Each year, about 185,000 people in the United States undergo amputation. Nearly half of those are due to injured blood vessels cutting off circulation to a limb. Surgeons can transplant an intact vein ...

How do blood vessels stay strong, flexible, and responsive to the body's changing need for oxygen and nutrients? The answer lies not only in biology—but also in physics. Researchers at Åbo Akademi ...

Organelles called mitochondria are transferred to blood-vessel-forming cells by support cells. Unexpectedly, these mitochondria are degraded, kick-starting the production of new ones and boosting ...

The formation of blood vessels is a complex process involving the interplay of proteins and mechanic forces. In two studies, a research team has uncovered new mechanisms in blood vessel formation. The ...

Scientists have identified two subtypes of lung blood vessel cells. One subtype expresses more genes involved in inflammation and the regulation of the immune response; the other expresses more genes ...

The brain relies on real-time delivery of oxygen and nutrients through its microvasculature, which threads through neural ...

Scientists at the University of Illinois Chicago have analyzed gene expression data from more than 35,000 blood vessel cells from the lungs of mice and identified two subtypes. One subtype, which they ...
