Morphological characteristics of lipocytes, osteoblasts, and chondrocytes induced to differentiate from bone marrow mesenchymal stem cells (BMMSCs), skin mesenchymal stem cells (SMSCs), and skin fibroblasts. (a) Lipocytes induced to differentiate from BMMSCs. (b) Lipocytes induced to differentiate from SMSCs. (c) Skin fibroblasts maintained the original cell morphology and were not stained by oil red O after induction to lipocytes. (d) Osteoblasts induced to differentiate from BMMSCs. (e) Osteoblasts induced to differentiate from SMSCs. (f) Skin fibroblasts maintained the original cell morphology and were not stained by alizarin red solution after induction to osteoblasts. (g) Chondrocyte pellet induced to differentiate from BMMSCs. (h) Chondrocyte pellet induced to differentiate from SMSCs. (i) Skin fibroblast micromasses were not stained by toluidine blue after induction to chondrocytes. Scale bar: 50 μm.
