Introduction: Although mesenchymal stem cells (MSCs) from different sources share many similar characteristics, they also exhibit individual properties. In this study, we compared MSCs derived from Wharton's jelly in the umbilical cord with those derived from the decidual basalis in the maternal part of the placenta to better understand the similarities and differences between these two cell types. Method: The morphology, immunophenotype (as assessed using flow cytometry), and multi-lineage differentiation potential were analyzed. Karyotype analysis was carried out to determine the origin of the MSCs. Growth kinetics were evaluated using analysis of the population doubling time and cell cycle. Immunosuppressive function was analyzed using mixed lymphocyte culture. Results: MSCs from Wharton's jelly and the decidua basalis exhibited similar morphology, immunophenotype, and differentiation potential to osteogenesis and adipogenesis. The percentage of MSCs in the G0/G1 phase was higher in the case of Wharton's jelly than in the case of the decidua basalis (P < 0.05). Decidual MSCs displayed more remarkable immunosuppressive effects on phytohemagglutinin-stimulated T-cell proliferation (P < 0.05). Conclusion: MSCs from both sources had similar basic biological properties, but decidual MSCs had slower proliferation and stronger immunosuppressive function. © 2015 Chen et al. Source
