In recent years, the field of stem cell and developmental biology has seen remarkable breakthroughs that have deepened our understanding of how organisms grow, age and regenerate, with major ...

Red blood cells (RBCs), traditionally regarded as passive oxygen carriers, are now recognized as highly dynamic regulators of immune and vascular ...

A new study describes a technique that rejuvenates aging blood-forming stem cells and could help reduce the risk of age-related blood disorders.

Researchers have identified a previously unknown biological process that causes tissue and organ damage in conditions where oxygen is low, such as heart attacks and strokes. The study suggests that ...

A vivid new image is taking shape in the world of cell biology: Imagine bacteria adhering to the surface of a cell, perhaps at the site of an injury or wound. In response, a white blood cell arrives ...

Cornell researchers have uncovered a built-in molecular "gate" that controls the production of the molecule nitric oxide, a crucial signaling molecule throughout biology that in humans helps regulate ...

Stem cells in most organisms typically take cues from adjacent cells. But new research from the Stowers Institute for Medical Research has found that stem cells in the freshwater planarian Schmidtea ...
