The 14-day limit on scientific study of children conceived in vitro is already abhorrent, and any attempt to extend it should ...

Researchers have used stem cells to create models that resemble human embryos at two weeks old, but bypass the earliest developmental stages — paving the way for studies that are not possible in ...

Lab-engineered human embryo models created from stem cells provide a look at development beyond the first week. But they raise ethical questions.

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 ...

About 1% of the mixture began the journey of spontaneously assembling themselves into a structure that resembles, but is not identical to, a human embryo.

Scientists have created synthetic blobs that resemble a 14-day-old human embryo for the first time, meaning they can study embryo development beyond a particularly tricky period of pregnancy ...

They produced embryo models up to 14 days old, which is the legal limit for human embryo lab research in many countries, and the point at which organs like the brain begin to develop.

Stem cell biologist Jacob Hanna, a member of the 2024 #STATUSList, predicts human embryo models could pave the way to organ transplants.

This week, research published in the journal Nature detailed a model of a 14-day old human embryo created without using sperm or eggs. The hope is to shine a light into a previously unavailable window ...

Because of medical and ethical challenges, there’s much we don’t know about the first few weeks of human embryo development, says biologist Jacob Hanna of Israel’s Weizmann Institute of ...

Scientists have created the synthetic human embryos - using no eggs or sperm - provoking deep ethical questions, according to reports. The synthetic embryos - only days or weeks old - could help ...

Scientists have grown an entity that closely resembles an early human embryo, without using sperm, eggs or a womb. The Weizmann Institute team say their "embryo model", made using stem cells ...
