Foxp1 suppresses cortical angiogenesis and attenuates HIF-1alpha signaling to promote neural progenitor cell maintenance.

Neural progenitor cells within the cerebral cortex undergo a characteristic switch between symmetric self-renewing cell divisions early in development and asymmetric neurogenic divisions later. Yet, the mechanisms controlling this transition remain unclear. Previous work has shown that early but not late neural progenitor cells (NPCs) endogenously express the autism-linked transcription factor Foxp1, and both loss and gain of Foxp1 function can alter NPC activity and fate choices.

Wiring the Human Brain: A User's Handbook.

Brain function requires connecting neuronal networks to empower movement, sensation, behavior, and cognition. Studies published early this year provide evidence that in humans, Netrin receptor, Deleted in Colorectal Cancer (DCC), is a master regulator of axonal crossing throughout the neuraxis.
