He has examined the birth and origin of endothelial cells, which form the thin layer that lines the interior surface of blood vessels
Unfortunately, malignant tumours are also capable of growing new blood vessels
to receive oxygen and nutrients.
The formation of new blood vessels
is known as angiogenesis and is one of the main driving forces behind cancer.
and his colleagues covered iron nanoparticles with a peptide they designed to adhere to proteins found only in tumor blood vessels
Stroke can be subdivided into two types: * Ischemic stroke: caused by blockage of the brain blood vessels
due to clot formation and accounting for approximately 84% of all stroke cases.
One possibility is that arsenic may alter the normal vasomotor tone of blood vessels
, which rises from contractility of vascular smooth muscle cells.
But the findings raise hope that such transplants might be used to treat several common eye diseases that involve abnormalities in the blood vessels
of the retina, the light-sensitive lens located in the back of the eye.
Finally, they withdraw the tube and seed each nascent vessel with cells taken from the lining of one of the patient's blood vessels
However, the diversity of cardiovascular diseases arising from chronic arsenic exposure also raises the possibility that arsenic may alter the normal functioning of blood vessels
, which are involved in various cardiovascular disorders.
Last year, researchers at Laval University in Quebec, Canada, made the first blood vessels
sculpted entirely from human cells.
Of these, Isner said 16 have responded by growing new blood vessels
that carry blood around the blockages.
About 85 percent of strokes are caused by clots blocking blood vessels
in the neck or brain.
The researchers looked at angiogenesis - the body's formation of new blood vessels
from existing blood vessels
- and how some blood proteins are involved in that process and affect blood vessel
growth during a study.
Either of these conditions can set in motion a chain reaction that builds up scar tissue and, over years, creates new, weak blood vessels
that leak and obscure vision.
High blood pressure can cause blood vessels
to age before their time, new research suggests.
