Figure 3. Fibrosis is increased in Mb hearts 13 weeks after TAC.

Figure 3

(A) Representative sirius red staining for fibrosis in FVB and Mb hearts. (B) Semiquantitative scores for fibrosis staining performed as described in Methods by a blind observer. Staining of fibrosis in Mb-TAC hearts was significantly higher than that in FVB-TAC hearts. The expression of collagen 1 mRNA (panel C) measured by quantitative RT-PCR was significantly higher in Mb-TAC hearts than in FVB-TAC hearts. Expression of collagen 3 mRNA (panel D) was elevated in TAC hearts but not significantly different in Mb-TAC versus FVB-TAC hearts. #P<0.05, Mb-TAC vs. FVB-TAC and *P<0.05, Sham vs. TAC by 2-way ANOVA, n = 5 for each group.
