(a) Muscle fibrosis in PVM in different groups. Masson trichrome staining was used to determine the total amount of collagen in the muscle tissue. Collagen was stained blue; myofibers were stained red (Masson staining, ×200, Scale bar on pictures is 50 μm). (b) Quantification of the proportion of fibrotic area to the total cross-sectional area.
