STORY: This looks a lot like a human embryo. But it was created without sperm, eggs, or a womb. It was made in a lab, by a group of scientists in Israel. And what they've created so far offers a new ...

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 ...

Implantation, one of the most poorly understood phases of early human development, occurs in the depths of the womb, at a time when embryos are microscopic, fragile, and well out of reach. Until ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...

A team of scientists have successfully created authentic models of a human embryo using stem cells, and successfully grown them outside of a womb until key embryonic features such as a yolk sac, and ...
