Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...

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.

Scientists have grown a scalable new embryo-like model that unshrouds some mysteries of early human development, including blood cell formation, or hematopoiesis—a first for the field. In an article ...
