Abnormal collagen synthesis in skeletal muscle of dystrophic chicken.
Specific molecular properties of skeletal muscle collagens from normal and dystrophic chickens have been compared. When dystrophy develops in skeletal muscle tissue there was an increase in the amount of total collagen and an increased proportion of Type III collagen in the tissue. The results from the cross-link study as well as the analysis of the solubility of collagen showed that skeletal muscle of dystrophic chicken produces more immature collagen fibers compared to normal chicken. These findings strongly indicate an important role of collagen in the pathogenesis of the extensive connective tissue prolipheration characteristic of muscular dystrophies.
