In addition, studies in animal models suggest that the mesenchymal stem cell commitment into pre-adipocytes can already occur during fetal development and perinatal life. Since the number of pre-adipocytes and mature adipocytes is lower in normal subjects than in obese subjects, changes in the prenatal maturational process may play a role in the pathogenesis of obesity and metabolic-associated diseases. Hyperglycemia during pregnancy is related to an increased risk of obesity, early onset of metabolic syndrome and type 2 diabetes in the offspring. For this reason it would be useful to investigate how the perinatal environment may affect fetal mesenchymal stem cells, especially in deregulated gestational diabetes, where the fetal environment is modified in terms of hormone levels and nutrition. Therefore, we have compared Wharton’s jelly mesenchymal stem cells (WJ-MSC) obtained from umbilical cord of both healthy and diabetic mothers, in order to better understand the mechanisms involved in metabolic diseases in offspring of diabetic mothers. Results indicate that WJ-MSC from diabetic mothers display, in contrast to cells from healthy mothers, a higher ability to differentiate towards the adipogenic lineage. This suggests that the diabetic uterine environment may be responsible for a “pre-commitment” that could give rise in the post natal life to an alteration of adipocyte production upon an incorrect diet style, which in turn would produce obesity.","PeriodicalId":88761,"journal":{"name":"The open tissue engineering and regenerative medicine journal","volume":"4 1","pages":"103-111"},"PeriodicalIF":0.0,"publicationDate":"2011-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68108601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to its wide- spread availability, the umbilical cord may be an excellent alternative source of cells for regenerative medicine. Anatomically, umbilical cord tissue is constituted of several different parts, and, accordingly, immunostaining of cord tissue sections revealed differential distribution of several markers and extracellular matrix, distinguishing the various layers. Wharton's jelly is the major component filling the inner part of the umbilical cord tissue, and it has been commonly used as a source of obtaining multipotent cells from umbilical cord. We recently reported isolating mesenchymal stem cells from cord lining membrane (sub-amnion). However, because of several anatomically distinct zones found in the umbilical cord, isolated multipotent cells sometimes show heterogeneity. In addition, differences in isolation technique may lead to further variation. In this review, we discuss the similarities and differences between the cells derived from each sub-region, including sub-amnion as recently reported by us.

In particular, research in the last few years has delineated the key features of perinatal stem cells derived from fetus-associated tissues. These cells show multiple differentiation potential, can be easily expanded ex vivo, and raise no ethical concerns as regards their use. Several reports indicate that cells isolated from Wharton's jelly (WJ), the main component of umbilical cord extracellular matrix, are multipotent stem cells that express markers shared by other mesenchymal stem cells (MSC) and give rise to different mature cell types belonging to all three germ layers. Moreover, WJ-MSC display promising hypoimmunogenic and immunomodulatory properties, since they express molecules able to modulate NK cells and expand regulatory T-cell populations. In this review, we focus on the use of perinatal stem cells for regenerative medicine aimed at cartilage repair and regeneration. Cartilage is a specialized connective tissue which has poor regeneration and self-repair capacity in vivo. Traumatic injury or autoimmune processes are among the main causes of cartilage damage and degeneration, for which new hope comes from tissue engineering using stem cells which have undergone chondrocyte-like differentiation. We analyze the in vitro and in vivo data on the use of perinatal stem cells, in particular WJ-MSC, for cartilage regenerative medicine. The high variability of cell sources, the use of different types of scaffolds and matrixes, and the administration of several combinations of growth factors clearly point out the need for further research to optimize this cellular therapy approach and translate the results obtained from bench to clinic.","PeriodicalId":88761,"journal":{"name":"The open tissue engineering and regenerative medicine journal","volume":"4 1","pages":"72-81"},"PeriodicalIF":0.0,"publicationDate":"2011-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68108547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Animals: 48 Nude rats (Crl:NIH-Foxn1 rnu ) of 200-250 g weight were used. Procedure: The Achilles tendon was exposed by blunt dissection and, using a 30G needle, 30 µl of either a mixture of cells (2 x10 5 ) and collagenase, or collagenase alone, was injected close to the musculotendinous junction in the direction of the osteotendinous junction. Results: Harvested tendons showed the presence of HUCPVCs at the site of injury, whose morphology changed from ovoid to elongated over the 30 post-injury experimental time period. Human genes for collagen type 1 and β-actin were expressed at all time points and there was also a significant increase in tendon tensile strength and stiffness by 30 days post-injury in the experimental group. Conclusion: HUCPVCs facilitated regeneration in our model through changes in collagen organization; cell shape and orientation; and increase in mechanical properties over those of the untreated controls. Clinical Relevance: Cell therapy has been shown to be effective in treating tendon injuries, especially in equines. We have recently isolated a mesenchymal cell population from equine umbilical cords that is analogous to a well-characterized HUCPVC population. Our results indicate that HUCPVCs are a putative cell source for treating tendon injuries; and this model could explain the benefits of using analogous cells in equines.","PeriodicalId":88761,"journal":{"name":"The open tissue engineering and regenerative medicine journal","volume":"4 1","pages":"112-119"},"PeriodicalIF":0.0,"publicationDate":"2011-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68108612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The homing ability of human and rat UCMSC to inflammatory tissues, including cancer tissues, further confers upon these cells the potential for targeted cancer therapy. Our previous studies demonstrated that un-engineered human and rat UCMSC significantly attenuated the growth of multiple cancer cell lines in vivo and in vitro through multiple mechanisms. We have also demonstrated that these cells can be engineered to express cytotoxic cytokines before being delivered to the tumor and can be preloaded with nanoparticle payloads and attenuate tumors after homing to them.

Thus, several stromal substitutes of bone marrow mesenchymal stem cells (BMMSCs) are being considered for regenerative therapy. Wharton's jelly mesenchymal stem cells (WJMSCs) seem to be the most promising alternative because of easy donor accessibility, high proliferative capacity and greater sample to sample identity. Recent in vitro and in vivo evidences also support the usage of WJMSCs in tissue repair and regeneration. Key to these observations is secretion of trophic and immune regulatory factors, which aid repair, and resolution of injury. In order to extrapolate these results for clinical usage key questions that need to be addressed are: extrapolation of \"allogeneic\" transplantation ability of BMMSCs to WJMSCs, survival of allogeneic/xenogeneic WJMSCs in transplantation scenario and actual mechanisms of immune-modulation in an \"inflammatory\" setting. This review focuses on comparing the in vitro and in vivo studies on immune regulatory properties of WJMSCs and BMMSCs and speculates the usage of WJMSCs for immuno-modulation in a disease scenario. Despite commonalities, different tissue-derived MSCs are reported to have unique gene expression signatures. We would evaluate whether WJMSCs have unique inherent properties, owing to their bio-distribution and primitiveness, as compared to BMMSCs. Further, we debate whether these differences remain conserved on in vitro propagation and impact the immune properties of WJMSCs and speculate the pros and cons of using WJMSCs for allogeneic transplantation.

The high heterogeneity of extraction, culture and analysis procedures hinder the ability to precisely identify UC stromal cells.
