Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

STORY: This looks a lot like a human embryo. But it was created without sperm, eggs, or a womb. It was made in a lab, by a group of scientists in Israel. And what they've created so far offers a new ...

It’s still one of the biggest mysteries in science: How does a human cell — too small to see with the naked eye — divide and reproduce to ultimately become a human body made up of more than 30 ...

Ali Brivanlou slides open a glass door at the Rockefeller University in New York to show off his latest experiments probing the mysteries of the human embryo. "As you can see, all my lab is glass — ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

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 ...

Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life. But studying this marvel of intricate and layered biological processes in people faces ...

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 ...

Researchers have found a new way to produce human blood cells in the lab that mimics the process in natural embryos.
