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 ...

Scientists can now create embryo-like structures from animal and human stem cells in the lab, and recently, researchers unveiled the most advanced human embryo models yet, which resemble natural ...

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 ...

When Berna Sozen, PhD, assistant professor of Developmental Stem Cell Biology at Yale, was in her first weeks of pregnancy, she couldn’t help but wonder about what exactly was going on in the “black ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life. But studying this marvel of intricate and layered biological processes in people faces ...

REHOVOT, Israel (Reuters) - Scientists in Israel have created a model of a human embryo from stem cells in the laboratory, without using sperm, eggs or a womb, offering a unique glimpse into the early ...

Researchers are studying development of human pre-implantation embryos in an effort to improve success of embryo growth and development.

Scientists have successfully created immature human egg-like cells from skin-derived stem cells, a significant step in ...

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 ...

Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...
