    Summary

    This study details green monkey placentation, revealing superficial implantation and hemomonochorial classification. Findings clarify embryonic blood vessel development, refuting cytotrophoblast delamination origins.

    Area of Science:

    • Reproductive Biology
    • Primate Anatomy
    • Developmental Biology

    Background:

    • Primate placentation exhibits diverse adaptations.
    • Understanding non-human primate models aids human pregnancy research.
    • The green monkey (Cercopithecus aethiops) serves as a relevant model.

    Purpose of the Study:

    • To characterize early placentation in the green monkey.
    • To compare green monkey placental features with other macaques.
    • To investigate the cellular origins of embryonic blood vessels.

    Main Methods:

    • Light and electron microscopy were employed.
    • Gestational ages ranged from 18 to 30 days.
    • Histological and ultrastructural analyses were performed.

    Main Results:

    • Superficial, bidiscoid implantation observed.
    • Placentae classified as villous and hemomonochorial.
    • Epithelial plaque formation with glycogen-rich cells noted.
    • Embryonic blood vessels formed via mesenchymal cell attachment, not cytotrophoblast delamination.
    • Embryonic blood first seen in villi after day 22.

    Conclusions:

    • Green monkey placentation shares features with rhesus macaques.
    • Mesenchymal cells, not cytotrophoblast, form chorionic blood vessels.
    • Early placental development in green monkeys provides insights into primate embryogenesis.
