Abstract

The present study was designed to test whether Rho-kinase (ROCK) specific inhibitor fasudil (HA-1077) could contribute to migration and vasculogenesis of endothelial cells differentiated from rat bone marrow mesenchymal stem cells (rBMSCs) in vitro. rBMSCs were separated by gradient centrifugation on lymphocytes separation medium from bone marrow of Sprague-Dawley rats, and were cultured, purified and expanded in vitro. Cells of passage 2 to 3 were induced to differentiate into endothelial lineage cells by HG-DMEM plus EGM-2. These cells were identified as endothelial cells with positive factor VIII and Ulex europaeus agglutinin-1 expressions and DiI-Ac-LDL uptake. HA-1077 and VEGF synergistically promoted cell migration, especially in response to transwell chamber assay. When the cells were cultured on ECMatrixTM, they showed cellular protrusions and/or cords of aligned cells resembling primitive capillary-like structures at 8 to 12 h of incubation. HA-1077 promoted cell migration and formation of capillary-like tubes. The length of the total capillary tubes was longer than that in the control group (P<0.05). When the cells were exposed to a combination of VEGF and HA-1077, the number of the capillary-like networks and the stability of tube increased. The results obtained suggest that HA-1077 can promote migration and vasculogenesis of endothelial cells differentiated from rBMSCs in vitro.
