Abstract | This study deals with the histochemistry of the changing patterns of glycogen in the uterus and extra-embryonic membranes of the golden hamster (Mesocricetus auratus Waterhouse). The uterus and extra-embryonic membranes of the golden hamster representing days of gestation from six to term were stained with periodic acid-Schiff and Best's carmine. Diastase was used to check the glycogen-staining efficiency of these two procedures. Non-pregnant and post-partum uteri (day one) were also stained and checked with diastase for comparison. Glycogen is present in great quantities in the Träger, trophospongium, myometrium, uterine glands, and blood vessel tunica media. No observable increase or decrease in glycogen content was observed in these tissues. Glycogen appears in the visceral yolk sac on day eleven and remains in great quantities until term. Glycogen may be observed in small quantities in the parietal yolk sac entoderm near the visceral yolk sac, and in the visceral yolk sac splanchnic mesoderm from day eleven to term. Endometrial glycogen concentration appears to decrease as gestation proceeds, and as the endometrial cells become compressed. There appears to be slightly less glycogen in interlocular than in locular uterine regions. The residual trophoblast cells in the labyrinth stain for glycogen throughout gestation. Glycogen may occasionally appear in uterine epithelium. Some theories on glycogen storage and transport are reviewed. |
