Visualized with:	Alkaline phosphatase

Structure	Level	Pattern	Image	Note
TS21: lateral ganglionic eminence ventricular zone	Strong	Regionally restricted	2C	High level expression in progenitor ventricular region 1 and 2 (pLGE1-2). Expression in the rest ventricular region (pLGE3-4) was in a lower level.
TS21: medial ganglionic eminence ventricular zone	Present		2C	Expressed in the progenitor ventricular regions, with scattered expression in the most dorsal domain (pMGE1).
TS21: telencephalon	Present	Regionally restricted	2C	Expressed in the septum.

TS21: lateral ganglionic eminence ventricular zone	Present		3C	Expressed in the progenitor ventricular regions.
TS21: medial ganglionic eminence ventricular zone	Present		3C	Expressed in the progenitor ventricular regions.
TS21: preoptic area	Absent		3C

Structure	Level	Pattern	Image	Note
TS21: lateral ganglionic eminence	Present		4B	Expression was stronger in the most dorsal parts of the basal ganglia (pLGE1 and pLGE2).
TS21: medial ganglionic eminence	Present		4B
TS21: prethalamus	Present		4B
TS21: hypothalamus	Present	Regionally restricted	4B	Expressed in the progenitor domain from the hypothalamic preoptic area.

TS21: lateral ganglionic eminence	Present		6C
TS21: medial ganglionic eminence	Present		6C
TS21: telencephalon	Present		6C	Expressed in most parts of the septum but is absent from the most ventromedial part.
