Distribution of desmoplakin I/II in endometrial cells of mice in the artificially induced decidua

Abstract

The decidual reaction is characterized by the redifferentitation of the endometrial connective tissue into a tissue with epithelioid features formed by decidual cells. An ultrastructural study showed a special type of junction formed between differentiating (predecidual) cells of the mouse from day six of pseudopregnancy onward. These contacts share ultrastructural characteristics of both desmosome and adherens junctions. These junctions have usually been classified as desmosome-like. In the present work, besides the ultrastructural analysis, we investigated with light microscopy the presence of desmoplakins I and II, using streptavidin-biotin immunoperoxidase technique. We found a positive punctate staining around predecidual cells while a scarce reaction was observed in the other regions of the uterus. These results suggest that these junctions belong to the desmosome family.

Adherens Junctions

An adherens junction is defined as a cell junction whose cytoplasmic face is linked to the actin cytoskeleton. They can appear as bands encircling the cell (zonula adherens) or as spots of attachment to the extracellular matrix (adhesion plaques). Adherens junctions uniquely disassemble in uterine epithelial cells to allow the blastocyst to penetrate between epithelial cells. Discover the latest research on adherens junctions here.
