(A) Representative images of flat-mounted retinas from WT rats and hCRP-Tg rats with OIR or constant room air at postnatal days 14 (P14) and 18 (P18). White stars indicate non-perfusion areas. White arrows indicate neovascular area. Scale bar = 300 μm. (B) The percentage of the non-perfusion area in the flat-mounted retinas in WT rats and hCRP-Tg rats with OIR at P14. (C) The percentage of the neovascular area in the flat-mounted retina in WT rats and hCRP-Tg rats with OIR at P18. Data were presented as mean ± SEM (n=6). *P<0.05, **P<0.01.
