TS28: cortical layer V	neuron	Present		1D DKO Satb2/Ctip2	The localization of the immunopositive neurons of the double knockout was more similar to wild type at P7.
TS28: cortical layer VI	neuron	Present		1D DKO Satb2/Ctip2	Some immunopositive cells were still observed in the lowest layers (bins 1-4, Layer VI) in the double knockout.
