Excitability and contractility of skeletal muscle engineered from primary cultures and cell lines. (1/58)

The purpose of this study was to compare the excitability and contractility of three-dimensional skeletal muscle constructs, termed myooids, engineered from C2C12 myoblast and 10T1/2 fibroblast cell lines, primary muscle cultures from adult C3H mice, and neonatal and adult Sprague-Dawley rats. Myooids were 12 mm long, with diameters of 0.1-1 mm, were excitable by transverse electrical stimulation, and contracted to produce force. After approximately 30 days in culture, myooid cross-sectional area, rheobase, chronaxie, resting baseline force, twitch force, time to peak tension, one-half relaxation time, and peak isometric force were measured. Specific force was calculated by dividing peak isometric force by cross-sectional area. The specific force generated by the myooids was 2-8% of that generated by skeletal muscles of control adult rodents. Myooids engineered from C2C12-10T1/2 cells exhibited greater rheobase, time to peak tension, and one-half relaxation time than myooids engineered from adult rodent cultures, and myooids from C2C12-10T1/2 and neonatal rat cells had greater resting baseline forces than myooids from adult rodent cultures.  (+info)

Injectable gels for tissue engineering. (2/58)

Recently, tissue engineering approaches using injectable, in situ gel forming systems have been reported. In this review, the gelation processes and several injectable systems that exhibit in situ gel formation at physiological conditions are discussed. Applications of selected injectable systems (alginate, chitosan, hyaluronan, polyethylene oxide/polypropylene oxide) in tissue engineering are also described. Injectable polymer formulation can gel in vivo in response to temperature change (thermal gelation), pH change, ionic cross-linking, or solvent exchange. Kinetics of gelation is directly affected by its mechanism. Injectable formulations offer specific advantages over preformed scaffolds such as: possibility of a minimally invasive implantation, an ability to fill a desired shape, and easy incorporation of various therapeutic agents. Several factors need to be considered before an injectable gel can be selected as a candidate for tissue engineering applications. Apart from tissue-specific cell-matrix interactions, the following gel properties need to be considered: gelation kinetics, matrix resorption rate, possible toxicity of degradation products and their elimination routes, and finally possible interference of the gel matrix with histogenesis.  (+info)

Tissue engineering strategies for adipose tissue repair. (3/58)

Tissue engineering is a relatively young field that combines engineering, clinical science, and life sciences to, in part, repair or regrow tissues. Adipose tissue has recently become a focus area for tissue engineering, encouraged by the large number of reconstructive, cosmetic, and correctional indications that could be addressed with clinically translatable adipose tissue engineering strategies. This review discusses the three aspects of an adipose construct, namely cell types, scaffold, and microenvironment, and presents current tissue engineering strategies under pursuit.  (+info)

Tissue engineering in the cardiovascular system: progress toward a tissue engineered heart. (4/58)

Achieving the lofty goal of developing a tissue engineered heart will likely rely on progress in engineering the various components: blood vessels, heart valves, and cardiac muscle. Advances in tissue engineered vascular grafts have shown the most progress to date. Research in tissue-engineered vascular grafts has focused on improving scaffold design, including mechanical properties and bioactivity; genetically engineering cells to improve graft performance; and optimizing tissue formation through in vitro mechanical conditioning. Some of these same approaches have been used in developing tissue engineering heart valves and cardiac muscle as well. Continued advances in scaffold technology and a greater understanding of vascular cell biology along with collaboration among engineers, scientists, and physicians will lead to further progress in the field of cardiovascular tissue engineering and ultimately the development of a tissue-engineered heart.  (+info)

Tissue engineering in plastic reconstructive surgery. (5/58)

