Spinal cord repair in regeneration-competent vertebrates: Adult teleost fish as a model system

► We review the excellent regenerative capacity of the spinal cord in adult teleost fish. ► We compare this capacity between the different classes of regeneration-competent vertebrates. ► We cover morphological, cellular, molecular, and functional aspects of spinal cord regeneration. ► We discuss the relevance of these findings for overcoming the limits of spinal cord repair in mammals.
