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

Figure 1 Representative images of schistosomal hepatic fibrosis in the groups over time. Collagen fibers are stained blue and arrows show egg granulomas. Original magnification 100×. Histogram shows the percentage of collagen which represented the degree of hepatic fibrosis. ^bP < 0.01 vs group A; ^dP < 0.01 vs group B; ^fP < 0.01 vs group C; ^hP < 0.01 vs week 9.
