Structure	Level	Pattern	Image	Note
TS22: adenohypophysis	Strong		2A	Strong expression in anterior lobe of pituitary.
TS22: hindbrain	Present	Regionally restricted	2A	Expression in dorsal hindbrain and hindbrain flexure
TS22: nose	Present	Regionally restricted	2A	Expression in fronto-nasal mass.

Structure	Level	Pattern	Image	Note
TS22: adenohypophysis	Strong	Regionally restricted	2B	Expression restricted to ventro-posterior quadrant, expressed by most cells within this domain.
TS22: remnant of Rathke's pouch	Present		2B	Expression domain includes cells lining residual luman of Rathke's pouch.

Structure	Level	Pattern	Image	Note
TS22: adenohypophysis	Present	Regionally restricted	3A	Expression confined to ventro-posterior quadrant of pituitary. No expression in dorsal luminal lining cells.
TS22: neurohypophysis infundibulum	Weak		3A	Low levels expression in infundibulum.

Structure	Level	Pattern	Image	Note
TS17: future adenohypophysis	Weak	Regionally restricted	4A	Low levels of expression in infundibulum.
TS17: Rathke's pouch	Absent		4A

Structure	Level	Pattern	Image	Note
TS20: adenohypophysis	Present	Regionally restricted	4B	Authors report expression activated in presumptive anterior lobe.

Structure	Level	Pattern	Image	Note
TS22: adenohypophysis	Present	Regionally restricted	4C	Expression in undifferentiated cells of ventro-posterior domain.

Structure	Level	Pattern	Image	Note
TS24: adenohypophysis	Present	Regionally restricted	4D	Expression restricted to two patches of periluminal cells, which may correspond to residual progenitor cells.
