There are different blood types: A, B, AB, and O, with each also being Rh-positive or Rh-negative. Knowing your blood type is important for safe blood transfusions and organ transplants. Type ...

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 ...

It has only recently become known that two parallel systems of blood formation exist in the body, originating from different precursor cells. Researchers at the German Cancer Research Center (DKFZ) ...

Hematopoietic stem cells (HSCs) are rare cells tucked away in the bone marrow. They hold the unique capability to produce every type of blood cell, from oxygen-carrying red blood cells to ...

Red blood cells transport oxygen throughout your body, including to vital organs and tissues. They also help your body get rid of carbon dioxide. Too little or too many red blood cells may be ...

The way in which blood stem cells evolve over a lifespan differs greatly between humans and mice, new research reveals. The findings provide a new understanding of the critical factors that influence ...

Chimpanzees and bonobos have mainly type A blood, while orangutans have A, B, AB, and O. Gorillas, however, appear to have blood types that do not fit the ABO system. In all great apes, red blood ...

Researchers at the Francis Crick Institute have identified genetic changes in blood stem cells from frequent blood donors that support the production of new, non-cancerous cells. Understanding the ...
