Fig. 4 — Chondrogenesis differentiation. Comparison of cBMMSCs and cADMSCs. a chondrogenesis as detected by alcian blue staining at d 14 after induction (a) cBMMSCs^Low, 5X (b) cBMMSCs^High, 5X (c) cADMSCs^Low, 5X (d) cADMSCs^High, 5X. b Graph representing normalized alcian blue staining (indicating the GAG content in the chondrocyte differentiated cBMMSCs and cADMSCs from low and high passages). Dotted line indicates the GAG content in undifferentiated cells normalized to 100. Significantly different values (P < 0.05) represent the comparison between the three time points within a specific group. Identical letters indicate no significance
