The science behind the zebra fish’s ability to repair its spinal cord after injury has been unlocked by new research.
In humans, glia cells are responsible for preventing bleeding of the spinal cord. In doing this, the glia creates a “scar”. This scar creates a barrier which prevents healing, and paralysis results. In the zebra fish, the same process takes place, but the scar can be penetrated to allow healing.
Scientists hope that the research will lead to treatments for paraplegics and quadriplegics.Read more at Monash University
