Fig. 1. — Concentrations of total and activated TGF-β1 and -β2 protein in the vitreous. (A) Concentrations of total TGF-β1 in the vitreal samples were measured by ELISA (MH, n = 6; RRD, n = 6; PDR, n = 12; and PVR, n = 11). (B and C) Concentrations of total TGF-β2 (B) and activated TGF-β2 (C). (MH, n = 6; RRD, n = 6; PDR, n = 12; and PVR, n = 12). *: PDR vs. MH, P = 0.0007; PDR vs. RRD, P = 0.003; PVR vs. MH, P = 0.002; and PVR vs. RRD, P = 0.049. **: PDR vs. MH, P = 0.005; PDR vs. RRD, P = 0.015; PVR vs. MH, P = 0.002; and PVR vs. RRD, P = 0.005 (Mann-Whitney U-test). (D) Correlation between the concentrations of total and activated TGF-β2 (r = 0.37, P = 0.026).
