Radial glial cell the onset of gliogenesis, it is unclear whether they are involved in spinal cord neurogenesis or migration. Radial glia have also been implicated in forming boundaries between different axonal tracts and white matter areas of the brain. As radial glia serve as the primary neural and glial progenitors in the brain, as well as being crucial for proper neuronal migration, defects in radial glial function can have profound effects in the development of the nervous system. Mutations in either Lis1 or Nde1, essential proteins for radial glial differentiation and stabilization, cause the associated neurodevelopmental diseases Lissencephaly and micro-lissencephaly (which literally
Glial scar animal). Further, a reduction in astrocytes and microglia, as well as a reduction in inflammation and angiogenesis, were observed. Interleukin-6 (IL-6) is thought to be a molecular mediator of glial scar formation. It has been shown to promote differentiation of neural stem cells into astrocytes. A monoclonal antibody, MR16-1, has been used to target and block the IL-6 receptors in rat spinal cord injury models. In a study by Okada "et al.", mice were intraperitoneally injected with a single dose of MR16-1 immediately after generating a spinal cord injury. Blockade of IL-6 receptors decreased the number of astrocytes present at
