Note: Conditional mutant.
Structure Level Pattern Image Note
TS21: salivary gland Absent 3A No staining is observed, indicating no Ascl1-driven cre expression at the early bud or pseudoglandular stage.

Specimen Fig. 3B: embryonic day 15.5; Ascl3tm1(EGFP/cre)Ovi/Ascl3+, Gt(ROSA)26Sortm1Sor/Gt(ROSA)26Sor+ (more )
Note: Conditional mutant.
Structure Level Pattern Image Note
TS23: salivary gland Present Regionally restricted 3B Staining is observed in cells in the large excretory duct in the salivary gland at the canalicular stage.

Specimen Fig. 3C: embryonic day 17.5; Ascl3tm1(EGFP/cre)Ovi/Ascl3+, Gt(ROSA)26Sortm1Sor/Gt(ROSA)26Sor+ (more )
Note: Conditional mutant.
Structure Level Pattern Image Note
TS25: salivary gland Present Regionally restricted 3C Staining is observed in cells in ductal structures at the terminal bud stage. No staining is observed in the terminal end buds (presumptive acinar cells.)

Specimen not shown: embryonic day 17.5; Ascl3tm1(EGFP/cre)Ovi/Ascl3+, Gt(ROSA)26Sortm1Sor/Gt(ROSA)26Sor+ (more )
Note: Conditional mutant.
