Probe:	Stoml3 cDNA2
Probe preparation:	Antisense labelled with digoxigenin RNA
Visualized with:	Alkaline phosphatase

Structure	Level	Pattern	Image	Note
TS27: olfactory epithelium	Present		3A
TS27: nasal cavity respiratory epithelium	Absent		3A
TS27: vomeronasal organ	Absent		3A

Structure	Level	Pattern	Image	Note
TS28: olfactory epithelium	Present	Regionally restricted	3B	Expression was detected in the olfactory receptor neurons situated in several layers in the middle region of the neuroepithelium. Staining was absent from sustentacular and microvillar cells and globose and horizontal basal cells.
TS28: olfactory gland	Absent		3B	No signal was seen in Bowman's gland acinar cells.

Structure	Level	Pattern	Image	Note
TS23: olfactory epithelium	Absent		5_SLP3

Structure	Level	Pattern	Image	Note
TS25: olfactory epithelium	Present	Non-Uniform	6A	Expression was detected surrounding the nuclei of the most apical sensory neurons.

Structure	Level	Pattern	Image	Note
TS27: olfactory epithelium	Present	Regionally restricted	6C	Expression was detected in olfactory neurons located in central regions of the epithelium. The number of expressing cells increased substantially compared to E17.5.
