Figure 8. Increased microvascular density in the PP-treated infarcted heart in a mouse model of myocardial infarction.

A. CD31⁺ capillaries in both border and infarcted zones in the scarred heart. The capillaries were identified with anti-CD31 antibodies in the cardiac sections prepared from the mice administered with vehicle (DMSO) (-PP) or PP (+PP). Scale bars: 50 μm. B. Quantitation of CD31⁺ capillary density. The data were collected from mice administered with vehicle (DMSO) (-PP) (n=3 mice) and with PP (+PP) (n=4 mice). CD31⁺ capillary density was measured as represented as capillary number/mm². Data: average±s.d. ^★p<0.05. NS: not significant.
