Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into collagen designed to mimic uterine tissue —a key stage in reproduction. “This will allow us to develop treatments specifically targeting implantation,

Scientists have captured a video showing the implantation of a human embryo for the first time, using a laboratory model of a uterus.

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first time—footage of human embryo implantation right as it’s happening.
