“…However, RG in the telencephalon, hypothalamus and spinal cord of adult zebrafish function as neural stem cells in both adult and regenerative neurogenesis (Adolf et al, ; Gorsuch et al, ; Hui, Nag, and Ghosh, ; Johnson et al, ; Kishimoto et al, ; Kizil et al, 2012; Kroehne, Freudenreich, Hans, Kaslin, and Brand, ; Mokalled et al, ; Raymond et al, ). Moreover, in the cerebellum, NE, but not RG, operate as neural stem cells in both physiological and regenerative conditions (Bae et al, ; Kaslin, Kroehne, Ganz, Hans, & Brand, ). RG and NE have different capacities as neural stem cell in different regions of the CNS and it is not well known how the regenerative abilities of RG and NE as neural stem cells are regulated.…”