Tissue engineering (TE) is a new interdisciplinary field of applied research combining engineering and biosciences together with clinical application, mainly in surgical specialities, to develop living substitutes for tissues and organs. Tissue engineering approaches can be categorized into substitutive approaches, where the aim is the ex vivo construction of a living tissue or organ similar to a transplant, vs. histioconductive or histioinductive concepts in vivo. The main successful approaches in developing tissue substitutes to date have been progresses in the understanding of cell-cell interactions, the selection of appropriate matrices (cell-matrix interaction) and chemical signalling (cytokines, growth factors) for stimulation of cell proliferation and migration within a tissue-engineered construct. So far virtually all mammalian cells can be cultured under specific culture conditions and in tissue specific matrices. Future progress in cell biology may permit the use of pluripotent stem cells for TE. The blueprint for tissue differentiation is the genome: for this it is reasonable to combine tissue engineering with gene therapy. The key to the progress of tissue engineering is an understanding between basic scientists, biochemical engineers, clinicians, and industry.  (+info)

Engineering of vascular ingrowth matrices: are protein domains an alternative to peptides? (6/58)

Anastomotic intimal hyperplasia and surface thrombogenicity are the main reasons for the high failure rate of prosthetic small-diameter vascular grafts. While anastomotic intimal hyperplasia is a multifactorial event, ongoing surface thrombogenicity is primarily caused by the lack of an endothelium, even after years of clinical implantation. After decades of poorly performing synthetic artery-grafts, tissue engineering has emerged as a promising approach to generate biologically functional bio-synthetic hybrid grafts mimicking native arteries regarding the presence of an endothelial lining on the blood surface. "In vitro endothelialization" represented the first generation of such tissue-engineered vascular grafts, utilising cell culture techniques for the creation of a confluent autologous endothelium on ePTFE grafts. The clinical long-term results with this method in almost 200 patients are highly encouraging, showing patencies equal to vein grafts. Since "in vitro endothelialization" requires cell culture facilities, it will always be confined to large centres. Therefore, research of the 1990s turned to the development of spontaneously endothelializing implants, to make tissue-engineered grafts amenable to the entire vascular-surgical community. Apart from scaffold designs allowing transmural ingrowth, biological signalling through a facilitating ingrowth matrix holds a key to spontaneous endothelialization. In biological signalling, the increasingly deeper understanding of bio-active molecules and the discovery of domains and peptide sequences during the 1980s created the expectation in the 1990s that peptide signalling may be all that is needed. This present review highlights the possible problems associated with such a reductionist approach. Using the fibronectin molecule, we demonstrated that domains may be more suitable modules in tissue engineering than peptide sequences.  (+info)

Peripheral nerve injury: a review and approach to tissue engineered constructs. (7/58)

Eleven thousand Americans each year are affected by paralysis, a devastating injury that possesses associated annual costs of $7 billion (American Paralysis Association, 1997). Currently, there is no effective treatment for damage to the central nervous system (CNS), and acute spinal cord injury has been extraordinarily resistant to treatment. Compared to spinal cord injury, damage to peripheral nerves is considerably more common. In 1995, there were in excess of 50,000 peripheral nerve repair procedures performed. (National Center for Health Statistics based on Classification of Diseases, 9th Revision, Clinical Modification for the following categories: ICD-9 CM Code: 04.3, 04.5, 04.6, 04.7). These data, however, probably underestimate the number of nerve injuries appreciated, as not all surgical or traumatic lesions can be repaired. Further, intraabodominal procedures may add to the number of neurologic injuries by damage to the autonomic system through tumor resection. For example, studies assessing the outcome of impotency following radical prostatectomy demonstrated 212 of 503 previously potent men (42%) suffered impotency when partial or complete resection of one or both cavernosal nerve(s). This impotency rate decreased to 24% when the nerves were left intact (Quinlan et al., J. Urol. 1991;145:380-383; J. Urol. 1991;145:998-1002).  (+info)

Self-assembly and mineralization of peptide-amphiphile nanofibers. (8/58)

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)

Bioartificial implants and methods for their manufacture and use are described, particularly bioartificial pancreases. In particular, the implants may be thin sheets which enclose cells, may be completely biocompatible over extended periods of time and may not induce fibrosis. The high-density-cell-containing thin sheets are preferably completely retrievable, and have dimensions allowing maintenance of optimal tissue viability through rapid diffusion of nutrients and oxygen and also allowing rapid changes in the secretion rate of insulin and/or other bioactive agents in response to changing physiology. Implantations of living cells, tissue, drugs, medicines and/or enzymes, contained in the bioartificial implants may be made to treat and/or prevent disease.

