Activation of Cannabinoid Receptor 2 Enhances Osteogenic Differentiation of Bone Marrow Derived Mesenchymal Stem Cells

Figure 5

Expression of cannabinoid receptor 2 in healthy and osteoporotic patients. (a) Immunohistochemistry shows presence of CB₂ receptor in the bone marrow tissue of healthy donor, and absence in osteoporotic patients. Bar = 100 μm. Arrowheads indicate the positively stained cells. (b) Real-time PCR analysis of CNR2 bone morrow tissue of healthy donor and osteoporotic donor ().
