An Enriched Environment Enhances Angiogenesis Surrounding the Cingulum in Ischaemic Stroke Rats

Figure 7

The enriched environment increased eNOS generation surrounding the bilateral cingulate. The expression of eNOS in endothelial cells surrounding the bilateral cingulate was analysed by immunostaining at 14 days after MCAO/r. (a, b) Representative images of eNOS-positive endothelial cells surrounding the contralateral cingulate in MCAO/r rats in the standard cage (a) and enriched environment groups (b). (c) The area of eNOS-positive endothelial cells surrounding the contralateral cingulate in MCAO/r rats in the SC and EE groups was used for statistical analysis. rats per group, , . (d–f) eNOS-positive cells surrounding the ipsilateral cingulate in MCAO/r rats in the standard cage (d) and enriched environment groups (e) were also analysed (f). rats per group, , .