We developed a bioartificial tissue (TraVaSc-TERM ®) for the surgical reconstruction of extensive tracheo-bronchial defects including circumferent airway replacement. The tissue is generated from a xenogene biological scaffold [pig intestine, -LS] that is decellularized, preserving the structure of the vascular network. For transplant generation, these vascular structures are reseeded with autologous endothelial precursor cells of the recipient. Two more autologous cell types are needed to generate a functional airway substitute. Our approach results in a vascularized autologous transplant tissue that can be connected to the recipients blood supply at time of implantation to guarantee transplant survival. Tissue generation takes about five weeks. The TraVaSc-TERM ® was applied successfully in three patients between 2006 and 2009 [actually, it seems one patient was counted as two, -LS]. As a result of the ATMP-legislation in Europe the TraVaSc-TERM ®-generation process had to be transferred ...
Size and function of bioartificial tissue models are still limited due to the lack of blood vessels and dynamic perfusion for nutrient supply. In this study, we evaluated the use of cytocompatible methacryl-modified gelatin for the fabrication of a hydrogel-based tube by dip-coating and subsequent photo-initiated cross-linking. The wall thickness of the tubes and the diameter were tuned by the degree of gelatin methacryl-modification and the number of dipping cycles. The dipping temperature of the gelatin solution was adjusted to achieve low viscous fluids of approximately 0.1 Pa s and was different for gelatin derivatives with different modification degrees. A versatile perfusion bioreactor for the supply of surrounding tissue models was developed, which can be adaped to several geometries and sizes of blood-vessel mimicking tubes. The manufactured bendable gelatin tubes were permeable for water and dissolved substances, like Nile Blue and serum albumin. As a proof of concept, human fibroblasts ...

The main role of the kidneys is to filter and eliminate waste, fluid, and minerals from the blood by producing urine. When the two bean-shaped organs lose this ability, waste and fluids accumulate in the body and thus elevate blood pressure levels and lead to kidney failure..

Bernhard Jank et al, Engineered Composite Tissue as a Bioartificial Limb Graft, Biomaterials (August 2015), 61:246-56. The abstract reads as follows: The loss of an extremity is a disastrous injury with tremendous impact on a patients life. Current mechanical prostheses are technically highly sophisticated, but only partially replace physiologic function and aesthetic appearance. As a biologic alternative, approximately 70 patients have undergone allogeneic hand transplantation to date worldwide. While outcomes are favorable, risks and side effects of transplantation and long-term immunosuppression pose a significant ethical dilemma. An autologous, bio-artificial graft based on native extracellular matrix and patient derived cells could be produced on demand and would not require immunosuppression after transplantation. To create such a graft, we decellularized rat and primate forearms by detergent perfusion and yielded acellular scaffolds with preserved composite architecture. We then ...
An emerging treatment for patients with failing valves, TVR entails implanting a prosthetic valve through the skin, using catheterization to forgo more invasive surgery. Going through the groin area, a catheter containing a replacement valve is guided to the location of the failing valve.

