TS26: lung alveolus	Absent		1F	Absent in the respiratory epithelium.

Structure	Level	Pattern	Image	Note
TS18: lung	Weak	Regionally restricted	2A	Expression is in the stroma.

Structure	Level	Pattern	Image	Note
TS18: lung	Present	Regionally restricted	2B	Expression accumulates around the epithelial ducts.

Structure	Level	Pattern	Image	Note
TS21: lung	Strong	Regionally restricted	2E	Expression is in the stroma and at branch points.

Structure	Level	Pattern	Image	Note
TS21: lung	Strong	Regionally restricted	2F	Expression is in the stroma and at branch points, and around ducts of high columnar epithelium.

Structure	Level	Pattern	Image	Note
TS23: lung	Present	Regionally restricted	3A	Expression is concentrated at the crotches of the epithelial branches and forms a sleeve around the bronchiolar ducts. Absent at the sruface of the terminal buds.
