PRACTICAL WORKSHOP IN HISTOLOGY, CYTOLOGY AND EMBRYOLOGY - 2016

Section 3. GENERAL EMBRYOLOGY. HUMAN EMBRYOLOGY.

Slide 23. Allantois.

Staining: hematoxylin and eosin.

Magnification: x80.

This is a whole mount preparation, which is a thin membrane viewed from the surface. Since the wall of the allantois is based on extraembryonic mesoderm lined on the inside by endoderm, we can observe numerous overlapping nuclei of mesenchymal and epithelial Cells

(1) and Blood Vessels (2).
