Overview

• Zebrafish can fully regenerate their spinal cords by altering the functions of injured neurons.
• The survival and adaptability of neurons are more critical than stem cells in the regeneration process.
• New research maps the detailed cellular changes in zebrafish post-injury, identifying potential genetic targets for therapy.
• Human spinal cord injuries often lead to neuron death, hindering regenerative efforts.
• Future studies will explore the role of other cell types in spinal cord regeneration and compare findings with mammalian cells.