Due to his experience working with stem cells, Cady was recruited for a pivotal role in a groundbreaking surgery that occurred in April 2013. He provided the technical expertise necessary to successfully generate a tissue-engineered bioartificial trachea for transplant into 2-year-old Hannah Warren - the first such transplant in the United States.. When Warren was born, the doctors in her Seoul, South Korea-based hospital noticed she was blue and immediately inserted a tube from her throat to her lungs, so she could breathe. A CT scan revealed she was born with tracheal agenesis - the lack of a complete trachea. This condition required Warren to have both breathing and feeding tubes to live.. Dr. Mark Holterman, a pediatric surgeon at Childrens Hospital of Illinois, learned of Warrens plight while on a business trip in Seoul. He soon returned to meet with her parents, Darryl and Young Mi, offering to help find a solution that might save the girl; it took him two years to make the surgery a ...
Assist organ replacements and biotechnology research: Human organs are known to fail due to a variety of reasons like illness or injury putting lives at risk. Genetic engineering provides the fundamental basis for the process of transplanting organs or living tissues from animals to human beings. Already, there have been huge advancements in the science of transplanting organs from pigs to humans for replacing damaged hearts and kidneys. There is also a great sense of anticipation for the expected breakthroughs in tissue engineering that will pave the way for alternatives to cartilage replacement, heart valves, cerebrospinal shunts, and more.. Help to eradicate global shortage of food: Right from increasing crop productivity to making seeds and plants more insect and pest-resistant to produce with improved size, taste, sweetness, genetic modification of food crops and fruits has been hailed as one of the biggest steps taken by making to eradicate the shortage of foods world over.. Help get rid ...
Engineered tissues are highly limited by poor vascularization in vivo, leading to hypoxia. In order to overcome this challenge, we propose the use of photosynthetic biomaterials to provide oxygen. Since photosynthesis is the original source of oxygen for living organisms, we suggest that this could be a novel approach to provide a constant source of oxygen supply independently of blood perfusion. In this study we demonstrate that bioartificial scaffolds can be loaded with a solution containing the photosynthetic microalgae Chlamydomonas reinhardtii, showing high biocompatibility and photosynthetic activity in vitro. Furthermore, when photosynthetic biomaterials were engrafted in a mouse full skin defect, we observed that the presence of the microalgae did not trigger a native immune response in the host. Moreover, the analyses showed that the algae survived for at least 5days in vivo, generating chimeric tissues comprised of algae and murine cells. The results of this study represent a crucial ...
Of course, the implication here is obvious: if one can do this with hearts, one can do it for almost any organ in the body once they wear out and need replacement: Maybe, in ten years, the article concludes, there will be organ printers in the finest hospitals around the world, and these procedures will be conducted routinely.. Probably so. One can even envision a time or circumstance that the technology becomes so commonplace that the procedure becomes cheap, affordable, and can be done by licensed organ printers rather than doctors, in a kind of out patient procedure. And while were indulging in all this high octane speculation, one my even envision a kind of organ dealership or Jiffy Lube, a kind of drive-through organ replacement garage, complete with warranties and expiration dates, and so on.. Now, on the one hand, I can see that this developing technology is a good thing, because it extends life, and life is a good thing. Call me old fashioned, but I believe ardently in the ...

