reversibly cross-linked to enhance or decrease their structural integrity. After cross-linking, the fibers are able to direct mineralization of hydroxyapatite to form a composite material in which the crystallographic c axes of hydroxyapatite are aligned with the long axes of the fibers. This alignment is the same as that observed between collagen fibrils and hydroxyapatite crystals in bone. (+info)
Contaminants from the transplant contribute to intimal hyperplasia associated with microvascular endothelial cell seeding. (6/3513)OBJECTIVES: seeding prosthetic grafts with fat-derived microvascular endothelial cells (MVEC) results not only in a non-thrombogenic EC layer, but also in intimal hyperplasia. Here we investigated incidence, composition, progression, and cause of this intimal hyperplasia. DESIGN: EPTFE grafts with MVEC were implanted as carotid interpositions in six dogs with 1 month, and in three dogs with 4, 8 and 12 months follow-up. Grafts seeded without cells, implanted in the contralateral carotid, served as a control. In another three dogs labelled cells were seeded to investigate the contribution of the seeded cells (2-3 weeks). MATERIALS AND METHODS: MVEC were isolated from the falciform ligament. Cells were pressure seeded on ePTFE grafts. Labelling was performed using retroviral gene transduction. The grafts were analysed with immunohistochemical techniques. RESULTS: after 1 month, all patent non-seeded grafts (5/6) showed fibrin and platelet deposition, and all patent seeded grafts (5/6) were covered with a confluent endothelial monolayer on top of a multilayer of myofibroblasts, elastin and collagen. After long term follow-up, all non-seeded grafts were occluded, all patent seeded grafts (4 and 12 months) were covered with an EC-layer with intimal hyperplasia underneath. The thickness of the intima did not progress after 1 month. Transduced cells were found in the endothelial monolayer, hyperplastic intima and luminal part of the prosthesis. CONCLUSIONS: MVEC seeding in dogs results in intimal hyperplasia in all patent grafts, which contains myofibroblasts. Contaminants from the transplant contribute to this intimal hyperplasia. (+info)
Replacing and renewing: synthetic materials, biomimetics, and tissue engineering in implant dentistry. (7/3513)Hundreds of thousands of implantations are performed each year in dental clinical practice. Dental implants are a small fraction of the total number of synthetic materials implanted into the human body in all fields of medicine. Basically, these millions of implants going into humans function adequately. But longevity and complications still are significant issues and provide opportunities for the creation of improved devices. This manuscript briefly reviews the history of dental implant devices and the concepts surrounding the word "biocompatibility." It then contrasts the foreign body reaction with normal healing. Finally, the article describes how ideas gleaned from the study of normal wound healing can be applied to improved dental implants. In a concluding section, three scenarios for dental implants twenty years from now are envisioned. (+info)
Expression of renal cell protein markers is dependent on initial mechanical culture conditions. (8/3513)The rotating wall vessel is optimized for suspension culture, with laminar flow and adequate nutrient delivery, but minimal shear. However, higher shears may occur in vivo. During rotating wall vessel cultivation of human renal cells, size and density of glass-coated microcarrier beads were changed to modulate initial shear. Renal-specific proteins were assayed after 2 days. Flow cytometry antibody binding analysis of vitamin D receptor demonstrated peak expression at intermediate shears, with 30% reduction outside this range. Activity of cathepsin C showed the inverse pattern, lowest at midshear, with twofold increases at either extreme. Dipeptidyl-peptidase IV had no shear dependence, suggesting that the other results are specific, not universal, changes in membrane trafficking or protein synthesis. On addition of dextran, which changes medium density and viscosity but not shear, vitamin D receptor assay showed no differences from controls. Neither cell cycle, apoptosis/necrosis indexes, nor lactate dehydrogenase release varied between experiments, confirming that the changes are primary, not secondary to cell cycling or membrane damage. This study provides direct evidence that mechanical culture conditions modulate protein expression in suspension culture. (+info)
Hydrostatic pressure in articular cartilage tissue engineering: From chondrocytes to tissue regeneration<...
TY - JOUR. T1 - Hydrostatic pressure in articular cartilage tissue engineering. T2 - From chondrocytes to tissue regeneration. AU - Elder, Benjamin D.. AU - Athanasiou, Kyriacos A.. PY - 2009/3/1. Y1 - 2009/3/1. N2 - Cartilage has a poor intrinsic healing response, and neither the innate healing response nor current clinical treatments can restore its function. Therefore, articular cartilage tissue engineering is a promising approach for the regeneration of damaged tissue. Because cartilage is exposed to mechanical forces during joint loading, many tissue engineering strategies use exogenous stimuli to enhance the biochemical or biomechanical properties of the engineered tissue. Hydrostatic pressure (HP) is emerging as arguably one of the most important mechanical stimuli for cartilage, although no optimal treatment has been established across all culture systems. Therefore, this review evaluates prior studies on articular cartilage involving the use of HP, with a particular emphasis on the ...

Articular cartilage tissue engineering with plasma-rich in growth factors and stem cells with nano scaffolds | (2016) |...
The ability to heal soft tissue injuries and regenerate cartilage is the Holy Grail of musculoskeletal medicine. Articular cartilage repair and regeneration is considered to be largely intractable due to the poor regenerative properties of this tissue. Due to their low self-repair ability, cartilage defects that result from joint injury, aging, or osteoarthritis, are the most often irreversible and are a major cause of joint pain and chronic disability. However, current methods do not perfectly restore hyaline cartilage and may lead to the apparition of fibro- or continue hypertrophic cartilage. The lack of efficient modalities of treatment has prompted research into tissue engineering combining stem cells, scaffold materials and environmental factors. The field of articular cartilage tissue engineering, which aims to repair, regenerate, and/or improve injured or diseased cartilage functionality, has evoked intense interest and holds great potential for improving cartilage therapy. Plasma-rich ...

