Effect of activin inhibition to fibrotic alterations in experimental fibrosis. The histological fibrotic alterations related to asbestos (Asb) and silica exposure, and the effect of sActRIIB-Fc to these alterations in mice (A). The photomicrographs (B) show representative haematoxylin-eosin-stained sections from the treated and non-treated groups in both the asbestos- and silica-exposed groups. P values from Kruskal-Wallis (comparing three groups) and Mann-Whitney U test (comparing two groups) are indicated in A.
