From: Physical rehabilitation improves muscle function following volumetric muscle loss injury
Physical rehabilitation in the form of voluntary wheel running prevents collapsing of muscle fibers. The muscle fibers collapse around the injury site in the SED group (A), while they enclose the fibrotic scar in the RUN group (B). In either group, the area immediately adjacent to defect has disorganized muscle fibers. Scale bar = 100 μm.
