Axonal elongation into peripheral nervous system" bridges" after central nervous system injury in adult rats

S David, AJ Aguayo - Science, 1981 - science.org
The origin, termination, and length of axonal growth after focal central nervous system injury
was examined in adult rats by means of a new experimental model. When peripheral nerve …

Repertoire of microglial and macrophage responses after spinal cord injury

S David, A Kroner - Nature Reviews Neuroscience, 2011 - nature.com
Macrophages from the peripheral circulation and those derived from resident microglia are
