Retinal histopathology and mtDNA damage in ZDF rats: (a) trypsin-digested retinal microvessels from 12- and 40-week-old ZDF rats were stained with periodic acid Schiff-hematoxylin for acellular capillaries and the arrow indicates an acellular capillary; the picture shows microvasculature from 12- and 40-week-old ZDF rats and 40-week-old lean rats; (b) mtDNA damage in the retina was determined by extended-length PCR. Values are represented as mean ± SD from five to seven rats per group; *P < 0.05 compared with age-matched lean rats. Measurements were performed on five to six rats in each group.
