Abstract:
BACKGROUND: The placental tissue structure is complex, including the amniotic membrane, chorion, and decidua from the mother. Mesenchymal stem cells derived from different tissues of the same placenta have been reported to have similar biological characteristics. To date, there is no study regarding quantitative comparison of differentiation potential and immunomodulatory function of mesenchymal stem cells derived from different tissues of human placenta. OBJECTIVE: To investigate the biological characteristics including differentiation potential and immunomodulatory function of mesenchymal stem cells derived from different tissues of human placenta. METHODS: The amnion-, chorion-, and decidua-derived mesenchymal stem cells were isolated from the placental tissue of a baby boy by enzymatic digestion method. The biological characteristics of these three kinds of mesenchymal stem cells were systematically investigated including cell morphology, immunophenotypes, karyotypeanalysis, adipogenic and osteogenic differentiation potential, and Treg cells proliferation capacity. RESULTS AND CONCLUSION: All three kinds of mesenchymal stem cells showed fibroblast-like morphology and expressed the surface markers of mesenchymal stem cells with high expressions of CD73, CD90 and CD105, as well as low expressions of CD14, CD19, CD34, CD45 and HLA-DR. The karyotypes of the amnion-and chorion-derived mesenchymal stem cells were the same as the fetus, and decidua-derived mesenchymal stem cells had the same karyotype as the mother. There were significant differences in adipogenic differentiation capacity between three kinds of mesenchymal stem cells (amnion-derived mesenchymal stem cells> chorion-derived mesenchymal stem cells> decidua-derived mesenchymal stem cells; P < 0.05). In contrast, the osteogenic differentiation capacity of amnion-derived mesenchymal stem cells was remarkably higher than that of decidua-derived mesenchymal stem cells (P < 0.05). The amnion-and chorion-derived mesenchymal stem cells had the higher potential of Treg cell proliferation induction than decidua-derived mesenchymal stem cells. These findings indicate that three sources of human placenta-derived mesenchymal stem cells have different karyotypes, adipogenic and osteogenic differentiation potential, and immunomodulatory capability, providing a variety of ideal seed cell sources for disease treatment.
