Comparative analysis of MI-induced changes in αSMA and collagen I expression in cardiac Sca1⁺CD31⁻ stromal cell populations of WT and A_2BKO ventricles. Representative cytofluorographic dot plots (a) of intracellular αSMA and collagen I (Col1) expression in cardiac Sca1⁺CD31⁻ stromal cell populations obtained from ventricles of WT and A_2BKO hearts before (d0) and on days 7 (d7) and 14 (d14) after MI. The numbers of αSMA⁺Col1⁺ (b), αSMA⁺Col1⁻ (c), αSMA⁻Col1⁻ (d), and Col1⁺αSMA⁻ (e) cells per milligram of tissue are presented as means ± SEM of 4 animals in each group. Asterisks indicate statistical differences (*p < 0.05, **p < 0.01) between corresponding WT and A_2BKO values analyzed by one-way ANOVA with Bonferroni post-hoc tests
