Capillary network formation by endothelial cells differentiated from human bone marrow mesenchymal stem cells

ABSTRACT

Human bone marrow derived mesenchymal stem cells [HBMSCs] have the potential to differentiate into cells such as adipocyte, osteocyte, hepatocyte and endothelial cells. In this study, the differentiation of hBMSCs into endothelial like-cells was induced in presence of vascular endothelial growth factor [VEGF] and insulin-like growth factor [IGF-1]. The differentiated endothelial cells were examined for their ability to express VEGF receptor-2 [VEGFR2] and von willebrand factor [vWF]. Then the cells were adopted to grow and develop capillary network in a semisolid gel matrix in vitro. The capillary network formation in a well of 24-well plate was found to be 85% in presence of VEGF [50ng/ml] and IGF-1 [20ng/ml] of the culture media. These data may suggest that the expression of endothelial markers in endothelial like-cells derived from hBMSCs is associated with their ability to form capillaries
