Abstract
BACKGROUND: To compare the roles of adipose and bone marrow derived mesenchymal stem cells (AMSCs and BMSCs) in multiple differentiation capacity to provide a theoretical basis for stem cell transplantation. METHODS: We isolated bone marrow and adipose derived mesenchymal stem cells and compared their phenotype, cell doubling time, the secretion of factors, and the ability of multi-differentiation. RESULTS: BMSCs and AMSCs were similar in cell phenotype and the differences existed only between the expression of CD106. The proliferation rate of AMSCs was faster than of BMSCs (doubling time 28h vs. 39h) and the capacity to suppress T cell proliferation and activation was weakened in AMSCs. In addition, both sources of cells were able to differentiate into bone, fat, and cartilage which proved their stem cell properties. CONCLUSIONS: Cell origin and abundance were decisive factors in stem cell applications and with the same premise as for AMSCs and BMSCs, adipose tissue is a more promising source of stem cells.
