Probe preparation:	Antisense labelled with digoxigenin RNA
Visualized with:	Alkaline phosphatase

Structure	Level	Pattern	Image	Note
TS20: cortical antihem	Present		2B	Peak of expression overlapping with that of Tgfa in curving longitudinal band of cortical antihem

Structure	Level	Pattern	Image	Note
TS20: telencephalon	Present	Graded	3C	Expression peaks in Tgfa-expressing domain but dxtends as a decreasing gradient into dorsolateral cortical neuroepithelium, with an additional zone of expression in medial cortical primodrium.

Structure	Level	Pattern	Image	Note
TS20: cerebral cortex	Present		3H	Expression in cortical neuroepithelium.
TS20: telencephalon ventricular layer	Present	Regionally restricted	3H	Expression extends into ventricular zone of basal telencephalon.

Structure	Level	Pattern	Image	Note
TS22: cortical antihem	Present		4G	Dense expression at antihem region at E14.5

Structure	Level	Pattern	Image	Note
TS22: telencephalon	Present	Regionally restricted	4H	Expression missing from antihem region.
TS22: cerebral cortex ventricular layer	Trace	Regionally restricted	4H	Expression in lateral cortical ventricular zone almost undetectable.
TS22: hippocampus	Present		4H	Expression remains in hippocampal primordium.
