Abstract

The placentae and uterus of the golden hamster representing days 6-16 (term) were stained for glycogen with periodic-Schiff and Best's carmine, and checked with diastase. Glycogen is present in consistently great quantities in the Träger, trophospongium, myometrium, uterine glands, and tunica media of blood vessels. Glycogen appears in great quantities in the visceral yolk sac on day 11 and remains as such until term. Glycogen was observed in small quantities in the proximal area of the parietal yolk sac entoderm which adjoins the visceral yolk sac, as well as in the splanchnic mesoderm of the visceral yolk sac, from day 11 to term. Endometrial glycogen concentration decreases progressively in quantity during gestation as the endometrial cells become compressed. There is slightly less glycogen in the interlocular than in the locular regions of the uterus. The residual trophoblast cells in the labyrinth stain for glycogen throughout the remainder of gestation. Glycogen may occasionally be noted here and there in the uterine epithelium.
