Although limited clinical trials of stem cell therapy have been initiated in a number of neurological disorders, the preclinical evidence of a cell-based therapy for neonatal HI injury remains in its infancy. Stem cell therapy, via stimulation of endogenous stem cells or transplantation of exogenous stem cells, has targeted neurogenic sites, such as the hippocampus, for brain protection and repair. The hippocampus has also been shown to secrete growth factors, especially during the postnatal period, ...

Zong, Z-W., Cheng, T-M., Su, Y-P., Ran, X-Z., Shen, Y., Li, N., Ai, G-P., Dong, S-W. and Xu, H. Recruitment of Transplanted Dermal Multipotent stem Cells to the Sites of Injury in Rats with Combined Radiation and Wound Injury by Interaction of SDF-1 and CXCR4. Radiat. Res. 170, 444-450 (2008).. Systemic transplantation of dermal multipotent stem cells has been shown to accelerate both hematopoietic recovery and wound healing in rats with combined radiation and wound injury. In the present study, we explored the mechanisms governing the recruitment of dermal multipotent stem cells to the sites of injury in rats with combined injury. Male dermal multipotent stem cells were transplanted into female rats, and using quantitative real-time PCR for the sex-determining region of Y chromosome, it was found that the amounts of dermal multipotent stem cells in irradiated bone marrow and wounded skin were far greater than those in normal bone marrow and skin (P , 0.01). However, incubation of dermal ...

As MSCs are applied locally to target organs or home there after systemic administration, they experience diverse microenvironments that are biochemically and biophysically distinct. Here we use well-defined in vitro conditions to study the impact of substrate elasticity on MSC-derived trophic factors. By varying hydrogel compliance, the elasticity of brain and muscle tissue was mimicked. We screened ,90 secreted factors at the protein level, finding a diverse elasticity-dependent expression pattern. In particular, IL-8 was up-regulated as much as 90-fold in MSCs cultured for 2days on ...

Multipotent stromal cells (MSCs) are currently in clinical trials for a number of inflammatory diseases. Recent studies have demonstrated the ability of MSCs to attenuate inflammation in rodent models of acute lung injury (ALI) suggesting that MSCs may also be beneficial in treating ALI. To better understand how human MSCs (hMSCs) may act in ALI, the lungs of immunocompetent mice were exposed to lipopolysaccharide (LPS) and four hours later bone marrow derived hMSCs were delivered by oropharyngeal aspiration (OA). The effect of hMSCs on lung injury was assessed by measuring the lung wet/dry weight ratio and total protein in bronchoalveolar lavage (BAL) fluid 24 or 48 h after LPS. BAL fluid was also analyzed for the presence of inflammatory cells and cytokine expression by multiplex immunoassay. Microarray analysis of total RNA isolated from treated and untreated lungs was performed to elucidate the mechanism(s) involved in hMSC modulation of lung inflammation. Administration of hMSCs significantly

Multipotent stromal cells (MSCs) are being studied in the field of regenerative medicine for their multi-lineage differentiation and immunoregulatory capacity. MicroRNAs (miRNAs) are short non-coding RNAs that are responsible for regulating gene expression by targeting transcripts, which can impact MSC functions such as cellular proliferation, differentiation, migration and cell death. miRNAs are expressed in MSCs; however, the impact of miRNAs on cellular functions and donor variability is not well understood. Eight MSC lines were expanded to passages 3, 5 and 7, and their miRNA expression was evaluated using microarray technology. Statistical analyses of our data revealed that 71 miRNAs out of 939 examined were expressed by this set of MSC lines at all passages and the expression of 11 miRNAs were significantly different between passages 3 and 7, while the expression of 7 miRNAs was significantly different between passages 3 and 5. The expression of these identified miRNAs was evaluated using RT-qPCR