Can Tissue Engineering Mend Broken Hearts? | Circulation Research
Cardiac tissue engineering is an emerging field that may hold great promise for advancing the treatment of heart diseases. Cardiac tissue engineering is in its infancy, and the overall field of tissue engineering, which was formalized in the late 1980s at conferences and workshops sponsored by the National Science Foundation, is still new enough to warrant some description. By broad definition, tissue engineering involves the construction of tissue equivalents through the manipulation and combination of living cells and biomaterials. It is a multidisciplinary field combining diverse aspects of the life sciences, engineering, and clinical medicine. The overall goal of tissue engineering is to develop tissue equivalents for use in the repair, replacement, maintenance, or augmentation of tissues or organs. Although some aspects of cardiac tissue engineering research have been ongoing for generations, albeit without being known as such, directed efforts in the field are only beginning.. The main ...
Additive effect of mesenchymal stem cells and VEGF to vascularization of PLGA scaffolds | EnvisionTEC
Bone marrow derived mesenchymal stem cells (bmMSCs) are widely used for the generation of tissue engineering constructs, since they can differentiate into different cell types occurring in bone tissues. Until now their use for the generation of tissue engineering constructs is limited. All cells inside a tissue engineering construct die within a short period of time after implantation of the construct because vascularization and establishment of connections to the recipient circulatory system is a time consuming process. We therefore compared the influences of bmMSC, VEGF and a combination of both on the early processes of vascularization, utilizing the mice skinfold chamber model and intravital fluorescence microscopy.. Tissue engineering constructs based on collagen coated Poly d,l-lactide-co-glycolide (PLGA) scaffolds, were either functionalized by coating with vascular endothelial growth factor (VEGF) or vitalized with bmMSC. PLGA without cells and growth factor was used as the control ...

Long pulse (1 ms) or short pulse (0.25 ms) biphasic electric current at a frequency of 10 Hz was applied to ASCs to study the effects of ES on ASC viability and differentiation towards SMCs on the PPy-coated scaffolds. PPy-coated scaffolds promoted ...
Fundamental Theoretical and Experimental Studies for Applications Toward Functional Tissue Engineering of Articular Cartilage
Theoretical and experimental studies were performed to address the relationships between the microstructure, composition, and mechanical behaviors of articular cartilage and hydrogel-based engineered constructs for functional tissue engineering of articular cartilage. The contributions of the two major components of articular cartilage - negatively charged proteoglycans and bimodular collagen fibrils - to electromechanical properties was described by a triphasic model (Lai, Hou et al, 1991) that is incorporated with conewise linear elasticity constitutive model (Cumier, He et al 1995). The model was solved analytically for the unconfined compression stress relaxation. The fixed charge density of the tissue was successfully quantitatively calculated from stress-relaxation experiments on whole tissue samples. The interaction between collagen and proteoglycans, and the resulting residual stress and curling behaviors of cartilage strips were analyzed with a layeredinhomogeneous, orthotropic, ...
Photopolymerizable scaffolds of native extracellular matrix components for tissue engineering applications
In recent years, significant success has been made in the field of regenerative medicine. Tissue engineering scaffolds have been developed to repair and replace different types of tissues. The overall goal of the current work was to develop scaffolds of native extracellular matrix components for soft tissue regeneration, more specifically, neural tissue engineering. To date, much research has been focused on developing a nerve guidance scaffold for its ability to fill and heal the gap between the damaged nerve ends. Such scaffolds are marked by several intrinsic properties including: (1) a biodegradable scaffold or conduit, consisting of native ECM components, with controlled internal microarchitecture; (2) support cells (such as Schwann cells) embedded in a soft support matrix; and (3) sustained release of bioactive factors. In the current dissertation, we have developed such scaffolds of native biomaterials including hyaluronic acid (HA) and collagen. HA is a nonsulphated, unbranched, ...

A novel injectable temperature-sensitive zinc doped chitosan/β-glycerophosphate hydrogel for bone tissue engineering. - NextBio...
Hydrogels are hydrophilic polymers that have a wide range of biomedical applications including bone tissue engineering. In this study we report preparation and characterization of a thermosensitive hydrogel (Zn-CS/β-GP) containing zinc (Zn), chitosan (CS) and beta-glycerophosphate (β-GP) for bone tissue engineering. The prepared hydrogel exhibited a liquid state at room temperature and turned into a gel at body temperature. The hydrogel was characterized by SEM, EDX, XRD, FT-IR and swelling studies. The hydrogel enhanced antibacterial activity and promoted osteoblast differentiation. Thus, we suggest that the Zn-CS/β-GP hydrogel could have potential impact as an injectable in situ forming scaffold for bone tissue engineering applications. Copyright © 2012 Elsevier B.V.

Characterization and modulation of the immune response in in situ cardiovascular tissue engineering
In situ tissue engineering has become a promising new technique to restore native tissue structure and function by providing a microenvironment necessary to promote tissue regeneration. A biodegradable synthetic starter matrix (scaffold) is introduced to the body to provide this microenvironment at the place of interest. By initiating an inflammatory response upon implantation, a natural wound healing process can be induced to regenerate new tissue. In time, the scaffold will be replaced by this newly formed tissue, resulting in a native, living tissue with growth potential and the capability of remodeling. Within this project, we particularly focus on using in situ tissue engineering to create living heart valves and arteries, as an alternative to the conventional heart valve and small diameter artery replacement therapies, which are accompanied by considerable decrease of life expectancy and therapy-induced complications.

