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...

Cancer Cells Forming Blood Vessels Send Their Copper to the Edge

Researchers have discovered new information about a link between the growth of blood vessels critical to the spread of cancer and the copper in our bodies. // Growing new blood vessels from existing ones — a process called angiogenesis — is important in growth, development and wound healing. But it also enables the spread of tumors throughout the body, so researchers have been scrambli...

Targeting Sugar on Blood Vessels may Inhibit Cancer Growth

In a study that could point to novel therapies to prevent cancer spread, or metastasis, researchers at the University of California, San Diego (UCSD) School of Medicine have targeted a sugar that supports blood vessel growth in the tumor. Lung cancer is the most common cause of cancer death and an area where novel therapies to block metastasis are desperately needed, according to f...

Scientists Develop Artificial Blood Vessels for Vascular Grafts in Mice

Researchers at the University of Pittsburgh School of Medicine have developed artificial blood vessels, which may have significant implications for the treatment of heart and kidney disorders . The vessels, made from muscle-derived stem cells (MDSCs) and a biodegradable polymer, exhibit extensive remodelling, and remain free of blockages when grafted into rats. The sap...

New Blood Vessels can Be Created from Bone Marrow Stem Cells: Study

Scientists have developed a way to produce blood vessels by engineering tissues from bone marrow adult stem cells . Researchers at the University at Buffalo Department of Chemical and Biological ngineering say that the bone marrow is an excellent source of adult stem cells, containing smooth muscle and endothelial cells, and add that these stem cells can be used in regenerative medi...
