Last part of PhD is online now! All credit goes to #DAVY lab members and collaborators :)
Questions arising:
1. How a developing organ sets up metabolism-dependent growth pattern?
2. If developmental time and trajectories are plastic, who counts the neuronal numbers (expected) during neurogenesis?

Very interesting stuff: sex differences intersect with region-specific transcriptional programs to regulate #astrocyte function www.cell.com/cell-reports...
Sex-specific astrocyte regulation of spinal motor circuits by Nkx6.1
Astrocytes play essential roles in functioning neuronal circuits and are regulated by regional transcription factors (TFs). Bosquez-Huerta et al. found that the TF Nkx6.1 is specifically expressed in astrocytes of the ventral spinal cord and that its deletion results in sex-specific effects on astrocyte morphology and spinal motor circuits.