The Use of Dynamic Fluid Flow Strategies for Bone Tissue Engineering Applications
Bone is the second most transplanted tissue in the body, with approximately 2.2 million bone graft procedures performed annually worldwide. Currently, autogenous bone is the gold standard for bone grafting due to its ability to achieve functional healing; however, it is limited in supply and results in secondary injury at the donor site. Tissue engineering has emerged as a promising means for the development of new bone graft substitutes in order to overcome the limitations of the current grafts. In this research project, the specific approach for bone tissue engineering involves seeding osteoprogenitor cells within a biomaterial scaffold then culturing this construct in a biodynamic bioreactor. The bioreactor imparts osteoinductive mechanical stimuli on the cells to stimulate the synthesis of an extracellular matrix rich in osteogenic and angiogenic factors that are envisioned to guide bone healing in vivo. Fluid flow, which exerts a hydrodynamic shear stress on adherent cells, has been ...
Development and Optimization of Imaging and Image Quantification Techn by Ashley Turcott
Blood vessels mimics (BVMs) are tissue-engineered blood vessels used to test vascular devices in an environment that mimics some simple anatomical factors of native blood vessels. It is important to accurately and consistently assess tissue-engineered blood vessels, although there is currently a lack of standardization in Cal Polys Tissue Engineering Lab and in the entirety of the field. The goal of this thesis was to develop and optimize imaging and image quantification techniques for tissue-engineered blood vessels. The first aim of this thesis optimized and compared imaging and assessment techniques for electrospun scaffolds. Images from different SEMs were compared to determine the benefits and drawbacks of each microscope. Several materials were also imaged using these microscopes to characterize polymers at the microscopic scale and to compare the quality of images from different SEMs. The second aim of this thesis validated and implemented a MATLAB-based automatic fiber diameter measurement tool

Principles of cell mechanics for cartilage tissue engineering<...
TY - JOUR. T1 - Principles of cell mechanics for cartilage tissue engineering. AU - Shieh, Adrian C.. AU - Athanasiou, Kyriacos A.. PY - 2003. Y1 - 2003. N2 - The critical importance of mechanical signals to the health and maintenance of articular cartilage has been well demonstrated. Tissue engineers have taken a cue from normal cartilage physiology and incorporated the use of mechanical stimulation into their attempts to engineer functional cartilage. However, the specific types of mechanical stimulation that are most beneficial, and the mechanisms that allow a chondrocyte to perceive and respond to those forces, have yet to be elucidated. To develop a better understanding of these processes, it is necessary to examine the mechanical behavior of the single chondrocyte. This paper reviews salient topics related to chondrocyte biomechanics and mechanotransduction, and attempts to put this information into a context both appropriate and useful to cartilage tissue engineering. It also describes ...
3D Cell Culture Systems for Cardiovascular Tissue Engineering: In Vitro Modelling and In Vivo Regenerative Therapies |...
To date, most in vitro and in vivo studies in the field of cardiovascular tissue research rely on the conventional monolayer (2D) cell cultures. Such 2D culture systems may introduce false positive and/or negative results in the mechanistic studies and translational applications primarily due to the microenvironment of 2D cultures that substantially differ from the in vivo cardiovascular cellular and extracellular matrix (ECM) organizations. Recently, it is found that transition from conventional monolayer cell cultures to 3D culture systems contributes to a closer recapitulation of in vivo features, such as cell heterogeneity, ECM, cell signalling, proliferation, maturation, and response to stimuli. Moreover, recent advances in 3D histotypic and organotypic cultures have escalated the impact and scope in the studies of cardiovascular development, diseases, and therapies. For example, the engineered heart tissue/muscle and cardiovascular spheroids have shown great promises in the in vitro modelling of
Electrospun Natural Proteins for Cardiac Tissue Engineering | [email protected]
Myocardial Infarction leads to end-stage heart failure and it is the major cause of death in many industrialized nations. Tissue engineering approaches for treatment of the infarcted tissue has gained huge attention over the recent years and research in this direction mainly aims for the optimization of a biomaterial scaffold with cell-source for tissue regeneration. In this regard, we fabricated absolutely natural polymeric composite scaffolds, using the blood protein, namely fibrinogen, the denatured collagen glycoprotein gelatin and collagen by electrospinning process. Scaffolds with different weight ratios of fibrinogen:gelatin (Fib:Gel) and Fibrinogen:Collagen (Fib:Coll) was prepared and cross-linking (CL) of the electrospun scaffolds was carried out using glutaraldehyde vapors to improve their mechanical properties. The fiber diameters of the fabricated scaffolds were in the range of 150 ? 300 nm which was close to the size of the native protein fibers in the myocardial extracellular ...

Cartilage Tissue Engineering Using a Modified Decellularized Porcine C by Christopher M. Scanlon
Cartilage tissue engineering remains a top priority due to the limited intrinsic capacity of articular cartilage for self-repair. In this study, the tissue engineering potential of a decellularized porcine cartilage scaffold, in which the proteoglycans (PG) had also been removed, was evaluated. To improve cell distribution within the scaffold, a novel cell seeding technique using centrifugation and a cell seeding device designed for this technique was developed. The modified porcine cartilage scaffolds were seeded with chondrocytes using the novel cell seeding technique and left in static culture for up to 21 days. A previously described bioreactor was used to measure the properties of the constructs at 7, 14, and 21 days. The ability of the scaffolds to support cell viability and proliferation and extracellular matrix deposition was evaluated at these time points as well. The novel cell seeding technique was also evaluated at 24 hours. Results indicated that the scaffold was capable of supporting cell

