(A) ALP staining of N-GMSCs and H-GMSCs. (B) ALP activity in N-GMSCs and H-GMSCs did not differ (n=5, P<0.1; Student’s t test). (C) Alizarin red S staining of N-GMSCs and H-GMSCs under osteogenic induction. (D) Calcium concentrations in N-GMSCs were higher than in H-GMSCs (n=5, P<0.01; Student’s t test). (E) Oil red O staining of N-GMSCs and H-GMSCs under adipogenic induction (scale bar=200 μm).