Because stem cells are often found to improve repair tissue including heart without evidence of engraftment or differentiation, mechanisms underlying wound healing are still elusive. Several studies have reported that stem cells can fuse with cardiomyocytes either by permanent or partial cell fusion processes. However, the respective physiological impact of these two processes remains unknown in part because of the lack of knowledge of the resulting hybrid cells. To further characterize cell fusion, we cocultured mouse fully differentiated cardiomyocytes with human multipotent adipose-derived stem (hMADS) cells as a model of adult stem cells. We found that heterologous cell fusion promoted cardiomyocyte reprogramming back to a progenitor-like state. The resulting hybrid cells expressed early cardiac commitment and proliferation markers such as GATA-4, myocyte enhancer factor 2C, Nkx2.5, and Ki67 and exhibited a mouse genotype. Interestingly, human bone marrow-derived stem cells shared similar

Background Locks bulge progenitor cells (HBPCs) are multipotent stem cells derived from the bulge region of mice vibrissal hairs. cell-permeable molecule called Cardiogenol C. We founded that Cardiogenol C could induce HBPCs to express transcription factors GATA4 Nkx2.5 and Tbx5 which are early specific markers for pre-cardiomyogenic cells. In long term ethnicities the Cardiogenol C-treated HBPCs can also express muscle mass proteins cardiac-specific troponin I and sarcomeric myosin weighty chain. However we did not observe the ability of the cells to functionally agreement. We called these cells cardiomyocyte-like cells instead of cardiomyocytes Therefore. We tried to treat this insufficiency by pre-treating HBPCs with Valproic acidity first before revealing these to Cardiogenol C. This pretreatment inhibited instead of improved the potency of Cardiogenol C in reprogramming the HBPCs. We utilized comparative proteomics to regulate how Cardiogenol C proved helpful by identifying protein MLN4924 ...

N2 - While the adult murine lung utilizes multiple compartmentally restricted progenitor cells during homeostasis and repair, much less is known about the progenitor cells from the human lung. Translating the murine stem cell model to humans is hindered by anatomical differences between species. Here we show that human bronchial epithelial cells (HBECs) display characteristics of multipotent stem cells of the lung. These HBECs express markers indicative of several epithelial types of the adult lung when experimentally tested in cell culture. When cultured in three different three-dimensional (3D) systems, subtle changes in the microenvironment result in unique responses including the ability of HBECs to ...

However, most current harvest techniques for embryonic stem cells require the destruction of embryos, which has led to significant political and ethical limitations on their usage. Parthenogenesis, the process by which an egg can develop into an embryo in the absence of sperm, may be a potential source of embryonic stem cells that may avoid some of the political and ethical concerns surrounding embryonic stem cells. Here we provide the technical aspects of embryonic stem cell isolation and expansion from the parthenogenetic ...

New research, published in BioMed Centrals open access journal Stem Cell Research & Therapy, investigates the therapeutic use of human stem cells from bone marrow against acute lung injury and identifies TNF-Ã ±-induced protein 6 as a major molecular component of stem cell action.. Acute lung injury is a major complication of critically ill patients resulting in pulmonary edema, hypoxia and, in the worst cases, organ failure. Consequently up to 40% of all sufferers die because their bodies immune systems overreact in an attempt to repair the original lung damage.. Researchers based in Louisiana showed that therapy with human multipotent stromal cells (hMSC) isolated from bone marrow was able to significantly reduce acute lung injury in mice after 48 hours. At 24 hours the therapy could be seen to be working, reducing the amount of pulmonary edema and protein in the lungs. While injury increased the number of white blood cells (neutrophils) ten fold, this could be reduced by treatment with ...

The authors induced SCI in 10 dogs by percutaneous balloon compression. The 10 injured dogs were assigned randomly to the following groups (2 dogs each): Group 1, evaluated 2 weeks after sham transplantation; Group 2, evaluated 2 weeks after transplantation; Group 3, evaluated 4 weeks after sham transplantation; Group 4, evaluated 4 weeks after transplantation; and Group 5, evaluated 4 weeks after multispot transplantations. The dogs with sham transplantation (Groups 1 and 3) received the same volume of saline, as a control. A spinal needle was advanced into the spinal canal, and the investigators confirmed that the end of the spinal needle was located in the ventral part of spinal cord parenchyma by using contrast medium under fluoroscopic guidance. The hUCB-derived MSCs were transplanted into the cranial end of the injured segment in 6 injured dogs at 7 days after SCI. ...

