مقايسه استحصال و موفقيت در تخليص سلولهاي بنيادي مزانشيمي از دو منبع مغز استخوان و بافت چربي انسان

Introduction: Mesenchymal stem cells (MSCs) exhibit multiple beneficial properties in treatment of various diseases through their differentiation capacity and secretion of paracrine signals. Therefore, using MSCs as a tool for cell therapy rely on the ability of harvesting a sufficient number of cells in a short time. Methods: In this study, MSCs derived from bone marrow (BM) and adipose tissue (AD) were investigated in terms of success rate of culture and cell yields. To ensure that the isolated cells are MSCs, adipogenic and osteogenic differentiation study were performed by Oil Red O, Alizarin Red S and Alkaline Phosphatase assay, and specific surface markers expression examined by flow cytometry. Results: The results showed that successful culture's rate of AD-MSCs were superior to BM-MSCs. AD-MSCs reached to confluency and passage in a shorter time (faster) and produced further amount of cells at a defined time. It was also demonstrated that the derivation of MSCs from adipose tissue were completely reproducible and not donor dependent rather than BM-MSCs. Conclusion: In conclusion, with our protocol, adipose tissues are proposed the more appropriate source for derivation of MSCs in terms of percentage of cells successfully isolated and subsequent purification as compared to bone marrow.
