Barriers between stem cells play a crucial role in human development—and offer a new potential route for fertility treatment SAN FRANCISCO, CA—As a human embryo grows, a set of molecules directs cells ...

Cell-to-cell junctions were visualized by ZO1-GFP, and the dynamics of cell junctions were captured by movies. When the cells indicated by * were spontaneously stretched, a continuous belt of cell ...

The emergence of gap junctions is a hallmark in the evolution of life from single-cell to multicellular organisms. For the first time, they enabled true social interactions between cells by allowing ...

Janelia researchers have uncovered a novel way that two of the structures inside cells—the endoplasmic reticulum (ER) and ...

Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in DNA's shape have an important influence on gene activity and energy production.

Scientists have uncovered a key role for the protein “Frazzled” in building and maintaining the rapid neural connections that allow fruit flies to react in milliseconds.

A new paper published today in Cell highlights how researchers have leveraged AI-based computational protein design to create a novel synthetic ligand that activates the Notch signaling pathway, a key ...
