Sox10- Venus+ cells actively accumulate at the spinal cord injury site. Venus fluorescence illuminated the behavior of Sox10- expressing cells after a spinal cord injury. (A) In an intact adult mouse spinal cord, Venus+ cells were clearly visible in both in the gray and the white matter. (B) In the acute phase of contusive spinal cord injury (4 dpi; days-post-injury), Venus+ cells were absent from the lesion site. (C) In the subacute phase (14 dpi), numerous Venus+ cells were present around the lesion and delineated the lesion epicenter. Scale bars (A-C) 500 μm.
