Rapamycin Inhibits the Growth and Collagen Production of Fibroblasts Derived from Human Urethral Scar Tissue

Figure 3

Rapamycin decreases collagen production by FHUS. Collagen production by FHUS, based on measurements of hydroxyproline levels (enzyme-linked immunosorbent assay). FHUS were exposed to six different concentrations of rapamycin (0, 10, 20, 40, 80, or 160 ng/ml) for 48 h. (a) Concentration-dependent effects of rapamycin on total collagen production. (b) Concentration-dependent effects of rapamycin on collagen production per 105 cells. Data shown as mean ± standard deviation ( cell lines from four patients). , versus the control group (0 ng/ml rapamycin).