Introduction: Inflammation plays a crucial role in tissue regeneration, wound healing, and the success of tissue-engineered constructs. The aim of this study was to investigate the influence of human umbilical vein endothelial cells (ECs) on leukocyte transmigration when co-cultured with primary human bone marrow-derived multipotent stromal cells (MSCs). Methods: MSCs with and without ECs were cultured in poly (L-lactide-co-1, 5-dioxepan-2-one) (poly (LLA-co-DXO)) scaffolds for 1 week in vitro in a bioreactor system, after which they were implanted subcutaneously in non-obese diabetic/severe combined immunodeficient mice. After 1 and 3 weeks, scaffolds were retrieved, and the mRNA expression of interleukin 1-beta (IL-1 beta), IL-6, IL-10, hypoxia-inducible factor 1-alpha (HIF-1 alpha), HIF-1 beta, and mammalian target of rapamycin was examined by real-time reverse transcription-polymerase chain reaction. Furthermore, immunofluorescent staining was performed for IL-1 beta, IL-6, neutrophils, and ...

Pancreatic organogenesis proceeds through several crucial regulatory stages (Cleaver and MacDonald, 2010; Rieck et al., 2012): (1) specification and emergence of the pancreatic epithelial buds from the distal foregut endoderm; (2) expansion of an early pancreatic progenitor cell population and developmental commitment; (3) formation of a more restricted multipotent progenitor cell (MPC) population for endocrine, ductal and acinar tissues; (4) separation of committed pre-acinar cells at the tips of epithelial branches and a bipotent cell-population for islets and ducts in more central trunk domains; (5) separation of the endocrine and ductal programs, morphogenetic resolution of a precursor ductal plexus and completion of cell type-specific differentiation. This process creates three interrelated tissues: the islets of Langerhans (endocrine cells that produce polypeptide hormones, including insulin and glucagon), acini (exocrine cells that produce and secrete hydrolytic digestive enzymes) and ...

Autologous hematopoietic stem cell transplantation (auto-HSCT) are considered the standard of care for many malignancies, such as lymphoma, myeloma and some leukemias, and so on. Graft failure after auto-HSCT is a formidable complication. It occurs in 2-9.5% of patients and is associated with considerable morbidity and mortality related to infections and hemorrhagic complications. There are various options for the management of graft failure. The most common treatment of graft failure is growth factors such as granulocyte colony-stimulating factor (G-CSF)and recombinant erythropoietin,but it usually effective in the short term and no effect on platelet counts.. Mesenchymal stem cells (MSCs) are a form of multipotent adult stem cells that can be isolated from bone marrow (BM), adipose tissue, and cord blood. Clinical applications of human MSCs are evolving rapidly with goals of improving hematopoietic engraftment, preventing and treating graft-versus-host disease (GVHD) after allogeneic ...

Previous studies have shown that Meis1 plays an important role in blood development and vascular homeostasis, and can induce blood cancers, such as leukemia. However, its role in epithelia remains largely unknown. Here, we uncover two roles for Meis1 in the epidermis: as a critical regulator of epidermal homeostasis in normal tissues and as a proto-oncogenic factor in neoplastic tissues. In normal epidermis, we show that Meis1 is predominantly expressed in the bulge region of the hair follicles where multipotent adult stem cells reside, and that the number of these stem cells is reduced when Meis1 is deleted in the epidermal tissue of mice. Mice with epidermal deletion of Meis1 developed significantly fewer DMBA/TPA-induced benign and malignant tumors compared with wild-type mice, suggesting that Meis1 plays a role in both tumor development and malignant progression. This is consistent with the observation that Meis1 expression increases as tumors progress from benign papillomas to malignant carcinomas.

The discovery of hematopoietic stem cells (HSCs) provided a pioneering step in stem cell research. HSCs are a type of multipotent adult stem cell, characterized by their ability to self-renew and differentiate into erythrocyte (red blood cell) and leukocyte (white blood cell) cell lineages. In terms of function, these cells are responsible for the continual renewal of the erythrocytes, leukocytes, and platelets in the body through a process called hematopoiesis. They also play an important role in the formation of vital organs such as the liver and spleen during fetal development.. Format: Articles Subject: Processes ...

