Rare Disease’s DNA-Damaging Mutation Could Have Consequences for More Common Conditions
In their pursuit to discover the mechanism behind how RVCL does its damage, researchers found some clues to the DNA damage theory of aging
Research offers hope for preventing post-COVID ‘brain fog’ by targeting brain’s blood vessels
In a study of mice, researchers identified a mechanism that causes post-infection neurological problems
Advances in the differentiation of pluripotent stem cells into vascular cells
Blood vessels constitute a closed pipe system distributed throughout the body, transporting blood from the heart to other organs and delivering metabolic waste products back to the lungs and kidneys. Changes in blood vessels are related to
Fibroblasts in the penis are more important for erectile function than previously thought
Regular erections could be important for maintaining erectile function, according to a new study on mice published in Science by researchers at Karolinska Institutet.
Tubular tissue advance could pave way for lab-grown blood vessels
Innovative technology that creates ultra-thin layers of human cells in tube-like structures could spur development of lifelike blood vessels and intestines in the lab.
NEI Scientists publish recipe for making blood vessel cells from patient stem cells
Researchers at NIH’s National Eye Institute have published a detailed protocol for making three cell types that are key components to form blood vessels and capillaries.
Leaps in artificial blood research aim to improve product safety, efficacy
Researchers have made huge strides in ensuring that red blood cell substitutes – or artificial blood – are able to work safely and effectively when transfused into the bloodstream.
How nerve and vascular cells coordinate their growth
Nerve cells need a lot of energy and oxygen. They receive both through the blood. This is why nerve tissue is usually crisscrossed by a large number of blood vessels.
A dynamic duo of cells identified in lung blood vessels
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 involved in cell regeneration and proliferation. The findings could lead to better treatments for lung infections.

How Calcium Precisely Directs Blood Flow in the Brain
University of Maryland School of Medicine and University of Vermont researchers have shown how the brain communicates to blood vessels when in need of energy, and how these blood vessels respond by relaxing or constricting to direct blood flow to specific brain regions.
Unexpected discovery opens a new way to regulate blood pressure
A new discovery finds that zinc plays a critical and underappreciated role in blood pressure regulation, offering a potential new pathway for therapies to treat hypertension.

Robot Uses Artificial Intelligence and Imaging to Draw Blood
Rutgers engineers have created a tabletop device that combines a robot, artificial intelligence and near-infrared and ultrasound imaging to draw blood or insert catheters to deliver fluids and drugs. Their research results, published in the journal Nature Machine Intelligence, suggest that autonomous systems like the image-guided robotic device could outperform people on some complex medical tasks.
