CD146 expression on mesenchymal stem cells is associated with their vascular smooth muscle commitment.

ABSTRACT: Bone marrow mesenchymal stem cells (MSCs) are plastic adherent cells that can differentiate into various tissue lineages, including osteoblasts, adipocytes and chondrocytes. However, this progenitor property is not shared by all cells within the MSC population. In addition, MSCs vary in their proliferation capacity and expression of markers. Because of heterogeneity of CD146 expression in the MSC population, we compared CD146(-/Low) and CD146(High) cells under clonal conditions and after sorting of the non-clonal cell population to determine whether this expression is associated with specific functions. CD146(-/Low) and CD146(High) bone marrow MSCs did not differ in colony-forming unit-fibroblast number, osteogenic, adipogenic and chondrogenic differentiation or in vitro haematopoietic-sup
