For decades, the idea of growing human tissue inside another species sounded like something that belonged in a science fiction movie. Today, laboratories are exploring a far more practical version of ...

University of Zurich researchers found that a one-hour treatment with activated protein C keeps human blood stem cells in a ...

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 ...

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 ...

Every second of every day, the human body replaces roughly two million red blood cells that have reached the end of their working lives. That relentless output, sustained around the clock inside bone ...

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 ...

T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on exquisitely timed molecular signals. Now researchers have captured one of 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 ...

Every cell in the human body carries the same 3 billion letters of DNA, yet a neuron, a heart muscle cell and a pancreatic beta cell each use that shared code to do entirely different jobs. How cells ...
