Ghosts are not your typical cell biology research subjects but scientists at the Carnegie Institution for Science and the National Institute of Child Health and Human Development (NICHD) who developed a technique to observe muscle stem/progenitor cells migrating within injury sites in live mice, report that "ghost fibers," remnants of the old extracellular matrix left by dying muscle fibers, guide the cells into position for healing to begin.