Nicolas L´Heureux, Todd McAllister, Sergio Garrido, Alicia Marini, Hernan Avila, Luis de la Fuente, Ximena Manglano, Robert C Robbins, Gerhardt Konig, Nathalie Dusserre. The historical challenge in the field of Cardiovascular Tissue Engineering has been to produce a conduit with the appropriate mechanical strength (i.e. burst pressure in excess of 1700 mmHg). To achieve the requisite strength, most approaches have relied upon permanent synthetic or xenogeneic scaffolds. These scaffolds, however, may be associated with chronic inflammation, disease transmission, or mechanical degradation that limit their clinical use. In an effort to eliminate the deleterious effects of permanent biomaterials, more recent trends have focused on either resorbable scaffolds or completely biological approaches. Previously we reported a completely ...
Characterizing the efficacy of calcium channel agonist-release strategies for bone tissue engineering applications. - Nuffield...
We have previously reported on the use of Bay K8644-release strategies in combination with perfusion-compression bioreactor systems for up regulating bone formation in three-dimensional PLLA scaffolds. Here we report on the analysis of Bay activity following its release from our PLLA scaffolds over the culture period imposed in our tissue engineering protocol using UV spectroscopy in combination with whole cell patch clamping techniques. Bay was released continually from scaffolds within the physiological range required for agonist activity (1-10 microM). Patch clamping allowed for the effects of Bay released from scaffolds to be monitored directly with respect to osteoblast electrophysiology. A characteristic shift in the current-voltage (I-V) relationship of L-type VOCC currents was observed in rat osteoblast sarcoma (ROS) cells patched in a solution with Bay released from scaffolds following 14 and 28 days incubation, with statistically significant differences observed in peak currents compared to

Autologous tissue-engineered blood vessels (TEBVs) generated using adult stem cells have shown promising results, but many preclinical evaluations do not test the efficacy of stem cells from patient populations likely to need therapy (i.e., elderly and diabetic humans). Two critical functions of these cells will be (i) secreting factors that induce the migration of host cells into the graft and (ii) differentiating into functional vascular cells themselves. The purpose of this study was to analyze whether adipose-derived mesenchymal stem cells (AD-MSCs) sourced from diabetic and elderly patients have a reduced ability to promote human smooth muscle cell (SMC) migration and differentiation potential toward SMCs, two important processes in stem cell-based tissue engineering of vascular grafts ...

Poly(3-hydroxyoctanoate), a promising new material for cardiac tissue engineering - WestminsterResearch
Cardiac tissue engineering (CTE) is currently a prime focus of research due to an enormous clinical need. In this work, a novel functional material, Poly(3-hydroxyoctanoate), P(3HO), a medium chain length polyhydroxyalkanoate (PHA), produced using bacterial fermentation, was studied as a new potential material for CTE. Engineered constructs with improved mechanical properties, crucial for supporting the organ during new tissue regeneration, and enhanced surface topography, to allow efficient cell adhesion and proliferation, were fabricated. Our results showed that the mechanical properties of the final patches were close to that of cardiac muscle. Biocompatibility of the P(3HO) neat patches, assessed using Neonatal ventricular rat myocytes (NVRM), showed that the polymer was as good as collagen in terms of cell viability, proliferation and adhesion. Enhanced cell adhesion and proliferation properties were observed when porous and fibrous structures were incorporated to the patches. Also, no ...

Pharmaceuticals | Free Full-Text | Tissue Engineering of Cartilage; Can Cannabinoids Help?
This review discusses the role of the cannabinoid system in cartilage tissue and endeavors to establish if targeting the cannabinoid system has potential in mesenchymal stem cell based tissue-engineered cartilage repair strategies. The review discusses the potential of cannabinoids to protect against the degradation of cartilage in inflamed arthritic joints and the influence of cannabinoids on the chondrocyte precursors, mesenchymal stem cells (MSCs). We provide experimental evidence to show that activation of the cannabinoid system enhances the survival, migration and chondrogenic differentiation of MSCs, which are three major tenets behind the success of a cell-based tissue-engineered cartilage repair strategy. These findings highlight the potential for cannabinoids to provide a dual function by acting as anti-inflammatory agents as well as regulators of MSC biology in order to enhance tissue engineering strategies aimed at cartilage repair.
Successful human long-term application of in situ bone tissue engineering - Horch - 2014 - Journal of Cellular and Molecular...
Until now, Tissue Engineering techniques have frequently been shown to be promising in vitro and in vivo in experimental settings, but have widely failed to enter the clinical routine when it comes to large defects or major organ functional replacements . One of the key roles for this insufficient transition into clinical practice has been discussed to be dependent on the lack of sufficient vasculature at the time of transplanting laboratory-grown constructs into relevant and especially into poorly vascularized recipient areas. Large bone defects present a prototype of such difficult to handle clinical replacement problems, as vascularized bone grafts are associated with a significant donor-site morbidity and non-vascularized bone grafts do not heal into problematic sites. The optimal bone graft for any successful reconstruction of a large osseus defect would consist of a custom-designed vascularized bone substitute without creating any donor-site morbidity. Almost all bone tissue ...
Role of MicroRNAs in Human Skeletal Muscle Tissue Engineering In Vitro
The development of a functional tissue-engineered human skeletal muscle model in vitro would provide an excellent platform on which to study the process of myogenesis, various musculoskeletal disease states, and drugs and therapies for muscle toxicity. We developed a protocol to culture human skeletal muscle bundles in a fibrin hydrogel under static conditions capable of exerting active contractions. Additionally, we demonstrated the use of joint miR-133a and miR-696 inhibition for acceleration of muscle differentiation, elevation of active contractile force amplitudes, and increasing Type II myofiber formation in vitro. The global hypothesis that motivated this research was that joint inhibition of miR-133a and miR-696 in isolated primary human skeletal myoblasts would lead to accelerated differentiation of tissue-engineered muscle constructs with higher proportion of Type I myofibers and that are capable of significantly increased active contractile forces when subjected to electrical ...

