Every face is unique. Genetics helps to determine our features, but sometimes genes have errors, which, in early fetal development, can result in babies with facial differences such as a cleft lip or ...

How can we reliably and objectively characterize the speed and various stages of embryonic development? With the help of artificial intelligence! Researchers present an automated method. Animal ...

Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

The mystery of early embryonic communication is starting to be unraveled thanks to a new stem cell-based model.

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

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 ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...
