Viral-mediated Labeling and Transplantation of Medial Ganglionic Eminence (MGE) Cells for In Vivo Studies

GABAergic cortical interneuron progenitors disperse, develop and synaptically integrate into a host cortex after transplantation. These cells can be easily transduced before transplantation for in vivo studies of genetically modified GABAergic precursors. Here, we show viral labeling techniques to target specific interneuron subgroups using existing Cre lines and Cre-dependent reporters.