Multipotent stem cells are clonal cells that self-renew as well as differentiate to regenerate adult tissues. Whereas stem cells and their fates are known by unique genetic marker studies, the fate and function of these cells are best studied by their prospective isolation. This review is about the properties of various highly purified tissue-specific multipotent stem cells and purified oligolineage progenitors. We contend that unless the stem or progenitor cells in question have been purified to near homogeneity, one cannot know whether their generation of expected (or unexpected) progeny is a property of a known cell type. It is interesting that in the hematopoietic system the only long-term self-renewing cells in the stem and progenitors pool are the hematopoietic stem cells. This fact is discussed in the context of normal and leukemic hematopoiesis. ...

The NeiJing says, If the Sea of Marrow is abundant, vitality is good, the body feels light and agile, and the span of life will belong. The sea of marrow is the home for important stem cells in your body!. Stem-cell therapy is becoming the treatment option of choice for the regeneration of organs. Regenerative medicine is a field of medical research developing treatments to repair or re-grow specific tissue in the body. There is a rising body of studies that reveals the power of mesenchymal stem cells. Stem cells are multipotent stromal cells that can differentiate into a variety of cell types, [1] including osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells). This phenomenon has been documented in specific cells and tissues in living animals and their counterparts growing in laboratory tissue culture. Most Human Tissue has a rapid turnover rate. It is the availability of stem cells that assists in this process. However, with advanced ...

We have identified a subpopulation of stem cells within adult human BM, isolated at the single-cell level, that self-renew without loss of multipotency for more than 140 population doublings and exhibit the capacity for differentiation into cells of all 3 germ layers. Based on surface marker expression, these clonally expanded human BM-derived multipotent stem cells (hBMSCs) do not appear to belong to any previously described BM-derived stem cell population. Intramyocardial transplantation of hBMSCs after myocardial infarction resulted in robust engraftment of transplanted cells, which exhibited colocalization with markers of cardiomyocyte (CMC), EC, and smooth muscle cell (SMC) identity, consistent with differentiation of hBMSCs into multiple lineages in vivo. Furthermore, upregulation of paracrine factors including angiogenic cytokines and antiapoptotic factors, and proliferation of host ECs and CMCs, were observed in the hBMSC-transplanted hearts. Coculture of hBMSCs with CMCs, ECs, or SMCs ...

Multipotent mesenchymal stromal cells (MSCs) have gained considerable interest because of their potential use in the treatment of a variety of diseases and injuries. Although remarkable advancements have been made in clinical studies, substantial concerns still regard the safety of MSCs. Some evidence suggests that MSCs can spontaneously generate a population of cells with tumorigenic potential. Thus, studying the molecular mechanisms that control the proliferation of MSCs may be a necessary step toward the development of strategies for safe clinical practice. Ca2+ is a second messenger that mediates a wide range of cellular responses, including the regulation of cell proliferation, but little is known about its function in MSCs. The aim of this study was to investigate the effects of targeted Ca2+ buffering on MSCs proliferation in vitro. Here, we used an adenoviral (Ad) vector encoding the Ca2+ chelator protein parvalbumin (PV) fused to a nuclear exclusion signal (NES) and the Discosoma red

There is great interest in mesenchymal stromal cells (MSCs) for cell-therapy and tissue engineering approaches. MSCs are currently expanded in vitro in the presence of fetal calf serum (FCS); however, FCS raises concerns when used in clinical grade preparations. The aim of this study was to evaluate whether MSCs expanded in medium supplemented with platelet-lysate (PL), already shown to promote MSC growth, are endowed with biological properties appropriate for cell-therapy approaches. We confirm previously published data showing that MSCs expanded in either FCS or PL display comparable morphology, phenotype, and differentiation capacity, while PL-MSCs were superior in terms of clonogenic efficiency and proliferative capacity. We further extended these data by investigating the immune-regulatory effect of MSCs on the alloantigen-specific immune response in mixed lymphocyte culture (MLC). We found that MSCs-PL are comparable to MSCs-FCS in their capacity to: (i) decrease alloantigen-induced ...

