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 ...

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 — ...

Janet Rossant is president of the Gairdner Foundation, and senior scientist emeritus at The Hospital for Sick Children, University of Toronto, Toronto, Canada. The first few weeks of a human embryo’s ...

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 ...

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

Over the past year or two, we have been exploring what we termed the origins—or the embryology—of human development. We examined the three pillars of development: Feelings (Affects), Language, and ...

When someone says the word embryo, what do you think of? Probably that picture you’ve seen a thousand times on a thousand different news articles: a translucent orb swelling with cytoplasm being ...

A small tissue fold in fly embryos, once thought purposeless, plays a vital role in stabilizing tissues. Researchers show that it absorbs stress during early development, and its position and timing ...

Researchers have created model embryos from mouse stem cells that form a brain, a beating heart, and the foundations of all the other organs of the body -- a new avenue for recreating the first stages ...
