Exogenous bone morphogenetic protein-7 reduces hepatic fibrosis in Schistosoma japonicum-infected mice via transforming growth factor-β/Smad signaling

Figure 2 Representative images of immunostaining for transforming growth factor-beta 1 and alpha-smooth muscle actin in the groups over time. Target protein positive staining is yellow, brownish-yellow or snuff. Original magnification 100×. Histogram shows integral optical densities of target proteins. TGF-β1: Transforming growth factor-beta 1; α-SMA: Alpha-smooth muscle actin; IOD: Integral optical density. ^bP < 0.01 vs group A; ^dP < 0.01 vs group B; ^fP < 0.01 vs group C; ^hP < 0.01 vs week 9.
