text: Faithful progression through the cell cycle is crucial to the maintenance
and developmental potential of stem cells. Here, we demonstrate that neural stem
cells (NSCs) and intermediate neural progenitor cells (NPCs) employ a zinc-finger
transcription factor specificity protein 2 (Sp2) as a cell cycle regulator in
two temporally and spatially distinct progenitor domains. Differential conditional
deletion of Sp2 in early embryonic cerebral cortical progenitors, and perinatal
olfactory bulb progenitors disrupted transitions through G1, G2 and M phases,
whereas DNA synthesis appeared intact. Cell-autonomous function of Sp2 was identified
by deletion of Sp2 using mosaic analysis with double markers, which clearly established
that conditional Sp2-null NSCs and NPCs are M phase arrested in vivo. Importantly,
conditional deletion of Sp2 led to a decline in the generation of NPCs and neurons
in the developing and postnatal brains. Our findings implicate Sp2-dependent mechanisms
as novel regulators of cell cycle progression, the absence of which disrupts neurogenesis
in the embryonic and postnatal brain.
