What happens in the first weeks after a human embryo implants in the uterus has been a black box. Now, biologists have had a chance to study this stage of development in detail for the first time. The ...

Using the fruit fly, scientists have constructed a complete and detailed single-cell map of embryo development. This research will also help scientists pursue questions like how mutations lead to ...

Researchers at the Babraham Institute have ‘listened in’ to the communication between the embryo and the womb lining at 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 ...

The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller cells at the margin—a size gradient that controls the timing of everything ...

The major objection to the use of embryonic stem cells for scientific research seems overcome by the promising development of a way to extract cells and propagate stem cell lines without killing the ...