OBJECTIVE: To analyze the effects of an extracorporeal bioartificial liver containing alginate bead-entrapped hepatocytes on pigs with ischemia-induced acute hepatic failure. DESIGN: Prospective animal study. SETTING: University and INSERM laboratory. SUBJECTS: Fifteen Large White/Pietrin female pigs weighing 20-30 kg. INTERVENTIONS: Acute hepatic failure was induced by end-to-side portocaval shunt and ligature of the whole porta hepatitis. The bioartificial liver was in a thermostabilized column, containing a fluidized bed of alginate beads that embedded porcine hepatocytes, connected to a plasmapheresis system. Intracranial pressure; survival; ammonia, total bilirubin, aminotransferases, alkaline phosphatase, and lactate concentrations; and clotting factors were studied. The groups were pigs with acute hepatic failure (group 1, n = 4), pigs with acute hepatic failure treated with bioartificial liver containing empty beads (group 2, n = 4), or porcine hepatocytes (group 3, n = 5). MEASUREMENTS ...
Nanoporous membranes engineered to mimic natural filtration systems can be used in smart implantable drug delivery systems, bioartificial organs, and other novel nano-enabled medical devices. The ultrananocrystalline diamond (UNCD) porous membranes will open new opportunities in implant medicine because of the highest, unmatched by other materials degree of biocompatibility and anti-biofouling. We report our results on high porosity high-aspect-ratio UNCD membranes fabricated using e-beam lithography, reactive ion etching and laser writing.
Artificial kidney is often a synonym for hemodialysis, but may also, more generally, refer to renal replacement therapies (with exclusion of kidney transplantation) that are in use and/or in development. This article deals with bioengineered kidneys/bioartificial kidneys that are grown from renal cell lines/renal tissue. The first successful artificial kidney was developed by Willem Kolff in the Netherlands during the early 1940s. Kolff was the first to construct a working dialyzer in 1943. Kidneys are paired vital organs located behind the abdominal cavity at the bottom of the ribcage corresponding to the levels T12-L3 of the spine vertebrae. They perform about a dozen physiologic functions and are fairly easily damaged. Some of these functions include filtration and excretion of metabolic waste products, regulation of necessary electrolytes and fluids and stimulation of red blood cell-production. These organs routinely filter about 100 to 140 liters of blood a day to produce 1 to 2 liters of ...

Supported by an RPB Unrestricted Grant to the University of Washington School of Medicine, Dr. Jennifer Chao is assessing the ability of thousands of small molecules to enhance the survival of retinal cells created from AMD patient-specific stem cells. This is an important step in discovering disease- and patient-specific therapeutic drugs.. The idea that stem cells - the precursors of all body tissues - could be turned into organ replacements for diseased body parts has tantalized physicians and patients for decades. Scientists have been able to increase the availability of stem cells by developing techniques to transform a patients skin and blood cells into a primitive stem cell state from which all forms of human cells can, theoretically, be coaxed. These human induced pluripotent stem cells (hIPSC) have the added benefit of appearing to the patients immune system as native tissue and avoiding attack by the bodys immune response.. Ultimately, vision researchers hope to use a patients own ...

In this issue, 2 groups report on the outcomes of patients receiving dialysis in Canada. Given the intricacies of providing dialysis care, one would not expect easy answers from any evaluation. Using the Canadian Organ Replacement Register, investigators from both groups identify some potential improvements and, not surprisingly, some significant challenges. First, the good news. In an analysis restricted to patients aged 65 or older at dialysis inception, Jassal and colleagues report that survival improved from 1990 to 1999, despite increased comorbidities.1 Tonelli and colleagues, however, report that living far from an attending nephrologist is associated with decreased survival.2 Even when age and burden of comorbidity were accounted for, the authors found a stepwise increase in mortality with increasing distance, an association that was especially marked for death from infectious causes.. Even though dialysis treatment for end-stage renal disease has been saving the lives of countless ...

  • In the coming years, due to the aging of the population and the low availability of donor organs there will be urgent need for bioengineering solutions to assist, mimic or replace failing patient organs. (
  • However, its outcomes are limited by shortage of donor organs and the side effects of harsh immunosuppressive treatments designed to prevent the body from rejecting the organ. (
  • The goal is to create various whole organs that are derived from a patient's own cells, and transplanting them into patients, avoiding the need for a donor. (
  • For this reason, organ donor recipients have to take drugs that suppress the immune system. (
  • Dr. Macchiarini has used scaffolds to successfully replace windpipes from cadavers in about a dozen patients who don't have the major problem facing other organ donor recipients: the risk of organ rejection. (
  • But scaffolds still have some problems of traditional organ transplants: They require donor organs, for which there is a long waiting list, and the patient has to wait for the organ to be stripped of cells. (

