Intramyocardial injection of CM after MI promotes neovascularization of the ischemic myocardium. Myocardial sections were immunostained to identify capillaries and arterioles. vWF⁺ vessels were counted (A). Proliferating vWF⁺ vessels were identified by co-expression of the proliferating cell nuclear antigen Ki67 (arrow heads) (B). Arterioles were immunostained with αSMA (C). Serial sections were double stained for αSMA and Ki67 (arrow heads) (D). Data are presented as mean ± S.E.M. N= 10–12/group. *P < 0.05.
