Sources for comparative studies of placentation I. embryological collections

Abstract

A rich source of material for comparative studies of the placenta is the collections made by pioneers in the field such as H.W. Mossman, A.A.W. Hubrecht and J.P. Hill. This overview gives a brief description of collections known to be available and information on how each can be accessed. Included are some of the major series of human and animal embryos, such as the Boyd and Carnegie collections, as these also house placental material.
