Correct Answer � C
Explanation

Answer is C. Microglial cells
Neuroepithelial cells are neuroectodermal in origin and are found in the ventricular zone of the neural tube. These are the ‘stem cells’ which differentiate further into neurons, astrocytes, and other glial cells.
Most glial cells are derived from ectodermal tissue (neural tube and crest). The exception is microglia, which are derived from hematopoietic stem cells (mesenchymal in origin).
