histochemical Distribution of Glycogen and Alkaline Phosphatase in Placenta of Golden Hamster

Abstract
Glycogen and alkaline phosphatase were studied histochemically in the placenta of the golden hamster (Mesocricetus auratus).
The results were summarized as followings:
1. The histochemical distribution of glycogen and alkaline phosphatase was described in the various cells of both the placenta and uterus from implantation (5 days past coitum) parturition.
2. Glycogen appeared in the extraembryonic ectorm of the implanting ovum and increased gradually in the ectoplacental cone with the development of the placenta.
3. Glycogen granules began to accumulate in the labylinthine trophoblast of chorioallantoic placenta at 10.5 days and in the endodermal cells the visceral yolk sac sac at 10 days, respectively, and in these both cells glycogen increased gradually until the 13 days post coitum and after this time decreased progressively.
4. Alkaline phosphatase activity was high in the labyrinth, junctional zone and decidua, but was not observed in the yolk sac and trophospongium.
