[Chimeric embryos and pseudo-embryos: An alternative to human embryos for research].

Abstract

L’étude du développement humain est indispensable afin d’approfondir nos connaissances et, à long terme, perfectionner nos stratégies thérapeutiques dans les domaines de la médecine de la reproduction et de la médecine régénératrice. Face à la limite d’accès aux embryons surnuméraires et à l’interdiction d’en créer de nouveaux seulement à des fins de recherche, deux stratégies alternatives peuvent être proposées pour étudier le développement embryonnaire humain. La première consiste à fabriquer des pseudo-embryons ou blastoïdes. La seconde consiste à créer des embryons chimères homme/animal par injection de cellules souches pluripotentes, ES ou iPS, dans des embryons d’animaux. Nous expliquons ici l’importance de ces nouveaux paradigmes expérimentaux pour étudier le développement humain, et leur complémentarité.

The study of human development is essential to further our knowledge and to improve our therapeutic strategies in the fields of reproductive and regenerative medicine. Given the limited access to supernumerary embryos and the prohibition on creating new ones for research, two alternative strategies can be proposed to study human embryonic development. The first is to create pseudo-embryos or blastoids. The second is to create human/animal chimeric embryos by injecting pluripotent stem cells, ES or iPS, into animal embryos. We explain herein the importance of these new experimental paradigms for studying human development and their complementarity.
