In contrast to mammals, zebrafish can efficiently regenerate and recover lost tissue architecture and the function of vital organs including the spinal cord, retina, fin, heart and brain (Figure 1). The scarcity of oligodendrocytes in the lesion site impairs remyelination of spared fibres, which leaves axons denuded, impedes signal transduction and contributes to permanent functional deficits.

The scarcity of oligodendrocytes in the lesion site impairs re-myelination of spared fibres, which leaves axons denuded, impedes signal transduction and contributes to permanent functional deficits. This is a major barrier in mammalian spinal cord regeneration,” Prof Currie said. Glial cell ecology in zebrafish development and regeneration. USA.gov. Spinal cord regeneration in zebrafish is complex, involving inflammation, cell death, cell migration, cell proliferation, neurogenesis, axonogenesis, and tissue- and circuit-level remodeling (Hui et al., 2014). The extent of axonal regeneration has been evaluated by using various injury paradigms, such as transection or crush injury in zebrafish spinal cord (Becker, Reactive oligodendrocyte progenitor cells (re-)myelinate the regenerating zebrafish spinal cord. Here we demonstrate that adult zebrafish, which show functional spinal cord regeneration, are capable of motor neuron regeneration. Wehner D, Tsarouchas TM, Michael A, Haase C, Weidinger G, Reimer MM, Becker T, Becker CG. Remarkably, the function of Notch in the regenerating spinal cord of zebrafish is similar to its proposed role in the lesioned spinal cord of rats, where Notch is strongly upregulated and acts as an anti-neurogenic factor in vitro (Yamamoto et al., 2001). Thus, our data illustrate a conserved role for Wnt/β-catenin signaling in adult and larval zebrafish spinal cord regeneration. USA.gov. We performed gene expression analysis using microarray to find damage-induced genes after spinal cord injury, and found that Sox11b mRNA is up-regulated at 11 days after injury.
