Abstract
In contrast to mammals, fish and amphibia functionally regenerate axons in the central nervous system (CNS). The strengths of the zebrafish model, that is, transgenics and mutant availability, ease of gene expression analysis and manipulation and optical transparency of larvae lend themselves to the analysis of successful axonal regeneration. Analyses in larval and adult zebrafish suggest a high intrinsic capacity for axon regrowth, yet signaling pathways employed in axonal growth and pathfinding are similar to those in mammals. However, the lesioned CNS environment in zebrafish shows remarkably little scarring or expression of inhibitory molecules and regenerating axons use molecular cues in the environment to successfully navigate to their targets. Future zebrafish research, including screening techniques, will complete our picture of the mechanisms behind successful CNS axon regeneration in this vertebrate model organism.
