Extended Data Fig. 7: Dorsally-born GABAergic neuron signature across the developing cortical wall in late second trimester.

Immunostaining for DLX2, SCGN, and PAX6 shown in a GW17 (a) and GW24 (b) sample, tiling from the ventricular zone (bottom) to the cortical plate (top). Dotted white lines demarcate the bottom and top of tissue, as well as the SP/CP boundary, all identified with DAPI. Insets marked by white squares in the upper layers of the developing cortex correspond to immunostaining shown in Fig. 2i.
