FOXG1 drives transcriptomic networks to specify principal neuron subtypes during the development of the medial pallium


ABSTRACT: The medial pallium (MP) is the major forebrain region underlying learning and memory, spatial navigation, and emotion; however, the mechanisms underlying the specification of its principal neuron subtypes remain largely unexplored. Here, by postmitotic deletion of FOXG1 (a transcription factor linked to autism and FOXG1 syndrome) and single-cell RNA sequencing, we found that FOXG1 controls the specification of upper-layer retrosplenial cortical pyramidal neurons (RSC-PyNs (UL)), subiculum PyNs (SubC-PyNs), CA1-PyNs, CA3-PyNs and dentate gyrus granule cells (DG-GCs) in the mouse MP. We uncovered subtype-specific and subtype-shared FOXG1-regulated transcriptomic networks orchestrating MP neuron specification.
