Studying these structures in mice could teach us how to grow organs for transplantation. Making human babies that way remains a distant prospect, fraught with ethical problems. Scientists grew ...

Scientists have created “synthetic” mouse embryos from stem cells without a dad’s sperm or a mom’s egg or womb. The lab-created embryos mirror a natural mouse embryo up to 8½ days after fertilization, ...

Scientists have been able to create stem cells that can mimic the early stages of mouse development. The researchers used only reprogrammed stem cells, not a fertilized egg, to create a synthetic ...

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 ...
