ABSTRACT
<p><b>OBJECTIVE</b>To study differentiation of human bone marrow-derived mesenchymal stem cells (BDMSC) into blood vessel endothelial cells for ideal cell origin of complex organ tissue engineering vascularization and injured tissue repairing by cell transplantation.</p><p><b>METHOD</b>After different days of induction with vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in 3D fibrin-gels and matrigel, BDMSC and angiogenesis were determined by the utilization of morphological observation, tissue section and CD34, CD31, vascular endothelial growth factor receptor-1 (VEGFR-1, Flt-1), VEGFR-2 (Flk-1), and vWF that were special for blood vessel endothelial cells.</p><p><b>RESULT</b>After 3D-cultured and induced with VEGF and bFGF in vitro in fibrin-gels and matrigel for 3-21 days, BDMSC expressed CD34, CD31, Flt-1, Flk-1, and vWF came into vessel-like configuration.</p><p><b>CONCLUSION</b>VEGF, bFGF as well as Flt-1 and Flk-1, expressed by BDMSC, may form a feasible microenviroment after induction and play an important role during processes of blood vessel endothelial cell differentiation and vessel-like configuration forming of BDMSC. Mesenchymal stem cells may be applied to tissue engineering vascularization and injured tissue repairing by cell transplantation.</p>
