Fig. 4From: Increasing transforming growth factor-beta concentrations with age decrease apelin in the rat rotator cuffEffect of TGF-β on apelin mRNA expression. Effect of TGF-β on Apelin gene expression in cultured rotator cuff-derived cells. Rotator cuff-derived cells were stimulated with 0 (control) and 10 ng/mL recombinant TGF-β. Gene expression was compared between cells that received TGF-β stimulation for 6 and 24 h and the control group (0 ng/mL TGF-β). Data indicate mean ± SE (n = 9). * p < 0.05, compared to controlBack to article page
