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

Figure 3 Representative images of immunostaining for pSmad2/3 and Smad7 in the groups over time. Target protein positive staining is yellow or brownish-yellow. Original magnification 100×. Histogram shows integral optical densities of target proteins. ^bP < 0.01 vs group A; ^dP < 0.01 vs group B; ^fP < 0.01 vs group C; ^hP < 0.01 vs week 9. IOD: Integral optical density.
