Extended Data Fig. 13: Deep and upper layer neurogenesis throughout second trimester.

(a) Full cortical thickness of pre-midgestation samples co-stained with PAX6, TBR1 and SATB2 from VZ (bottom) to CP (top). GW16, GW18, and GW24 samples correspond to images in Fig. 4. (b) Full cortical thickness of post midgestation samples co-stained with PAX6, TBR1 and SATB2 from VZ (bottom) to CP (top). GW24 sample corresponds to images in Fig. 4. (c) Insets of the VZ and ISVZ showing TBR1 and SATB2 from full thickness images for samples in (b). In all panels, the ventricular surface is labeled with a white dotted line.
