Two main types of astrocytes are found in the SGZ: radial astrocytes and horizontal astrocytes. Radial astrocytes are synonymous with the radial glia cells described earlier and play dual roles as both glial cells and neural stem cells. It is not clear whether individual radial astrocytes can play both roles or only certain radial astrocytes can give rise to NSCs.
Two primary types of astrocytes are present in the SGZ: radial astrocytes and horizontal astrocytes. Radial astrocytes are equivalent to the radial glia cells previously described and fulfill dual functions as both glial cells and neural stem cells. The distinction between individual radial astrocytes' capabilities remains unclear, whether they can perform both roles or only certain ones give rise to NSCs.
