Scientists create a ‘mini-womb’ 3D model on a microfluidic chip which could lead to treatments for women affected by ...

For decades, scientists have struggled to study this moment in humans because of ethical restrictions and limited access to ...

Scientists have sought to capture the first days of how a person comes to be, by recreating those early moments in a lab via models made up of induced pluripotent stem cells, or IPSCs. Subscribe to ...

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...

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 - ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Scientists have discovered a kind of “pause button” in early human development. This biological mechanism has long been known in other mammals, but its discovery in humans could aid IVF procedures.

Scientists at the Francis Crick Institute have generated human stem cell models 1 which, for the first time, contain notochord – a tissue in the developing embryo that acts like a navigation system, ...
