The protein encoded by ctgfa ( connective tissue growth factor a ) is secreted after injury and encourages glial cells to form a bridge across the spinal lesion. Loss of Fgf function inhibits formation of this “glial bridge” and prevents axon regeneration. Adult zebrafish are capable of regenerating axonal tracts and can restore full functionality after SCI. 2020 Jul 5;21(13):4768. doi: 10.3390/ijms21134768.

We are a neural regeneration laboratory in the Department of Developmental Biology at Washington University School of Medicine in St. Louis, USA. Zebrafish glia are induced by Fgf signaling, to form an elongated bipolar morphology that forms a bridge between the two sides of the resected spinal cord, over which regenerating axons actively migrate. 2020 Jul 5;21(13):4768. doi: 10.3390/ijms21134768. In contrast, the zebrafish glia form a bridge that spans the injury site but allow the penetration of axons into it.

However, a small, tropical freshwater fish native to South East Asia called zebrafish has the ability to rapidly regenerate their nervous tissue. Wnt signaling controls pro-regenerative Collagen XII in functional spinal cord regeneration in zebrafish. As a consequence of an injury there is very little repair of disengaged axons and therefore functional deficit persists after SCI in adult mammals.

MicroRNA miR-133b is essential for functional recovery after spinal cord injury in adult zebrafish. In contrast, peripheral nervous system axons readily regenerate following injury and hence allow functional recovery both in mammals and fish. A freshwater zebrafish costs less than two bucks at the pet store, but it can do something priceless: Its spinal cord can heal completely after being severed, a paralyzing and often fatal injury for humans. 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).
