摘要

Placenta-derived stem cells (PDSCs) have gained interest as an alternative source of stem cells for regenerative medicine because of their potential for self-renewal and differentiation and their immunomodulatory properties. Although many studies have characterized various PDSCs biologically, the properties of the self-renewal and differentiation potential among PDSCs have not yet been directly compared. We consider the characterization of chorionic-plate-derived mesenchymal stem cells (CP-MSCs) and Wharton's jelly-derived mesenchymal stem cells (WJ-MSCs) among various PDSCs and the assessment of their differentiation potential to be important for future studies into the applicability and effectiveness of PDSCs in cell therapy. In the present study, the capacities for self-renewal and multipotent differentiation of CP-MSCs and WJ-MSC isolated from normal term placentas were compared. CP-MSCs and WJ-MSCs expressed mRNAs for the pluripotent stem cell markers Oct-4, Nanog, and Sox-2. Additionally, HLA-G for immunomodulatory effects was found to be expressed at both the mRNA and protein levels in both cell types. The CP-MSCs and WJ-MSCs also had the capacities to differentiate into cells of mesodermal (adipogenic and osteogenic) and endodermal (hepatogenic) lineages. Expression of adipogenesis-related genes was higher in CP-MSCs than in WJ-MSCs, whereas WJ-MSCs accumulated more mineralized matrix than CP-MSCs. The WJ-MSCs expressed more of CYP3A4 mRNA, a marker for mature hepatocytes, than CP-MSCs. Thus, we propose that CP-MSCs and WJ-MSCs are useful sources of cells for appropriate clinical applications in the treatment of various degenerative diseases.
