Researchers from the University of Cambridge and Caltech have created model mouse embryos from stem cells—the body's master cells, which can develop into almost any cell type in the body—that have ...

Synthetic embryos made from mouse stem cells have been coaxed into developing the beginnings of a brain and a beating heart while grown in the laboratory. The result is an embryo-like structure that ...