Nanotechnology Now - News Story: One day doctors will grow new bones with nanotechnology
Nanotechnology-enabled tissue engineering is receiving increasing attention. The ultimate goal of tissue engineering as a medical treatment concept is to replace or restore the anatomic structure and function of damaged, injured, or missing tissue. At the core of tissue engineering is the construction of three-dimensional scaffolds out of biomaterials to provide mechanical support and guide cell growth into new tissues or organs. Biomaterials can be variously permanent or biodegradable, naturally occurring or synthetic, but inevitably need to be biocompatible. Using nanotechnology, biomaterial scaffolds can be manipulated at atomic, molecular, and macromolecular levels. Creating tissue engineering scaffolds in nanoscale also may bring unpredictable new properties to the material, such as mechanical (stronger), physical (lighter and more porous) or chemical reactivity (more active or less corrosive), which are unavailable at micro- or macroscales. For bone tissue engineering, a special subset of ...
Polymers | Free Full-Text | Hydrogels for Cardiac Tissue Engineering
Cardiac tissue regeneration is an integrated process involving both cells and supporting matrix. Cardiomyocytes and stem cells are utilized to regenerate cardiac tissue. Hydrogels, because of their tissue-like properties, have been used as supporting matrices to deliver cells into infarcted cardiac muscle. Bioactive and biocompatible hydrogels mimicking biochemical and biomechanical microenvironments in native tissue are needed for successful cardiac tissue regeneration. These hydrogels not only retain cells in the infarcted area, but also provide support for restoring myocardial wall stress and cell survival and functioning. Many hydrogels, including natural polymer hydrogels, synthetic polymer hydrogels, and natural/synthetic hybrid hydrogels are employed for cardiac tissue engineering. In this review, types of hydrogels used for cardiac tissue engineering are briefly introduced. Their advantages and disadvantages are discussed. Furthermore, strategies for cardiac regeneration using hydrogels are

science24.com - A degradable and highly porous polyurethane scaffolds for bone tissue engineering
Scaffold-based tissue engineering requires for transplanted or host cells a biodegradable matrix, which provides a specific environment for tissue development. Efficiency of tissue regeneration through cell implantation in scaffolds depends mainly on the architecture of the scaffold and on the properties of the biomaterial used for their fabrication. The scaffold architecture is characterized by the pore shape and size, size distribution, pore interconnectivity and throat size. Among the polymers selected for tissue engineering, polyurethanes (PUR) represent a very important group. By varying the molecular weight of polyol and the composition of the hard segments, properties of PUR can be tuned for use in tissue engineering, either for reconstruction of soft tissue or for cartilage and bone regeneration. The objective of this study was to characterize polyurethane porous scaffolds fabricated by the salt-leaching/polymer coagulation method. The effect of solution concentration and salt particles ...
Heart valve and arterial tissue engineering : WestminsterResearch
In the industrialized world, cardiovascular disease alone is responsible for almost half of all deaths. Many of the conditions can be treated successfully with surgery, often using transplantation techniques; however, autologous vessels or human-donated organs are in short supply. Tissue engineering aims to create specific, matching grafts by growing cells on appropriate matrices, but there are many steps between the research laboratory and the operating theatre. Neo-tissues must be effective, durable, non-thrombogenic and non-immunogenic. Scaffolds should be bio-compatible, porous (to allow cell/cell communication) and amenable to surgery. In the early days of cardiovascular tissue engineering, autologous or allogenic cells were grown on inert matrices, but patency and thrombogenicity of grafts were disappointing. The current ethos is toward appropriate cell types grown in (most often) a polymeric matrix that degrades at a rate compatible with the cells production of their own extracellular ...

Dual-source dual-power electrospinning and characteristics of multifunctional scaffolds for bone tissue engineering. - Science...
Electrospun tissue engineering scaffolds are attractive due to their distinctive advantages over other types of scaffolds. As both osteoinductivity and osteoconductivity play crucial roles in bone tissue engineering, scaffolds possessing both properties are desirable. In this investigation, novel bicomponent scaffolds were constructed via dual-source dual-power electrospinning (DSDPES). One scaffold component was emulsion electrospun poly(D ,L -lactic acid) (PDLLA) nanofibers containing recombinant human bone morphogenetic protein (rhBMP-2), and the other scaffold component was electrospun calcium phosphate (Ca-P) particle/poly(lactic-co-glycolic acid) (PLGA) nanocomposite fibers. The mass ratio of rhBMP-2/PDLLA fibers to Ca-P/PLGA fibers in bicomponent scaffolds could be controlled in the DSDPES process by adjusting the number of syringes used to supply solutions for electrospinning. Through process optimization, both types of fibers could be evenly distributed in bicomponent scaffolds. The ...
IDEALS @ Illinois: Towards an autologous tissue engineering construct for craniofacial bone repair
Patients with critical-size bone defects, as a result of trauma, congenital malformations or tumor resections, generally have limited healing without clinical intervention. The autograft is the current standard of care for repair of these defects due to capacity for osteointegration and immunological compatibility. However, potential limitations, such as donor site morbidity, have motivated the development of alternative autologous approaches for the treatment of these defects. Materials used in tissue engineering, such as scaffolds, growth factors and adult stem cells, can be derived from patient blood and adipose tissue and are potential autologous therapeutic options. This dissertation investigates a prospective procedure to improve craniofacial bone healing using fibrin scaffolds and platelet rich plasma from patient blood, and adipose-derived stem cells from liposuction. The objectives of these studies are to evaluate the effects of fibrin scaffolds and platelet-rich plasma on ...

