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

Overview

This study demonstrates a method for virally transducing GABAergic progenitor cells from the medial ganglionic eminence (MGE) before their transplantation into a host cortex. The approach allows for the study of genetically modified interneuron subgroups in a more natural environment.

Key Study Components

Area of Science
