Figure 5: Immunofluorescence results of the retina of mice at the age of 17 days. The result of representative immunofluorescence images. Scale bars: 50 μm. White arrows indicate red cells representing the expression of VEGF. Blue cells represent the nuclei of cells in the retina. Data are expressed as the mean ± SD (n = 15 mice per group). **P < 0.01 (Mann-Whitney U test). DAPI: 4′,6-Diamidino-2-phenylindole; OIR-C: oxygen induced retinopathy, control eye; OIR-T: oxygen induced retinopathy eye injected intravitreally with MEG3 overexpression lentivirus; VEGF: vascular endothelial growth factor.
