Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

Why do pregnancies last longer in some species than others? Researchers have found the clock that sets the speed of embryonic development and discovered the mechanism is based on how proteins are made ...

Researchers at the Institute for Bioengineering of Catalonia (IBEC) in collaboration with the Dexeus University Hospital have captured unparalleled images of a human embryo implanting. This is the ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

A new King's-led study, published in the Proceedings of the National Academy of Sciences, has found that a single factor (a protein coding gene known as Sox8) can make non-ear cells adopt ear ...

A team at the University of Cambridge has announced making the first human “synthetic embryos” – embryo-like structures made from stem cells – that have been grown to a stage equivalent to just past ...

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 method for culturing fertilized chick eggs without their shells. The eggs were placed in an artificial culture vessel made of transparent film, allowing for real-time ...
