Figure 3 (A) Representative immunoblots showing transforming growth factor (TGF)-ß1 protein level in the infarcted and non-infarcted sites on days 3 and 14 among sham-operated rats (Sham), Sham treated with romurtide (Sham/Ro), myocardial infarction rats treated with saline (MI/C), and MI treated with romurtide (MI/Ro). (B) Quantified data of TGF-ß1 protein expression in the infarcted and non-infarcted sites among Sham, Sham/Ro, MI/C, and MI/Ro (n = 4 per group). Values are mean ± SEM. *p < 0.05 versus Sham; p < 0.05 versus Sham/Ro; p < 0.05 versus MI/C.
