Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into synthetic uterine tissue—revealing a key stage in reproduction. The resulting ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

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. The ...

Scientists can now create realistic human embryo models in the lab, leading some to suggest that we rethink how we legally define an embryo. When you purchase through links on our site, we may earn an ...

Using human stem cells, scientists have created human embryo-like structures inside petri dishes. These lab-grown blobs develop multiple structures that mimic a human embryo after implantation into ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Scientists have grown a scalable new embryo-like model that unshrouds some mysteries of early human development, including blood cell formation, or hematopoiesis—a first for the field. In an article ...

Ali Brivanlou slides open a glass door at the Rockefeller University in New York to show off his latest experiments probing the mysteries of the human embryo. "As you can see, all my lab is glass — ...

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 ...

The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the embryo model had a yolk sac and a proto-placenta, resembling a state that real ...

A research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus. “They are not identical,” said Magdalena Zernicka-Goetz, a ...
