muscle

abnormal muscle morphology ( J:150030 )

• mice exhibit improved muscle and sarcolemmal structure, more uniform fiber diameter, reduced inflammatory cell between adjacent fibers, and decreased necrosis and fibrosis compared with Dmd^mdx homozygotes

enhanced skeletal muscle regeneration ( J:150030 )

• myofiber regeneration is increased compared to in Dmd^mdx homozygotes

immune system

decreased macrophage cell number ( J:150030 )

• fewer macrophages accumulate in the muscles compared to in Dmd^mdx homozygotes

hematopoietic system

decreased macrophage cell number ( J:150030 )

• fewer macrophages accumulate in the muscles compared to in Dmd^mdx homozygotes