The formation of complex ectodermal organs begins with multipotent stem cells that undergo many basic cellular events. During the formation of a complex organ, there are many factors that need to be considered such as patterning, size, and shape in order to maintain proper organ function. Feather development is a good model. The feather field must be patterned to establish how many feathers, the size must be determined, and the shape of the feather must be appropriate for its function. Canonical and non-canonical Wnt signaling has been implicated in many crucial steps in feather bud development.; Canonical Wnt signaling involves the stabilization and accumulation of beta-catenin, which is subsequently translocated to the nucleus. There, beta-catenin interacts with various coactivators including CREB-binding protein (CBP) and p300, which results in the expression of different genes downstream of beta-catenin/TCF that may direct cells towards a path of pluripotency or differentiation. One of the ...

However, unlike their terminally differentiated counterparts, these cells do not undergo programmed cell death during post-lactational remodeling of the gland. We previously demonstrated that upon transplantation into an epithelial-free mammary fat pad, PI-MECs exhibited two important features of multipotent mammary epithelial progenitors: a) self-renewal, and b) contribution to ductal and alveolar morphogenesis. In this new report, we introduce a new method to viably label PI-MECs. Using this methodology, we analyzed the requirement of ovarian ...

Neural stem cells in the subventricular zone (SVZ) continue to generate new neurons in the adult brain. SVZ cells exposed to EGF in culture grow to form neurospheres that are multipotent and self-renewing. We show here that the majority of these EGF-responsive cells are not derived from relatively quiescent stem cells in vivo, but from the highly mitotic, Dlx2(+), transit-amplifying C cells. When exposed to EGF, C cells downregulate Dlx2, arrest neuronal production, and become highly proliferative and invasive. Killing Dlx2(+) cells dramatically reduces the in vivo response to EGF and neurosphere formation in vitro. Furthermore, purified C cells are 53-fold enriched for neurosphere generation. We conclude that transit-amplifying cells retain stem cell competence under the influence of growth factors ...

However, it remains unclear whether β1-integrin has a role in cardiac progenitor cell (CPC) development. Here we show that a mesodermal deletion of β1-integrin decreases Isl1+ cell number in the second pharyngeal arch (PA2), where CPCs undergo renewal and expansion. Mesp1 lineage-specific mosaicism revealed that β1-integrin-deleted Isl1+ cells do not proliferate in the PA2. Consistently, β1-integrin-deleted ...

Researchers from the University of Toronto and The Ottawa Hospital were looking to see if mesenchymal stem cells (MSCs) might treat osteoporosis. MSCs are multipotent stromal cells that can differentiate into a variety of cell types, including: bone cells (osteoblasts), cartilage cells (chondrocytes), muscle cells (myocytes) and fat cells (adipocytes).. Faulty MSCs are the culprits behind osteoporosis; after injecting healthy MSCs into mice with the affliction that causes bones to become weak and brittle, researchers were hoping for a general increase in the mices bone health. Instead, they were surprised (and probably very excited) to discover after six months-a quarter of a mouses life span-that healthy, functioning bone had replaced the damaged osteoporotic bone. The bone structure in the little creatures, which had been severely compromised by osteoporosis, had been restored to a normal, healthy state!

We emphasize two aspects of these findings: (1) Wnts appear to function as an extracellular cue that instructively triggers neuronal differentiation; and (2) this effect of Wnts is dependent on the stage of development. In this Discussion, we address these aspects and their possible underlying mechanisms.. In general, two models can explain how the fate of an uncommitted precursor cell is influenced by extrinsic cues. In one model, extrinsic cues instruct multipotent precursor cells to commit to a particular lineage. In the other model, multipotent precursor cells choose their fate stochastically, and the proliferation and/or survival of specific lineage-restricted cells is then supported by extrinsic cues. For example, Pdgf treatment increases the size of the neuronal population in ...

