Protein expression of aggrecan and collagen-I in ADMSCs under the IVD-like chemical conditions. Western blot analysis of aggrecan and collagen-I protein levels in ADMSCs cultured for 1 week or 2 weeks under IVD-like chemical conditions. Shown were representative blots from six independent experiments with similar results. β-actin served as loading control. Statistically significant differences were indicated with asterisks, ** P < 0.01, *** P < 0.001.
