 Mechanical brain injury also induces cell migration and proliferation, as was observed in rodents, and it may also increase cell number, negating the previously held notion that no new neuronal cells can be generated.In conclusion, this group was able to determine that cells in the SVZ are able to produce new neurons and glia throughout life, given it does not suffer damage as it is sensitive to any deleterious effects.Therefore, the SVZ can recover itself following mild injury, and potentially provide for replacement cell therapy to other affected regions of the brain.
