Fig. 3From: Increasing transforming growth factor-beta concentrations with age decrease apelin in the rat rotator cuffTGF-β gene expression and TGF-β protein concentration in the rotator cuff. (A) Relative Tgfb gene expression in rotator cuff cells extracted from young (12 weeks), adult (24 weeks), and old (48 weeks) rats. (B) TGF-β protein concentration in rotator cuff cells from young (12 weeks), adult (24 weeks), and old (48 weeks) rats. Data indicate mean ± SE (n = 9). * p < 0.05, among three groupsBack to article page
