Comparison of Alizarin-Red Staining between OASC2 and BMSC in growth medium and chondrogenic induction medium. a In OASC2, Alizarin Red Staining was visible in chondrogenesis medium (Chondro.) as early as day 7 and presented a progressive increase in the calcium content in the accumulated matrix by day 14. b Quantification of Alizarin Red staining in OASC2 by ImageJ software. c Minimal Alizarin Red staining in BMSC when cultured in basal medium (Growth) or chondrogenesis medium (Chondro.) by day 14. d Quantification of Alizarin red staining in BMSC by ImageJ software. Data are presented as mean ± SD from at least 3 sample images for each group. **: p ≤ 0.01, relative to indicated control groups respectively
