Results
Specimen GUDMAP:11428: embryonic day 13.5 (more )
Note: Labeling was visualized using BM purple. This specimen annotates metanephros. Expression pattern for female was identical but images not shown.
Structure Level Pattern Image Note
TS21: urinary system mesentery Absent GUDMAP:11428
TS21: ureter Absent GUDMAP:11428
TS21: metanephros Absent GUDMAP:11428
TS21: primitive bladder Absent GUDMAP:11428

Specimen GUDMAP:11429: embryonic day 13.5 (more )
Note: Labeling was visualized using BM purple. Male and female were examined; only the male is shown. Annotators reported the female expression pattern in the whole urogenital tract is identical to male.

TS21: epithelium of phallic urethra of male Ambiguous GUDMAP:11429
TS21: proximal urethral meatus of male Ambiguous GUDMAP:11429 expression possible
TS21: mesenchyme of male preputial swelling Ambiguous GUDMAP:11429 expression unclear due to the strong expression in the surface epithelium.

Specimen GUDMAP:11430: embryonic day 10.5 (more )
Note: Labeling was visualized using BM purple.
Structure Level Pattern Image Note
TS17: genitourinary system Absent GUDMAP:11430
