Stem cells are precursors of a variety of different cells: They can turn into anything from blood to bone to muscle. Human blood stem cells, known as hematopoietic stem cells, are the forerunners of ...

A study led by Brazilian researchers has reconstructed the brain environment in the lab, revealing for the first time live interactions between cancer and healthy tissue, with the potential to reshape ...

Every person walking the planet carries roughly 37 trillion cells, and nearly every one of those cells holds an identical copy of that individual’s DNA. That number, once loosely pegged at 10 trillion ...

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 ...

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 ...

Scientists have discovered a method of helping human stem cells thrive in an animal embryo—a key development in efforts to grow human organs in animals for medical transplants. A study by UT ...

For years, scientists have been able to print living tissue. The problem is that most of it looks more like a sparse sketch than a real organ. In the human body, cells are packed tightly together, ...

Mount Sinai researchers have published the first organ-wide human skin spatial atlas from across the body. It provides an unprecedentedly detailed view of healthy human skin, revealing cellular ...

A new organelle has been discovered in human cells — and scientists call it a "hemifusome." Like the full-size organs in our bodies, the organelles within cells are specialized structures that carry ...
