Extended Data Fig. 8: Dorsally-born GABAergic neuron signature increases during midgestation and persists into third trimester.

(a) Additional GW22 sample demonstrates morphology of SCGN + PAX6+ cells in the CP and MZ. (b-c) Additional examples of pre- (b) and post- (c) midgestation samples co-stained with SCGN and PAX6. Full cortical thickness is shown, from VZ (bottom) to CP (top). (d-e) Third trimester samples stained with SCGN and PAX6. Cortical plate and marginal zone are shown with a dotted line at the border. Yellow arrows indicate representative SCGN + PAX6+ cells.
