Protein expression of human satellite cells. A: Representative image of hTERT, p53, p21 and p16 expression in human satellite cells from patients suffering from rheumatoid arthritis (N = 4) or osteoarthritis (N = 8). Actin and tubulin expression was used for normalization. B: Normalized average protein expression and 95% confidence interval of hTERT, p53, p21 and p16.
