Scientists have been working on the artificial production of blood for several decades. Now, researchers from the University of Konstanz and Queen Mary University of London have taken an important ...

Ancient viral remnants in the human genome are activated during pregnancy and after significant bleeding in order to increase blood cell production, an important step toward defining the purpose of ...

A team of researchers claims to have found a common bacteria that can easily manipulate the enzymes present in blood supplies to turn it into a universal donor type. Such a process, if scaled up for ...

The blood system changes over time: a subset of stem cells outcompete their neighbors and gradually take over blood production. In addition, the blood stem cell reservoir shrinks and becomes dominated ...

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 ...

A study in the journal Nature explains how age reshapes the blood system. In both humans and mice, a few stem cells, or "clones," outcompete their neighbors and gradually take over blood production.

If CXCR4 is removed from the cells, red blood cell development stops at subsequent stages, and bone marrow production drops severely. That loss helps to confirm just how important the CXCL12-CXCR4 ...
