Figure Lengend Snippet: Refi - 10 reduces pathological neovascularization in oxygen-induced retinopathy (OIR) mice. ( A ) Refi-10 was administered intraperitoneally at P13, and retinas were analyzed at P17. ( B ) Analysis of retinal vasculature. ( a ) Representative IB4-stained whole-mount retinas from normal, OIR, OIR + Refi-10 (25 mg/kg), and OIR + Refi-10 (50 mg/kg) mice at P17. Avascular areas were circled in white . ( b ) Enlarged views of the boxed regions in a . Yellow arrows indicate vascular tufts. ( c ) Neovascularization regions were highlighted in white by ImageJ software. ( d , e ) The quantification of neovascular area and avascular area for each group. Scale bars = 1000 µm. ( C ) Representative H&E staining of retinal sections and quantification of endothelial cell nuclei anterior to the inner limiting membrane. Scale bars = 500 µm. Data are presented as mean ± SD ( n = 6 mice per group; * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001).
Article Snippet: Then, they were incubated with IB4 (1:100, DL-1208-.5; Vector Laboratories, USA) overnight at 4°C.
