Every day, your body replaces billions of cells—and yet, your tissues stay perfectly organized. How is that possible? A team of researchers at ChristianaCare's Helen F. Graham Cancer Center & Research ...

Every pregnancy depends on an organ that most people will never see. As organs go, the placenta — the tissue that surrounds a developing fetus — is a jack of all trades. It can filter toxins like a ...

The body's cells change their shape to close gaps such as wounds—with part of the cell flexing depending on the curve of the gap and the organization of cell-internal structures, a new study reveals.

Scientists have built a massive cellular atlas showing how aging reshapes the body across 21 organs. Studying nearly 7 million cells, they found that aging starts earlier than expected and unfolds in ...

We’re just beginning to decode this faint optical “signature of life” and what it could reveal about health, disease, and the ...

Collagen, the protein that builds skin, bones, tendons and organs, exists inside cells as a liquidlike droplet rather than the long, rigid rod seen in textbooks over the last half-century, according ...

Cancer is one of the leading causes of death worldwide, marked by the uncontrolled growth of abnormal cells. What makes it more dangerous is the ability of cancer cells to move quickly through the ...

For the first time in a mammal, researchers have chemically coaxed wound cells into forming new bone, joints, tendons, and ...

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 ...

A new study from The University of Texas at Arlington details a novel strategy for how the body clears out dead cells during stress, revealing unexpected roles for well-known stress-response genes-a ...
