Radial glia cells give rise to which types of progenitors?

• A. Oligodendrocyte progenitors
• B. Astrocyte progenitors
• C. Neuronal and glial cell progenitors
• D. Ependymal progenitors

Answer: (C)

Radial glia are multipotent neural progenitors in development. They don’t commit to a single cell type right away—they first generate neuronal progenitors, which become neurons, and then switch to gliogenesis, producing glial progenitors that give rise to glial cells such as astrocytes and oligodendrocytes. So, their overall progenitor output includes both neuronal and glial lineages, making “neuronal and glial cell progenitors” the best fit. The other options point to one specific glial fate or another lineage, which doesn’t capture the full range of radial glia’s developmental potential.
