Scientists in the UK say they’ve pulled off a feat of genetic engineering: creating a “synthetic” mouse embryo without the need for egg or sperm cells. The embryos were created with stem cells instead ...

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 8 ½ days after fertilization ...

Scientists were able to grow "synthetic embryos" without the need sperm, eggs, or a womb. Studying these structures in mice could teach us how to grow organs for transplantation. Making human babies ...

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 ...
