Novel bioelectric signals can cause stem cells to trigger melanoma-like growth in pigment cells

Biologists at Tufts University School of Arts and Sciences have discovered that a change in membrane voltage in newly identified "instructor cells" can cause stem cells' descendants to trigger melanoma-like growth in pigment cells. The Tufts team also found that this metastatic transformation is due to changes in serotonin transport. The discovery could aid in the prevention and treatment of diseases like cancer and vitiligo as well as birth defects.

Pericytes regulate blood-brain barrier

While the blood-brain barrier (BBB) protects the brain from harmful chemicals occurring naturally in the blood, it also obstructs the transport of drugs to the brain. In an article in Nature scientists at the Swedish medical university Karolinska Institutet now present a potential solution to the problem. The key to the BBB is a cell-type in the blood vessel walls called pericytes, and the researchers hope that their findings will one day contribute to new therapies for diseases like Alzheimer's and stroke.

Scientists discover 'switch' mechanism of lymphatic and blood vessel cells

Scientists at the University of East Anglia have made an important breakthrough in the way anti-cancer drugs are tested. A tumour cannot grow to a large size or spread until it has developed its own blood supply and leading research has looked for a way of halting capillary formation to stop tumours taking hold.But new findings published today in the Journal of Cell Science have shown that scientists testing such treatments may not have been studying exactly what they thought they were.

Study finds no link between AMD treatments and increase in cardiovascular complication

Newer treatments for age-related macular degeneration (AMD)-including an intravitreous (into the eye) injection of a chemotherapy drug and use of a related compound approved for use against the eye disease-do not appear to be associated with an increased risk of cardiovascular complications or death when compared with existing therapies, according to a report in the October issue of Archives of Ophthalmology, one of the JAMA/Archives journals.

Low-fat diet reduces risk of heart disease

Losing weight, especially among adults who are very heavy to obese, is a good way to prevent the onset of atherosclerosis, the artery-thickening condition that leads to potentially deadly heart disease. A diet that is low in either fats or carbohydrates can help reduce weight. But which one is the more heart-healthy?

'The Pittsburgh Protocol' enables reduction of multiple anti-rejection drugs after transplantation

The Pittsburgh Protocol is unique in utilizing bone marrow cells to enable reduction of the need for multiple anti-rejection drugs after transplantation. The University of Pittsburgh Medical Center is currently the only transplantation center in the world to offer it. An early report of the initial experience with the "Pittsburgh Protocol" in three recipients of upper extremity transplants was presented during the 2010 Annual Clinical Congress of the American College of Surgeons.

PDGF identified as key factor in proliferation and transformation of epicardial cells

In research that one day may lead to the discovery of how to regenerate tissue damaged by heart disease, investigators at Childrens Hospital Los Angeles have identified PDGF as a key factor in the proliferation and transformation of epicardial cells, one type of cell that surrounds heart muscle and contributes to vessels.

Way of VAD implantation can impact stroke occurrence

A surgical team from the University of Central Florida College of Medicine and Arnold Palmer Hospital for Children, Orlando, has presented findings from the first study to demonstrate that the way a ventricular assist device (VAD) is implanted can have an impact on whether or not a patient may have a stroke while the device is in use.
