Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

The most advanced lab-made human embryo models look like the real thing — they resemble, though don't perfectly replicate, natural embryos about 14 days into development. These lab-made embryo models ...

A baby boy born last week to an Ohio couple developed from an embryo that had been frozen for more than 30 years in what is believed to be the longest storage time before a birth. In what's known as ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...

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 ...
