Ion Channel Activities in Neural Stem Cells of the Neuroepithelium

Figure 1

Schematic drawings of retinal neuroepithelial cells in cell cycle and the first differentiated neuron, a retinal ganglion cell. In chick embryo, the retina is composed almost homogeneously of neuroepithelial cells on embryonic day 3 (E3). The retinal ganglion cells are born mainly at E4–6. S: S-phase; M: M-phase. The outer (apical) surface faces the space that is continuous with the ventricle. This figure is cited from [5].
