چکیده
Co-culture of bone forming cells and endothelial cells to induce pre-vascularization is one of the strategies used to solve the insufficient vascularization problem in bone tissue engineering attempts. In the study, primary cells isolated from 2 different tissues of the same animal, rat bone marrow stem cells (RBMSCs) and rat aortic endothelial cells (RAECs) were co-cultured to study the effects of co-culturing on both osteogenesis and angiogenesis. The formation of tube like structure in 2D culture was observed for the first time in the literature by the co-culture of primary cells from the same animal and also osteogenesis and angiogenesis were investigated at the same time by using this co-culture system. Co-cultured cells mineralized and formed microvasculature beginning from 14days of incubation. After 28days of incubation in the osteogenic medium, expression of osteogenic genes in co-cultures was significantly upregulated compared to RBMSCs cultured alone. These results suggest that the co-culture of endothelial cells with mesenchymal stem cells induces both osteogenesis and angiogenesis.

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 exam...
متن کاملStudy of Chondrogenic Effects of Chondrocytes Cocultured With Murine Bone Marrow-Derived Mesenchymal Stem Cells
Purpose: Co-culture systems of marrow derived mesenchymal stem cells (mMSCs) with mature chondrocytes have theoretically been considered as a putative way of MSCs chondrogenic differentiation. MSCs differentiated in this system could be used for transplantation purpose without of any need to their purification since the cells with which MSCs are co cultured are native cartilage cells. Despite o...