British Library EThOS: Biofunctionalised electrospun scaffolds for cartilage tissue engineering
The field of tissue engineering has advanced and evolved to focus on biomimetic strategies to meet the rise in demands of tissue replacements for surgical reconstruction. One of the key strategies focuses on developing growth factor delivery systems, by incorporating growth factors into tissue scaffolds. While growth factors are crucial cell-inducing components, their limitations such as short half-lives and dose related adverse effects remain a challenge. To overcome these challenges, this thesis is focused on the development of a novel biomimetic tissue scaffold concept incorporating cell-mediated activation of growth factors for cartilage regeneration. The latent transforming growth factor-β1 (TGF-β1) was selected as a model latent protein due to its well established effects on cartilage as well as its ubiquity in many other tissue types. The thesis first focused on the development and characterisation of the tissue scaffold. A non-woven fibrous scaffold was fabricated by electrospinning, ...

In this context, how cells colonize and interact with the biomaterial is critical in order to get a functional tissue engineering product. Cell-biomaterial interaction is referred to here as the phenomenon involved in adherent cells attachment to the biomaterial surface, and their related cell functions such as growth, differentiation, migration or apoptosis. This process is inherently complex in nature involving many physico-chemical events which take place at different scales ranging from molecular to cell body (organelle) levels. Moreover, it has been demonstrated that the mechanical environment at the cell-biomaterial location may play an important role in the subsequent cell function, which remains to be elucidated. In this paper, the state-of-the-art research in the physics and mechanics ...

The core of the PMCs is liquified and encapsulates human adipose stem cells and surface functionalized collagen II-TGF-β3 poly(L-lactic acid) microparticles for cartilage tissue engineering.. ...
Autologous satellite cell seeding improves in vivo biocompatibility of homologous muscle acellular matrix implants
Acellular matrix obtained from homologous muscular tissue has been previously used to repair muscular defects. However, the implants, although not rejected, give rise to an intense inflammatory response and are rapidly replaced by fibrous tissue. In this study we examined the possibility that co-culture with autologous satellite cells can improve the efficiency of homologous acellular matrix as skeletal muscle substitute. Satellite cells, isolated from rat dorsal muscle, were cultured in vitro on homologous acellular matrix obtained by detergent-enzymatic treatment of abdominal muscle fragments. Scanning electron microscopy revealed that after 24 h of co-culture satellite cells were attached to the matrix, but still possessed a round shape. After 96 h, seeded cells began to flatten and to differentiate, originating few multinucleated myotubes. Patches of homologous matrix, seeded or not with autologous satellite cells, were implanted in the dorsal muscle of rats. At autopsy, the implants were ...
Cartilage tissue engineering: towards a biomaterial-assisted mesenchymal stem cell therapy. - Semantic Scholar
Injuries to articular cartilage are one of the most challenging issues of musculoskeletal medicine due to the poor intrinsic ability of this tissue for repair. Despite progress in orthopaedic surgery, the lack of efficient modalities of treatment for large chondral defects has prompted research on tissue engineering combining chondrogenic cells, scaffold materials and environmental factors. The aim of this review is to focus on the recent advances made in exploiting the potentials of cell therapy for cartilage engineering. These include: 1) defining the best cell candidates between chondrocytes or multipotent progenitor cells, such as multipotent mesenchymal stromal cells (MSC), in terms of readily available sources for isolation, expansion and repair potential; 2) engineering biocompatible and biodegradable natural or artificial matrix scaffolds as cell carriers, chondrogenic factors releasing factories and supports for defect filling, 3) identifying more specific growth factors and the appropriate
3D scaffolds in tissue engineering and regenerative medicine: beyond s by Tierney GB Deluzio, Dawit Gezahegn Seifu et al.
The objective of this article is to systematically present the emerging understanding that 3D porous scaffolds serve not only as structural templates for tissue fabrication but also provide complex signaling cues to cells and facilitate oxygen and therapeutic agent delivery. Strategies in the field of tissue engineering and regenerative medicine often rely on 3D scaffolds to mimic the natural extracellular matrix as structural templates that support cell adhesion, migration, differentiation and proliferation, and provide guidance for neo-tissue formation. In addition to providing a temporary support for tissue fabrication, 3D scaffolds have also been used to study cell signaling that best mimics physiological conditions, thereby expanding our understanding beyond 2D cell cultures. It is now understood that cell responses to 3D scaffolds are distinctively different from 2D surfaces. Recently, 3D scaffolds emerged as a vehicle for improved oxygen transport to seeded cells and also to deliver relevant
Decellularizing Tissue Engineering Scaffolds with Carbon Dioxide - College of Engineering and Computing | University of South...
Many strategies for tissue engineering of replacement structures, such as heart valves, depend in part on preparing a tissue scaffold from a natural tissue matrix. An essential step in tissue scaffold fabrication is decellularization of the matrix. The objective of any decellularization method is twofold: (1) the preservation of the physical and biochemical properties of the extracellular matrix (ECM), and (2) the removal of all cellular material. Decellularization is currently done by contacting xenographic tissue with a combination of chemical detergents and biological agents. These processes can alter ECM structure and composition, which can trigger host immune response and inflammation. Currently, there are no accepted quantitative standards against which to certify the viability of the decellularized material. However, future standards will certainly include characteristics like removal of nuclear material, biochemical composition, and mechanical strength. We are evaluating a novel ...

