« Les premiers stades de l’œuf humain » par Auguste d’Eternod publiés il y a cent ans dans les Comptes Rendus de l’Association des Anatomistes

Abstract

The development of the embryo and foetus fascinates, but its study in humans is difficult because of both technical and ethical problems. Auguste d'Eternod, Swiss embryologist, published in 1913an article entitled "The early stages of the human egg" in the Comptes Rendus de l'Association des Anatomistes, the ancestor of the journal Morphologie. This work is focused not only on the early stages of development: fertilization, cleavage of the egg, blastocyst formation, gastrulation, but also on the extra-embryonic processes characteristic of mammals. On the occasion of the centenary of the publication of this work, I propose a critical review by placing the data published in the literature and historical context of the time. Finally, I try to extract from these observations the concepts that are still used today by embryologists.
