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

Figure 4

The enriched environment increased VEGF expression surrounding the contralateral cingulate. At 14 days after MCAO/r, VEGF surrounding the bilateral cingulate were measured and analysed by immunostaining.
