Researchers at the Francis Crick Institute 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 ...

A MedUni Vienna study team led by geneticist Markus Hengstschläger has used a stem cell model to model the earliest stages of embryonic development and to characterize the membrane that surrounds the ...

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 ...

Having a baby in space may require a bit more direction, with new Adelaide University research revealing the navigational abilities of sperm are negatively impacted by a lack of gravity. Researchers ...
