Morphology of stromal and epithelial endometrial cells after culture in presence of progesterone (200 nM). a Decidualised stromal cells after 7 days in culture in presence of 200 nM progesterone. Well-preserved cells with normally configured nuclei (N) containing glycogen and lipid deposits. Magnification, ×7,600. b Epithelial cells after 7 days in culture in presence of 200 nM progesterone. In contrast to the control culture without the steroid hormone (Fig. 3), the intercellular contacts are still well established even after the long culture period.
