Prospective isolation of cortical interneuron precursors from mouse embryonic stem cells.

Despite their therapeutic potential, progress in generating fully differentiated forebrain neurons from embryonic stem cells (ESCs) has lagged behind that from more caudal regions of the neuraxis. GABAergic interneuron precursors have the remarkable ability to migrate extensively and survive after transplantation into postnatal cortex, making them an attractive candidate for use in cell-based therapy for seizures or other neuropsychiatric disorders. We have modified a mouse ESC line with an Lhx6-GFP reporter construct that allows for the isolation of newly generated cortical interneuron precursors.
