  • What is the role of pericytes in the brain?

    We do not know, they are like astrocytes.
  • What are the astrocytes subtypes?

    • fibrous
    • protoplastic
  • Where do fibrous astrocytes reside?

    In the white matter and express GFAP.
  • Which astrocytes are characterized by GFAP?

    fibrous astrocytes
  • What is the role OPCs in synapses?

    They help neurons to form synapses.
  • What is the function of NG2 cells?

    They can become protoplasmic astrocytes, then oligodendrocytes. So it is a sort of replenisher.
  • What is yet unknown in relation to oligodendrocyte markers?

    The factors are not super subtype specific because they are mostly related to myelination.
  • Where do glia originate?

    neuroepithelial cells that line the cerebral ventricles and spinal canal, they make embryonic radial glia, which gives rise to astrocytes and oligodendrocytes.

    • neuroepithelial cells
    • radial glial
    • intermediate progenitors
    • adult cells
  • Where do neural progenitors reside?

    Near the ventricles.
  • Explain neural tube diversity

    SHH, BMP and other factors create unique environment that induces unique gene expression.