Multipotent precursors are plastic cells that generate different, stable fates at the correct number, place and time, to allow tissue and organ formation. While fate determinants are known to trigger specific transcriptional programs, the molecular pathway driving the progression from multipotent precursors towards stable and specific identities remains poorly understood. Here we demonstrate that, in Drosophila neural precursors, the glial determinant glial cell missing (Gcm) acts as a time bomb and triggers its own degradation once the glial programme is stably activated. This requires a sequence of transcriptional and post-transcriptional loops, whereby a Gcm target first affects the expression and then acetylation of the fate determinant, thus controlling Gcm levels and stability over time. Defective homeostasis between the loops alters the neuron: glia ratio and freezes cells in an intermediate glial/neuronal phenotype. In sum, we identify an efficient strategy triggering cell identity, a ...

Multipotent stromal cells (MSCs) are an attractive cell source for bone and cartilage tissue repair strategies. However, the functional heterogeneity of MSCs derived from different donors and manufacturing conditions has limited clinical translation, emphasizing the need for improved methods to assess MSC chondrogenic capacity. We used functionally relevant morphological profiling to dynamically monitor emergent morphological phenotypes of chondrogenically induced MSC aggregates to identify morphological features indicative of MSC chondrogenesis. Toward this goal, we characterized the morphology of chondrogenically stimulated MSC aggregates from eight different human cell-lines at multiple passages and demonstrated that MSC aggregates exhibited unique morphological dynamics that were both cell line- and passage-dependent. This variation in 3D morphology was shown to be informative of long term MSC chondrogenesis based on multiple quantitative functional assays. We found that the specific ...

Rationale: We previously identified circulating mesoangioblasts (cMABs), a subset of mesenchymal stem cells that co-express KDR and Nkx2.5, from the patients undergoing open heart surgery. cMABs are capable of differentiating into endothelial cells, smooth muscle cells and cardiomyocytes. More recently, we demonstrated that hepatocyte growth factor (HGF) induces cMAB mobilization in rodents.. Objective: We therefore hypothesized that heparin induces cMAB mobilization by increasing the serum levels of HGF. We also explored the niche of cMABs.. Methods and Results: Patients undergoing cardiac catheterization were treated with an increasing dose of heparin at 100U/kg (n=7), 200 U/kg (n=11) and 300 U/kg (n=11). Serum HGF levels were determined by ELISA. Mononuclear cells (MNCs) were isolated from peripheral blood by Ficoll density gradient centrifugation and cultured on a fibronectin-coated dish, and the number of outgrowing colonies was counted. Consistent with previous studies, heparin ...

Multipotent mesenchymal stem cells (MSCs) are present in several tissue and may proliferate extensively differentiation of MSCs to mesodermal lineage For adipogenic differentiation, MSCs were seeded in 24 very well china at a focus of 2104 and cultured in adipogenesis differentiation moderate (Lifestyle Technology). S AZ 3146 i9000 yellowing was performed to identify gathered calcium supplement. For chondrogenic difference, a total of 8104 MSCs in 20 m of lifestyle moderate had been plated in the middle of 24 well china. After 3 hours incubation, chondrogenesis difference moderate was supplied (Lifestyle Technology). After 14 or 21 times of lifestyle, cells had been set in 4% paraformaldehyde. After that, Alcian Blue Yellowing was performed, which discovered sulfated proteoglycan wealthy matrix.

Tooth root pulp is home to two types of prized stem cells. The first, pluripotent stem cells, have the ability to become any cell in the organism from which theyre drawn. The second, multipotent stem cells, transform into specific types of cells within that organism.. Knowing where to find these cells was one thing. Recovering them, the researchers knew, would be another.. Common methods for extracting root pulp involve drilling into, removing the top of, or shattering the tooth. Each method has its detriments, Dr. Mah said, all of which lead to a low stem-cell recovery rate: damaging heat from drilling, corrosive elements in the water teeth are rinsed in, contaminating enamel particulates, and more. So the researchers sought to discover how to extract pulp in a manner that consistently produced a higher yield.. Initially, the answer seemed simple: crack the tooth in half like a nut and remove the pulp, Dr. Mah said.. Unfortunately, teeth have irregular surfaces and non-uniform shapes, so ...
