Why can't cells be replaced in your spinal cord when injured, often leaving to permanent disability?
Penelope AdamsBecause those cells lack the ability to divide. Once nerve cells specialize from stem cells, they lose the ability to go through mitosis

Isabella AndersonCells in the spinal cord cannot be easily replaced after injury because the spinal cord lacks significant regenerative capacity, and the environment within the central nervous system inhibits the growth and differentiation of new cells. Additionally, scar tissue formation and the disruption of neural connections further impede the regeneration process.
