Neovascularization leakage areas analysis (IOD/Area, comparison in 5 groups). a Neovascularization leakage areas analysis at 1 h. b Neovascularization leakage areas analysis at 1d. c Neovascularization leakage areas analysis at 3d. d Neovascularization leakage areas analysis at 5d. ^*P < 0.05, ^**P < 0.01 as compared with Blank; ^##P < 0.01, ^###P < 0.001 as compared with OIR + NC. IOD: integral optical density. Blank: blank control group (age-matched rats kept in constant normoxia with non-intravitreal injection); OIR + NC (negative control group): oxygen-induced retinopathy (OIR) rats with empty-lentivirus intravitreal injection; OIR + ES-LV: OIR rats with endostatin-lentivirus intravitreal injection; OIR + EPCs: OIR rats with EPCs intravitreal injection; OIR + ES-LV-EPCs: OIR rats with endostatin-lentivirus-EPCs intravitreal injection
