Probe:	Pax2 cDNA3
Probe preparation:	Antisense RNA

Structure	Level	Pattern	Image	Note
TS19: retina	Present	Regionally restricted	3E	At this stage, transcripts are restricted to the converging lips of the retina on both sides of the optic fissure.

Structure	Level	Pattern	Image	Note
TS20: optic stalk	Present	Regionally restricted	4B	Only in the optic stalk region, continuous to the pigmented epithelium of the optic cup, the expression extends to dorsal regions of the stalk. The limit is sharply defined such that no cell expressing Pax2 shows pigmentation.
TS20: optic fissure	Present	Regionally restricted	4B	Ventral expression at the optic fissure extends from the distal regions to the basis of the diencephalon.
TS20: diencephalon	Absent		4B
TS20: pigmented retinal epithelium	Absent		4B

Structure	Level	Pattern	Image	Note
TS15: optic stalk	Present		6C
TS15: diencephalon	Absent		6C

Structure	Level	Pattern	Image	Note
TS19: diencephalon	Present	Regionally restricted	6H	Pax2 expression has extended medially into the gap left by Shh, so that the expression pattern is now continuous ventrally, yet still not overlapping the Shh expression domain.
TS19: optic recess	Present	Regionally restricted	6H	Pax2 expression has extended medially into the gap left by Shh, so that the expression pattern is now continuous ventrally, yet still not overlapping the Shh expression domain.
