Figure 4From: Homing and reparative effect of intra-articular injection of autologus mesenchymal stem cells in osteoarthritic animal model (a) Control undifferentiated MSCs showed neither staining with Alzarin red (special stain for differentiated MSCs into osteoblasts) nor Alcian blue (special stain for differentiated MSCs into chondrocytes); (b) Osteogenic differentiation of these cells shows the presence of alizarin stained calcium deposits in MSCs-BM; (c) Chondrogenic differentiation of MSCs-BM shows the presence of Alcian blue stained of differentiated cells. All these images are at a magnification of 20X.Back to article page
