Figure 2: Retinal angiographs in mice at the age of 17 days. (A) Immunofluorescence images of the retina of P17 mice (blue arrows indicate a vascular area, yellow arrows indicate neovascular clusters, scale bars: 50 μm). (B) The clock hour scores of neovascularization. (C) The area of neovascularization. Data are expressed as the mean ± SD (n = 15 mice per group). **P < 0.01 (Mann-Whitney U test). OIR-C: Oxygen-induced retinopathy, control eye; OIR-T: oxygen-induced retinopathy eye injected intravitreally with MEG3 overexpression lentivirus.
