Probe:	Cxcr7 probe2
Probe preparation:	Antisense labelled with digoxigenin RNA

Structure	Level	Pattern	Image	Note
TS20: telencephalon	Present	Regionally restricted	1A	Expression was detected in the ventral telencephalon in the proliferative zones. Dorsal telencephalon was mainly devoid of staining.
TS20: medial ganglionic eminence	Present	Regionally restricted	1A	Expression was detected in the ventricular zone and subventricular zone.
TS20: lateral ganglionic eminence	Present	Regionally restricted	1A	Expression was detected in the ventral part.
TS20: cortical hem	Present	Regionally restricted	1A	Expression was detected in a small number of cells.

Structure	Level	Pattern	Image	Note
TS20: telencephalon	Present	Regionally restricted	1B	Expression in the subpallium formed two continuums. One was located between the ganglionic eminence and the ventral pial surface; these cells are likely to be olfactory tubercle neuron precursors migrating from the lateral ganglionic eminence. The second continuum of stained cells was positioned between the medial ganglionic eminence and the ventral cortex, suggestive of cortical interneurons generated in the medial ganglionic eminence and migrating towards the cortex.
TS20: cerebral cortex	Present	Regionally restricted	1B' , 1B	Expression was detected in a superficial layer of cells.

Structure	Level	Pattern	Image	Note
TS21: medial ganglionic eminence	Strong	Regionally restricted	1C	Expression was detected in the germinal zone.
TS21: cerebral cortex	Present	Regionally restricted	1C	Expression was detected in dorsomedial cortex.
TS21: cerebral cortex marginal layer	Present	Regionally restricted	1C	Expression was detected in the lateral cortex.
TS21: cerebral cortex subventricular zone	Present	Regionally restricted	1C	Expression was detected in the lateral cortex.

Structure	Level	Pattern	Image	Note
TS27: corpus striatum	Present	Regionally restricted	1E , 1E'	Expression was detected in the striatal subventricular zone.
TS27: cortical plate	Present	Regionally restricted	1E	Expression was concentrated in a deep and a superficial layer of the cortical plate.
