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 — ...

In the lab, it's easier to grow simple balls of cells than complex asymmetrical structures with two distinct ends—like the one million filtering units—nephrons—that make up a human kidney. But new ...

Development can be thought of as a journey. The journey begins at conception with a genetic roadmap to guide the way. As this journey continues through predictable stages of birth, infancy, childhood, ...