Layered Scaffolds for Osteochondral Tissue Engineering | 3Bs Research Group in Biomaterials, Biodegradables and Biomimetics
Despite huge efforts, tissue engineers and orthopedic surgeons still face a great challenge to functionally repair osteochondral (OC) defects. Nevertheless, over the past decade great progress has been made to find a suitable strategy towards OC regeneration. In the clinics, some osteochondral tissue engineering (OCTE) approaches have already been applied although with some incongruous outcomes as OC tissue is complex in its architecture and function. In this chapter, we summarize current OCTE strategies that are focused on hierarchical scaffold design, mainly layered scaffolds. Most suitable candidates towards functional regeneration of OC tissues are envisaged from monophasic to the layered scaffolds. Herein is documented a variety of approaches with their intrinsic properties applied as bare scaffolds or in combination with biologics, either in in vitro or in vivo evaluations aiming at functional OC regeneration. The most noteworthy studies in OC regeneration developed within the past 5 years ...

TY - JOUR. T1 - Application of stem cells for articular cartilage regeneration.. AU - Hwang, Nathaniel S.. AU - Elisseeff, Jennifer. PY - 2009/1. Y1 - 2009/1. N2 - Articular cartilage is a highly organized tissue lacking self-regeneration capacity upon lesion. Current surgical intervention by application of in vitro-expanded autologous chondrocytes transplantation procedure is associated with several disadvantages, including donor-site morbidity and inferior fibrocartilage formation at the defect site. However, recent advancements in tissue engineering have provided notable strategies for stem cell-based therapies and articular cartilage tissue engineering. In this review, we discuss the current strategies to engineer cartilage tissues from adult stem cells and human embryonic stem cell-derived cells. The characteristics of adult stem cells, the microenvironmental control of cell fate determination, and the limitation imposed by the intrinsic nature of stem cells are discussed. The strategy to ...

Worldwide, an estimated 2.5 million people live with spinal cord injury, with more than 130,000 new injuries reported each year. Spinal cord injury has a significant impact on patients quality of life, life expectancy and economic burden, with considerable costs associated with primary care and loss of income. Stroke is currently the second leading cause of death in the Western world, ranking after heart diseases and before cancer, and could raise secondary dysfunctions too. In the case of focal brain ischemia and chronic spinal cord injuries, namely whenever an extensive loss of tissue occurs, cell therapy is helpful but not sufficient for the regeneration of the lost tissues. Within these regions, scaffolds are needed in order to provide physical support for axonal regeneration and for the transplanted cells to effectively integrate within the host tissues. To this purpose, tissue engineering, an interdisciplinary field of medical science bringing together the principles of material science, ...
Biomaterial scaffolds with keratin for tissue engineering - Patent application
0001]An enormous expenditure of health-care resources was required for the repair and replacement of diseased tissue structures and organs. The most common treatment, replacement with an autograft, produces less than optimal results. However, the supply of autograft, and even allograft, is very limited. Engineering tissues and organs with mammalian cells and a scaffolding material as emerged as a promising alternative approach in the treatment of malfunctioning or lost organs compared to the use of harvested tissues and organs (see Langer, R. S. and J. P. Vacanti, Tissue engineering: the challenges ahead, Scientific American 280(4), 86 (1999)). In this approach, a temporary scaffold is needed to serve as an adhesive substrate for the implanted cells and a physical support to guide the formation of the new organs. Accordingly, the scaffold materials must be custom-engineered to match the biomechanical, biochemical, and biological needs of the specific tissue or organ they are designed to ...
Cardiac Patch Market Size, Business Strategies, Product Sales and Growth Rate, Assessment to 2025 | DailyBN
Cardiac patch, which is a suitable alternative to heart transplant, recovers the heart tissue and ensures its sound functioning. The integration of advanced features such as therapeutic control through drug release is another groundbreaking innovation which is expected to be introduced in the cardiac patches and marketed globally in the coming decade. Such improvisations and additional features to the existing cardiac patches is anticipated to fuel the growth of the global cardiac patch market significantly during the 2017-2025 period. However, the limitations of cardiac patches such as the formation of aneurysms and the obstruction of growth potential because of ingrown tissue and calcification leads to multiple replacements and can hamper the market growth.. The global cardiac patch market can be segmented based on end-users and region. In terms of end-users, the market can be divided into hospitals and specialty clinics. The hospitals segment is likely to hold a major share in the global ...

TY - JOUR. T1 - Characterization of chitosan-gelatin scaffolds for dermal tissue engineering. AU - Tseng, Hsiang Jung. AU - Tsou, Tai Li. AU - Wang, Hsian Jenn. AU - Hsu, Shan hui. PY - 2013/1. Y1 - 2013/1. N2 - Porous scaffolds for dermal tissue engineering were fabricated by freeze-drying a mixture of chitosan and gelatin (CG) solutions. Different crosslinking agents including glutaraldehyde, 1-(3-dimethylaminopropyl)-3-ethyl-carbodimide hydrochloride (EDC), and genipin were used to crosslink the scaffolds and improve their biostability. The porous structure and mechanical properties were determined for the scaffolds. The proliferation of human fibroblasts in the scaffolds was analyzed. It was found that EDC crosslinked scaffolds had the greatest amount of cells after four days. EDC crosslinked CG scaffolds had tensile modulus in a dry state and compressive modulus in a wet state similar to commercial collagen wound dressing. They also showed appropriate pore size, high water absorption, and ...

