Extended Data Fig. 1: Aberrant vascularization characterizes infarcted cardiac tissue.
Mice were subjected to MI surgery or sham operation. Hearts were excised 3 weeks after surgery. Tissue sections were immunostained with (a) anti-CD31 antibody, (b) anti-NG2 and anti-CD31 antibodies, or (c) anti-collagen IV and anti-CD31 antibodies. a, Representative images in normal tissue and infarct zone are shown (n = 3 mice). Bars indicate 100 µm. b,c, Left, representative images in normal tissue and infarct zone are shown. Right, quantified results (mean ± SEM, n = 3 mice). Statistical analysis by unpaired two-tailed Students’ t test. Bars indicate 100 µm.
