To induce endothelial cell, canine bone marrow-derived mesenchymal stem cells (MSCs) were separated from bone marrow by density gradient centrifugation. The isolated MSCs were induced to form endothelial-like cell in the presence of vascular endothelial growth factor (VEGF), endothelial growth factor (EGF) and so on. These results showed that the cells uniformly took on a cobblestone morphology under the light microscope, and cell nucleolus was in the middle of the cells. The cells displayed Weibel-Palade bodies under the transmission electron microscope. vWF, a specific marker of endothelial cell was positive in the cells. The above results demonstrate that MSCs may be differentiated into endothelial cells in vitro.
