Normal endometrium
Secretory phase Age 46 - XY

Continuous tomographic image in vertical direction of human endometrium in secretory phase.
The endometrial glands showed serrated and branching morphogenesis. The thin branches of glands commuted complicatedly in the stratum basalis. Some occluded glands which rose up from bottom of endometrium and swelled up without reaching luminal epithelium were detected.
3D reconstitution of human endometrium imaged by light-sheet microscopy.
Yellow: cytokeratin 7, Blue: autofluorescence