  • After all the cells were gone (in three days), what was left of the organs was the scaffold, the basic shape of the organ, composed of a matrix of proteins and other compounds that keep the right cells in the right places. (
  • In contrast, organ specific properties can vary from time to time e.g. for the trachea air- and liquid-tight seals, flexibility and strength to prevent the collapse of the scaffolds, and must be considered when choosing the ideal scaffold. (

  • Tissue engineering is a set of biomedical, biotechnological and engineering techniques that aim to maintain, regenerate or replace tissues or organs. (
  • The creation of a transplantable, bioengineered kidney that can permanently replace kidney function could address this severe organ shortage and, at the same time, allow recipients to avoid the side effects of immunosuppressant drugs. (
  • However, the shortage of available organs, as well as the high rate of organ rejection, supports the need for new therapies. (
  • Blood pressure crashes, starving the body of oxygen, and in short order the lungs, liver, and other organs begin to fail. (
  • He now plans to use the technique to recreate more complex tissues, such as the esophagus and diaphragm or organs such as the heart and lungs. (

  • It's pretty obvious that with advances in stem cell technology, computer science, engineering and 3D printing, we will one day be able to create bioartificial tissue and implantable organs," said Markus Reiterer, senior principal scientist at Medtronic. (
  • To address these problems, researchers have turned to using cell-based therapies for the development of a bioartificial kidney. (
  • These results may open the door for the clinical application of various sophisticated bioartificial tissue substitutes and organ replacements. (
  • So far, only a few such organs have been created and transplanted, and the they aren't complex organs -- just simples one like bladders and a windpipe. (
  • For complex organs, such as heart, lung or the liver, cell therapy and pharmaceutical intervention can be an optimum alternative. (
  • But scientists around the world are using similar techniques with the goal of building more complex organs. (
  • Tissue engineers caution that the work they are doing is experimental and costly, and that the creation of complex organs is still a long way off. (

  • And it's only one example of the increasingly popular strategy of using living cells to do the heavy lifting in artificial organs. (
  • Scientists are beginning to come up with a way to help patients who need organ transplants: to create them a new organ using their own cells. (
  • Scientists are having preliminary success with a new way to get patients new organs that they may need: bioartificial organs made of plastic and the patient's own cells. (

  • Co-culturing with the HSC-Li cells improved the liver-specific functions of hepatocytes, which may be valuable and applicable for bioartificial liver systems. (
  • The (bio)artificial organs chair of Professor Dimitrios Stamatialis focuses on the development of novel immune-protective membrane-based cell encapsulation devices, containing insulin producing cells for regulation of blood glucose in T1D, without the need for injections and immunosuppressive drugs. (
  • First, the discarded organs were washed in a mild detergent to remove all cells, a process that is known as decellularization. (
  • The idea is based on evidence that the decellularized organs contain proteins and other substances that play a vital role in the survival, welfare and function of the organ's cells. (
  • In theory, these organ structures could be re-populated with a patient's own cells. (
  • In both cases, the organs structures were cell-friendly and allowed the cells to attach, function and maintain their original cell type. (
  • Now, however, researchers like Dr. Macchiarini are building organs with a different approach, using the body's cells and letting the body itself do most of the work. (
  • They want to make organs with the cells, blood vessels and nerves to become a living, functioning part of the body. (
  • These studies provide a proof of concept for using oxygen-generating materials to solve one of the major obstacles to engineering a bioartificial pancreas - making sure the cells have enough oxygen to function until the structure integrates with the body," said lead scientist Emmanuel C. (
  • As a substitute to these options, scientists are working to build a bioartificial pancreas by encapsulating insulin-producing cells within tiny biocompatible beads. (
  • The "renal assist device" (RAD) is a bioartificial kidney - a device lined with human renal tubular cells grown from donated organs. (
  • these acellular scaffolds retain the native organ ultrastructure and can be seeded with autologous cells towards the goal of regenerating functional tissues. (
  • One of the models suitable for this application is an organoid - a miniature organ, grown from adult stem cells. (
  • The culture of kidney organoids can be made compatible with the development of the bioartificial kidney - a filter containing living kidney cells, that might someday be able to replace conventional dialysis. (
  • We also have resident stem cells in every organ of the body. (
  • Through her pioneering work, we now have the capability to deplete animal and human hearts of all of their cellular structure and regenerate the "decellularized" scaffolds into healthy organs by the infusion of stem cells. (
  • Many believe that these "bioartificial" organs are the early steps toward our ability to grow new organs for people using their own adult stem cells. (
  • Artificial organs are another possible lifesaver, but like gene-editing pig cells to create transplantable organs, the technology is not complete. (
  • February 9, 2018 -- Medical researchers envision a day when a sick person with a diseased heart or other organ can get a new one, designed on a computer, made specifically for their personal anatomy and created from stem cells, or perhaps even their own cells, on a 3D printer. (
  • Ideally, the resulting extracellular matrices would retain the organ-specific architecture and chemical composition to guide implanted cells into functional structures and eventually working organs. (
  • If recognition of these phenomena is utilized in strategies for handling cells, then these cells (of any tissue and from any species) can be maintained as stem cells or as one of the intermediates in the maturational cell lineages or as fully mature cells ex vivo in monolayer cultures, in organoid cultures (floating aggregates of the cells), or as bioartificial organs in perfusion bioreactors. (
  • Addition of Bmp7 further enhanced the ability of these cells to contribute to developing tubules in a kidney organ culture system. (

