Scientists Just Caught Human Embryo Implantation on Camera
Scientists recorded in 3D and in real time the exact moment a human embryo implanted itself in an artificial uterus, opening new avenues for treating infertility.
This process, which occurs within days of a sperm fertilizing an egg, had, until recently, remained virtually invisible—implantation was only known from still images, and it wasn’t possible to follow its development in real time. “We observe that the embryo pulls on the uterine matrix, moving and reorganizing it,” explained Amélie Godeau, coauthor of the research, which was published in Science Advances. “Our work consisted of providing technical advice and rigorously selecting the human embryos donated for research, ensuring they met the ideal conditions for the project,” said Miquel Solé, director of the Dexeus Mujer Cryopreservation Laboratory.
