REHOVOT, Israel, Sept 7 (Reuters) - Scientists in Israel have created a model of a human embryo from stem cells in the laboratory, without using sperm, eggs or a womb, offering a unique glimpse into ...

The embryos cannot develop into humans, and are being used to study development in outer space.

A researcher holding human embryonic stem cell cultures in 2004. In the new research, scientists use human stem cells to make models similar to human embryos. The models cannot develop into fetuses.

The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the embryo model had a yolk sac and a proto-placenta, resembling a state that real ...
