Probe preparation:	Antisense labelled with S35 RNA
Visualized with:	Autoradiography

Structure	Level	Pattern	Image	Note
TS15: future brain	Present	Widespread	1A/B	Widespread expression was detected in the neuroepithelium.
TS15: neural tube	Present	Widespread	1A/B	Widespread expression was detected in the neuroepithelium.

Structure	Level	Pattern	Image	Note
TS20: forebrain	Present	Non-Uniform	2A/B	Expression was detected in the forebrain. The signal intensity over the ventral diencephalon is much lower than it is in other regions.
TS20: diencephalon	Present	Non-Uniform	2A/B	Weak expression was noted in the ventral diencephalon, while other regions were more strongly labeled.
TS20: hypothalamus	Weak		2A/B
TS20: nasal epithelium	Present	Regionally restricted	2A/B	Expression was detected in the neurogenic sensory nasal epithelium, but not in the nonneurogenic respiratory nasal epithelium.
TS20: nasal cavity respiratory epithelium	Absent		2A/B

Structure	Level	Pattern	Image	Note
TS20: hindbrain	Strong		2C/D
TS20: spinal cord	Strong		2C/D

TS20: lung	Present
TS20: metanephros	Present

Structure	Level	Pattern	Image	Note
TS23: neocortex	Present	Non-Uniform	2E/F	The highest concentration of signal was detected over the septal and medial cortex. The more lateral cortex was not as strong a signal.
TS23: ganglionic eminence	Weak		2E/F
TS23: cerebral cortex intermediate zone	Present		2E/F
TS23: cerebral cortex ventricular layer	Present		2E/F

Structure	Level	Pattern	Image	Note
TS23: nasal epithelium	Strong		2G/H	Robust labeling was detected in the sensory nasal epithelium.

TS23: thymus primordium	Present
TS23: trachea epithelium	Present
TS23: collecting duct	Strong	Regionally restricted		Strong signal was detected in the large papillary ducts of the collecting duct system.
TS23: renal pelvis	Strong	Regionally restricted		Strong expression was detected in papilla and renal pelvis.
TS23: ureter	Strong
