Zebrafish Reveal Promising Mechanism for Healing Spinal Cord Injury

Preliminary results in mice show that Fgf injections near a spinal injury increase both the number of glia cells at the site and the elongated morphology. Their evidence suggests that Fgfs may work to create an environment more supportive of regeneration in mammals as well and could be a valuable therapeutic target.

Myelination, Schwann Cells Devastated in Erk Knock-out Mice

The researchers knocked out the Erk gene during peripheral nervous system development in mice. The researchers noticed the neurons of these knock-out mice were largely unaffected, but Schwann cells were "just devastated at every stage of development."
