Özet

Pericytes are CD146+ perivascular cells (PCs) that have multipotential differentiation capacity as mesenchymal stem cells. Beside their crucial roles in vascular development and blood flow regulation, they have ability to differentiate into vascular cell types in vivo. These properties make pericytes preferred cells in the field of vascular tissue engineering. Culture medium for in vitro differentiation of pericytes to vascular smooth muscle cells (SMCs) has not been defined yet. The aim of this study is to try different culture media for SMC differentiation of CD146+ PCs. For this purpose, CD146+ PCs were isolated from human umbilical cord vein. Then they were characterized by immunofluorescence staining and flow cytometric analysis. Three different culture media including; (1) Transforming growth factor beta 1 (TGF-beta 1)+ bone morphogenic protein 4, (2) TGF-beta 1+ l-ascorbic acid (l-AA) and (3) Horse serum, were compared for differentiation of CD146+ PCs to SMCs by IFS and real time polymerase chain reaction. As a result, in the case of SMC differentiation of CD146+ PCs, second culture medium including TGF-beta 1 and l-AA was found to be more effective than other two media. These results are important for establishing proper culture conditions for in vitro SMC differentiation of CD146+ PCs.
