WebFeb 9, 2024 · As neural stem cells are required for neurogenesis, it was concluded that this process can occur in mammalian brains. Significant advancements have been made since this discovery of neural stem cells in mammals, in almost every aspect of adult neurogenesis in the mammalian CNS. WebMany forms of brain and spinal cord (CNS) damage cut axons. Where axons can regenerate, as in peripheral nerves, they can bring back function. However in the CNS axon regeneration fails. This is the main reason why paralysis and loss of sensation is permanent in conditions such as spinal cord injury. Many laboratories are therefore […]