  • RM aims to replace and regenerate damaged tissue to restore organ function. (
  • There are some human organs and tissues that regenerate rather than simply scar, as a result of injury. (
  • Therefore, to regenerate hollow organs and tissues with a long diffusion distance, the tissue had to be regenerated inside the lab, via the use of a 3D printer. (
  • Most of human tissues and organs do not regenerate spontaneously, justifying why cell therapy is today a significant tissue and organ repair strategy. (

  • Many studies used several techniques that are herein presented, including biopolymers, decellularization and bioreactors, and made significant advances, either seeking a graft or an entire bioartificial heart. (
  • others have artificial organs - from increasingly sophisticated prosthetic limbs to bionic eyes and ears. (
  • Herein, an overview of the current literature for kidney decellularization and whole-organ recellularization is presented, addressing the pros and cons of the actual techniques already developed, the methods adopted to evaluate the efficacy of the procedures, and the challenges to be overcome in order to achieve an optimal protocol. (
  • Such scaffolds may be produced through the decellularization of whole organs. (
  • They can connect the blood vessels of the two artificial organs , thereby modelling not just the organs themselves, but the interactions between them. (
  • Despite early clinical applications for the trachea, bladder, skin or heart valves, more solid organs can probably never be transferred to the patient regarding their demanding and complicated engineering process. (
  • Level four was solid organs, which were by far the most complex to recreate due to the vascularity. (
  • Some, like Dr. Macchiarini, want to go even further - to harness the body's repair mechanisms so that it can remake a damaged organ on its own. (
  • So far, only a few organs have been made and transplanted, and they are relatively simple, hollow ones - like bladders and Mr. Beyene's windpipe, which was implanted in June 2011. (
  • This chair has the ambition, to take-on the challenge of helping the patients by developing (bio) artificial organs. (
  • Bioartificial organs' most compelling use may be for kidney failure patients. (
  • The goal of both projects is to develop a new, potentially inexhaustible source of organs that would not require patients to take powerful anti-rejection drugs. (
  • Some of the other factors such as advancement in the medical bionics, rising ageing population, lack of organ donors, and increasing number of road accidents are some of the factors which will drive the bioartificial organ manufacturing market in the forecast period of 2020 to 2027. (
  • The goal of the research was to test the suitability of pancreata from organ donors as a platform for building a new bio-artificial pancreas. (
