Figure 5
The ratio of E/P and number of acellular strands and the morphological changes between the two groups in PAS staining of retinal tissue (magnification, ×400). (a)–(e) were the PAS staining of the diabetes group. (f)–(j) represented PAS staining in the normal group at corresponding time points. (k, l) represented the ratio of E/P and acellular strands of rats in two groups at each time, respectively. (, #). Yellow arrows indicated acellular strands, and red arrows indicated new vessel buds. Scale bar: 25 μm. Abbreviations: d: day; w: week; E/P: endotheliocytes to pericytes; ASs: acellular strands.
