Data on the recovery of glycinergic neurons afterspinal cord injury in lampreys

Abstract

We used immunohistochemical methods to quantify changes inthe number of glycine-immunoreactive neurons of the dorsome-dial, lateral and cerebrospinalfluid contacting cell populations ofthe spinal cord of larval sea lampreys after a complete spinal cordinjury. The data presented here are quantifications of the numberof glycine-immunoreactive neurons located in the rostral andcaudal stumps of the spinal cord and the corresponding statisticalanalyses. These data show that, glycine immunoreactivity is lost inglycinergic neurons immediately after injury and that the numberof glycine-immunoreactive neurons is recovered in the followingtwo weeks. These data are useful for researchers investigatingdeterminants that underlie the spontaneous recovery of locomo-tion following spinal injuries in regenerating animal models, andfor analysing the role of glycinergic neurons in spinal cord repairafter an injury
