Nano-bumps could help repair clogged blood vessels

Biomedical engineers at Purdue University have shown that "vascular stents" used to repair arteries might perform better if their surfaces contained "nano-bumps" that mimic tiny features found in living tissues. The researchers already have shown in a series of experiments that bone and cartilage cells in petri dishes attach better to materials that possess smaller surface bumps than are f...

Unexpected lock and key mechanism found for the assembly of tumor blood vessels

A critical lock and key mechanism that allows the final step in the completion of new blood vessel formation has been identified by a University of California, San Diego (UCSD) School of Medicine team in research that promises to lead to a new way to halt tumor growth by cutting off the tumor blood supply. The research team led by Judith Varner, Ph.D., Associate Professor of Medicine at UC...

Stanford doctors advance in bid to turn mice stem cells into blood vessels

Researchers at the Stanford University School of Medicine have taken a first step toward growing blood vessels from stem cells that could eventually be transplanted into living organisms. Starting with embryonic stem cells derived from mice, surgical resident Oscar Abilez, MD, and colleagues have successfully differentiated the stem cells into myocytes, one of the building blocks of blood...

UT Southwestern researchers unravel control of growing blood vessels

Researchers at UT Southwestern Medical Center have discovered a basic mechanism by which smooth muscle cells that line the blood vessels can grow ?sometimes abnormally ?suggesting methods of treatment for various coronary diseases. Abnormal growth of cells inside blood vessels is involved in hypertension, coronary artery disease, tumors called leiosarcomas and other conditions. "By underst...

Bare metal stents deliver gene therapy to heart vessels with less inflammation in animal studies

Improved materials may allow stents, tiny metal scaffolds inserted into blood vessels, to better deliver beneficial genes to patients with heart disease, by reducing the risk of inflammation that often negates initial benefits. The new technique, using a compound that binds in an extremely thin layer to bare metal surfaces, may have potential uses in other areas of medicine that make use of metal...

Drugs disrupt formation of blood vessels

Scientists have made a signficant step forward in their attempt to starve cancer tumours by stopping the growth of the blood vessels that feed them nutrients. Four drugs that disrupt angiogenesis - blood vessel formation - have been shown for the first time to be effective. It also provides the first indication that the drugs, known as angiogenesis inhibitors, vary in effectiveness depending on t...

Stem cells form blood vessels

Many scientists have found new ways to repair damaged arteries and ailing hearts have coaxed stem cells from a human embryo into forming tiny blood vessels. According to Robert Langer, leader of a laboratory team at the Massachusetts Institute of Technology, this is the first time human embryonic stem cells have been nurtured to the point where they will organize into blood vessels that could nou...

Chemical in Vegetables Keep Blood Vessels Healthy

Nitrates, a chemical found in vegetables like spinach and lettuce, may be responsible for keeping blood vessels healthy, says a new study//. Past studies have shown that a diet rich in fruits and vegetables can reduce blood pressure. But it has been difficult to determine exactly which nutrients in fruits and vegetables are responsible for these blood-pressure-lowering ef...

How Bloods Vessels are Linked Together?

The Scientists at Karolinska Institutet have discovered a heretofore-unknown mechanism for -how the body links together its blood vessels.// New blood vessels are formed when a "shoot" sprouts from an already existing vessel. These shoots lengthen, branch off and contact other vessels as they form communicating networks of channels. The process is called "angiogenesis" and is importan...

NCI Researchers Discover Genes That Are Turned on at High Levels in Tumor-associated Blood Vessels of Mice and Humans

BETHESDA, Md., June 11, 2007--A team of researchers at theNational Cancer Institute (NCI), part of the National Institutes ofHealth (NIH), has uncovered a set of genes that are turned on, orexpressed, at high levels only in the blood vessels that feedtumors in mice and humans. These genes, and the proteins theyencode, are important new potential targets for novel drugs thatcould selectiv...
