Abstract: | AIM: To investigate the isolation, purification, expansion and multilineage differentiation of mesenchymal stem cells (MSCs) derived from human umbilical cord vein in vitro.METHODS: By 1% collagenase Ⅱ digestion, endothelial cells were isolated from human umbilical cord vein and cultured in IMDM medium.The morphology of the cells was observed by Wright’s staining and electron microscope.Cell cycle and immunophenotype were investigated by flow cytometry.Assays of adipogenic and osteogenic differentiation were performed in vitro.von Kossa staining, Oil Red O staining and mRNA expression of osteopontin and lipoprotein lipase were studied in the induced cells.RESULTS: The cells from the cord vein displayed a fibroblast-like morphology adhering to the culture plate.FACS showed that the cells expressed several MSCs-related antigens such as CD29, CD44 and CD105, while CD13, CD31, CD45, CD34, and HLA-DR were negative.Adipocyte and osteocyte differentiation were induced successfully.CONCLUSION: The morphology, growth characteristics, immunophenotype and pluripotentiality of the MSCs from human umbilical cord vein are similar to the MSCs from bone marrow (BM).They could potentially be an excellent source of MSCs for experiments and clinics. |