The human tissue-engineered cornea as a model to study the impact of altering the PI3K/Akt signal transduction pathway on...
Purpose : Upon injury to the cornea, the composition of the extracellular matrix (ECM) rapidly changes to promote wound healing through its interactions with integrins. We hypothesize that ECM remodelling occurring during corneal wound healing causes the activation of very specific signal transduction mediators that favor faster closure of the wound. Our goal is to proceed to the pharmacological inhibition and/or activation of the PI3K/Akt mediators Akt and CREB using the human tissue-engineered cornea (hTECs) as a model. Methods : hTECs produced by the self-assembly approach were wounded with a 8-mm diameter biopsy punch and deposited on another reconstructed human corneal stroma to allow wound closure on a natural ECM. Total RNAs and proteins were prepared from the epithelial cells of wounded and unwounded areas and their gene expression pattern was determined by microarrays. The wounded tissues were then incubated with or without C646 (a CREB inhibitor) or with or without SC79 (an AKT ...

Research by RIT Professor Points to Improvements in Tissue Engineering | Microsystems Engineering | RIT
Thomas Gaborskis research may be in ultra-thin nano-membranes, but its going to be titanic in advancing tissue engineering.. Gaborski, assistant professor of biomedical engineering at Rochester Institute of Technology, and his research team are developing ways to use ultra-thin nano-membranes and adipose stem cells to create the vascular network necessary in engineering tissue, skin and organs.. For these organs to be viable, there is a need for not only the organ structure but also the inner network of micro-vessels and capillaries. Gaborski is helping develop that complex structure, using transparent and permeable membrane scaffolds to support cell and tissue growth, essential to tissue engineering.. Using adipose-derived stem cells that come from fat tissue, acquired from adults rather than embryos, Gaborski has been able to create functional microenvironments that help support and differentiate stem cells into the specialized cells that make up the human body. Creating engineered tissues ...
Combining Stem Cells and Biomaterial Scaffolds for Constructing Tissues and Cell Delivery **NEW** | StemBook
This review detailed the most commonly used biomaterial scaffolds for engineering tissues from stem cells by covering the types of materials available and their unique properties. This information allows readers to determine which material best suits their specific application. As mentioned in earlier in this review, many of these materials have not been fully optimized for specific tissue engineering applications and further work will continue to optimize these formulations for translation to the clinic for targeted applications. For example, optimized scaffolds could enhance the survival and differentiation of neural stem cells being transplanted into the diseased or damaged nervous system, which could lead to improved function. The type of material and the cues that are incorporated in the scaffold play a large role in directing the fate of the stem cells seeded inside as detailed in this review. The ability to further functionalize the materials discussed in this review in terms of their ...

2002). The tortuosity of scaffolds fabricated using solvent casting is not controllable because it requires the contact of the particulates during the fabrication procedure, which is a random process facilitated by using high humidity. Similarly, poor interconnectivity of pores is reported for scaffolds produced using gas foaming techniques, where only 10%À30% of the scaffolds pores are connected (Hutmacher, 2001). Control of pore size distribution in scaffolds fabricated using freeze-drying is an interesting research topic. 2010.

Eun Lee | Biomedical Engineering
Dr. Lee has spearheaded in the development of in vitro tissue models and novel bioreactors in the field of cardiovascular tissue engineering in the past several years. She has developed spontaneously beating heart chambers exhibiting key characteristics of native heart for the first time, which is truly novel and powerful for answering questions that cannot easily be approached in vivo. She has also developed a uniaxial and a biaxial stretching device, which can be used to study the impact of mechanical stimulation on engineered cardiac tissues. More importantly, she has developed a novel flow bioreactor, which allows culture of microvasculature in vitro under the influence of flow, which is critical for any functional tissues. To the best of her knowledge, this was the first gel-based flow bioreactor, which provide a new basis for subsequent co-culture studies with various cell types to develop complex engineered tissue constructs with vascularization capacity, which is extremely critical for ...
Influence of structural load-bearing scaffolds on mechanical load- and BMP-2-mediated bone regeneration
A common design constraint in functional tissue engineering is that scaffolds intended for use in load-bearing sites possess similar mechanical properties to the replaced tissue. Here, we tested the hypothesis that in vivo loading would enhance bone morphogenetic protein-2 (BMP-2)-mediated bone regeneration in the presence of a load-bearing PLDL scaffold, whose pores and central core were filled with BMP-2-releasing alginate hydrogel. First, we evaluated the effects of in vivo mechanical loading on bone regeneration in the structural scaffolds. Second, we compared scaffold-mediated bone regeneration, independent of mechanical loading, with alginate hydrogel constructs, without the structural scaffold, that have been shown previously to facilitate in vivo mechanical stimulation of bone formation.. Contrary to our hypothesis, mechanical loading had no effect on bone formation, distribution, or biomechanical properties in structural scaffolds. Independent of loading, the structural scaffolds ...

Mesenchymal stem cells and extracellular matrix scaffold promote muscle regeneration by synergistically regulating macrophage...
Skeletal muscle plays an important role in the bodys physiology but there are still no effective treatments for volumetric muscle loss (VML) resulting from severe traumatic injury or tumor excision. Recent studies show that a tissue engineering strategy using a compound containing mesenchymal stem cells (MSCs) and decellularized extracellular matrix (ECM) scaffold generates significant regenerative effects on VML injury, but the underlying mechanisms are not fully understood. The characteristics of human umbilical cord MSCs, including multiplication capacity and multidifferentiation ability, were determined. We constructed a compound containing MSCs and decellularized ECM scaffold which was used for tissue regeneration in a VML model. We found that MSCs and decellularized ECM scaffold generated synergistic effects on promoting skeletal muscle tissue regeneration. Interestingly, both MSCs and decellularized ECM scaffold could promote macrophage polarization toward the M2 phenotype and suppress
