Four of them: sex of the donor (p = 0.006), presence of osteoporosis (p < 0.001), number of CD146+ cells (p = 0.009), and number of ALP+ cells (p = 0.02) are in common with the findings for OB differentiation but except for the ALP+ expression; these have the opposite effect on adipocyte formation. The gene discussed is MCAM; the disease is osteoporosis.
