Potential Osteoinductive Effects of Calcitriol on the m-RNA of Mesenchymal Stem Cells Derived from Human Alveolar Periosteum

Figure 1

Differentiation study. (a) Mesenchymal stem cells (MSCs) were spindle-shaped with irregular processes and firmly attached to the culture plate after 1–3 days of primary culture (asterisk). Under in vitro culture conditions, MSCs were subpassaged and differentiated into (b) osteoblasts (asterisk, black, von Kossa staining), (c) chondrocytes (asterisk, blue, Alcian blue staining), and (d) adipocytes (asterisk, pink, Oil Red O staining).
