Capillary density is increased acutely after MI in the remote zone of E2f1 deficient hearts. mRNA expression of Pdgfb (a). Representative images of isolectin-stained hearts (b). Capillary density in border zone (“BZ”, panel c), infarct zone (“IZ”; panel d), and remote zone (“RZ”; panel e). Bcl2 mRNA expression (f). Representative TUNEL-stained sections (g). Quantification of TUNEL positive cells (h). Representative images for cardiac fibrosis (i) and quantification (j). An unpaired Student’s t test was used to determine significance between E2f1^+/+ and E2f1^−/− groups
