Changes of the Golgi apparatus and lysosomes during decidualization in mice.
The Golgi apparatus of the endometrial stromal cells of pregnant mice increases in size simultaneously with the differentiation of stromal cells into decidual cells. The activity of acid phosphatase in this organelle increases during this stage. On the other hand, the involuting decidual cells show morphological and cytochemical signs of Golgi regression (dilated cisternae, lack of enzymatic activity) together with the finding of numerous, pleomorphic lysosomes that have intense cytochemical label. These results confirm morphological data suggesting that decidual cell death occurs by autophagic degeneration.
