Stanford has successfully engineered a human uterus lining (endometrium) to be capable of embryo implantation — the first step to creating an artificial womb. On Tuesday, three studies published in ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

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 ...

Every human life starts with a risky and delicate event—a microscopic embryo finding a place to settle inside the uterus. If this process fails, pregnancy never begins, no matter how healthy the ...

Ancient DNA is turning human evolution into a crime scene reconstruction, and one of the prime suspects is a herpesvirus that ...

In recent years, Singapore has invested heavily in developing its biomedical industry. Of particular interest for policymakers are new assisted reproductive technology (ART) platforms and the related ...

Have you ever looked at a human embryo and thought, “That kind of looks like a fish”? If you haven’t, you might be surprised to learn that, in a way, we all begin our lives like this. The idea that ...
