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 ...

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly. Two of the first physical structures to form in the embryo are ...

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

Most people have heard of stem cells. They are often described as "miracle" cells –ones that can grow into any other type of cell in our bodies, promising revolutionary medical treatments. However, ...

Scientists found that embryonic skin cells “whisper” through faint mechanical tugs, using the same force-sensing proteins that make our ears ultrasensitive. By syncing these micro-movements, the cells ...

LONDON (Reuters) - A decision by one of the biggest names in stem cell research to throw in the towel will not stop other pioneering work that could yet produce cures for blindness and help mend ...

BIRMINGHAM, Ala. – Millions of adults have atrial fibrillation — an irregular beating of the upper chambers of the heart that yields increased risk of heart failure, stroke and death. Many genetic ...

The crustacean Parhyale hawaiensis (P. hawaiensis) organizes its cells in a grid-like pattern during embryo development, relying on grid patterning rather than chemical signals to dictate cell ...
