Scientists identify cells for spinal-cord repair

Coronal sections of injured adult spinal cord, anterior to posterior. The labelling shows recombined ependymal cells and their progeny (white) migrating out to the injury area in the dorsal funiculus, as a reponse to the injury (injury is in the image on the right hand corner). The mouse is a FoxJ1-CreER x R26R-LacZ reporter. Image / Konstantinos Meletis
