Intravital Imaging Reveals Ghost Fibers as Architectural Units Guiding Myogenic Progenitors during Regeneration

Bhaskar Chanda Stem Cell Webster et al. show that the basal lamina remnants of degenerated skeletal muscle fibers, “ghost fibers,” are architectural units containing and guiding muscle progenitors during injury-induced regeneration in live mice. Their work identifies ghost fibers as the cellular mechanism regulating organization and number of regenerated fibers for proportional regeneration.
