Comparison of spinal cord regeneration capacity in zebrafish and medaka

Unlike mammals, zebrafish have the remarkable ability to regenerate many tissues, including the spinal cord. Medaka, another model fish species, has a low regenerative ability in the spinal cord. Therefore, comparisons with them advantageous to revealing regeneration-specific mechanisms in the spinal cord. The comparison of the spinal cord regeneration abilities of zebrafish and medaka could be a promising research field to elucidate new factors that determine spinal cord regeneration ability.
