Regeneration of the central nervous system-principles from brain regeneration in adult zebrafish

Figure 2 Schematic representation of the main cell types in the adult zebrafish telencephalon, with focus on two distinct neurogenic niches, the dorsal ventricular zone and the medio-ventricular zone. A: The dorsal ventricular zone hosts ependymoglial cells (light green), quiescent and slow-cycling adult neural stem cells, intermediate progenitor cells (light blue) and neurons (yellow); B: The medio-ventricular zone hosts neuroepithelial-like cells (magenta), characterized by faster cell cycle. Intermediate progenitor cells (light blue) are deposited in the subventricular layer and they can either differentiate into neurons (yellow) or migrate to the olfactoy bulb. Microglial (blue) and oligodendroglial (brown) cells can be found in the subventricular zone and in the parenchyma of the adult zebrafish telencephalon.
