Mosaic Heterochrony in Neural Progenitors Sustains Accelerated Brain Growth and Neurogenesis in the Juvenile Killifish N. furzeri (Current Biology)

Coolen et al. unravel in a fast-growing killifish a striking mosaic heterochrony within the pallial germinal zone, where progenitors at different maturation stages cohabit: radial glia, which enter precociously in an adult-like Notch-dependent quiescence and non-glial progenitors, which resemble early embryonic progenitors and ensure neurogenesis.
