Figure 4.
TUNEL staining in infarcted (1 day post-MI) WT and MyD88−/− hearts. (A) Green fluorescence shows TUNEL positive nuclei whereas blue fluorescence represents total stained nuclei with DAPI. Scale bars= 50 µm. (B) Post-MI MyD88−/− hearts had significantly less TUNEL positive nuclei (3 hearts each group, *P ≤ 0.01).
