Values are mean ± SEM. Differences were tested by using 1-way analysis of variance, followed by post hoc Tukey-Kramer test. ∗p < 0.05 and ∗∗p < 0.01 vs. CTRL. †p < 0.05 and ‡p < 0.01 vs. SS. Representative photomicrographs of <b>(A)</b> Masson trichrome staining (MT), <b>(B)</b> immunostained CD34-positive cells, and <b>(C)</b> terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL)-positive cells are shown (n = 4 in each group). Arrowhead in <b>(C)</b> indicates TUNEL-positive cell. Other abbreviations as in Figure 2.
