Representative H&E stained renal cortex from animals exposed to RA, hyperoxia (50% O2) or neonatal IH (8 episodes/day) at P14 or P21. P21–7D groups were exposed to hyperoxia or neonatal IH from P0-P7, then placed in RA from P7-P21. P21–14D groups were exposed to hyperoxia or neonatal IH from P0-P14, then placed in RA from P14-P21. Data shows severe damage in the groups recovering from 8 IH episodes per day (arrows). Images are 20X magnification (scale bar is 50 μm)
