How to Find the Correct Markers to Label Neuroepithelial Cells

Below is a guide on how to choose the appropriate markers to label neuroepithelial cells.

The neural plate and the neural tube, during embryonic development, are formed by neuroepithelial (NE) cells that are divided symmetrically. They have particular features of the epithelium, such as tight junctions, and are highly polarized along their apical-basal axis.

Nestin

Nestin is a protein that appears in NE cells and it is an intermediate filament. Its expression in the cells continues in radial glia until astrocyte development.

SOX2

SOX2 is related to the neural plate as it is its earliest transcription factor. It is expressed in proliferating cells and those that acquire glial fates, but is downregulated in post-mitotic neurons.

Notch1

The formation, migration, and differentiation of neural crest cells are regulated by the Notch1 transmembrane receptor.

HES1 and HES3

The symmetrical cell division of the NE cells is sustained with the HES1 and HES3 transcription factors. When NE cells become radial glia, HES3 is downregulated and HES5 is upregulated.

Occludin

Occludin is lost after neural tube closure prior to neurogenesis. It is a tight junction protein.

E-Cadherin

A cell adhesion molecule downregulated after neural tube closure prior to neurogenesis.

SOX10

The SOX10 transcription factor appears in migrating neural crest cells.
