Bulk and mosaic deletions of Egfr reveal regionally defined gliogenesis in the developing mouse forebrain

ISCIENCE, 26(3).

By: X. Zhang n, G. Xiao n, C. Johnson n, Y. Cai n, Z. Horowitz n, C. Mennicke n, R. Coffey*, M. Haider* ...

TL;DR: Subtractive bulk ventral and dorsal forebrain deletions of Egfr uncovered significant and permanent decreases in oligodendrogenesis and myelination in the cortex and corpus callosum, and a regenerative population of gliogenic progenitors in the mouse forebrain may compensate for the missing EGFR-dependent dorsal glia in the bulk Egfr-deleted forebrain.
