Angiogenesis

Engineered microvessels can form bends and T-junctions, like this one. The blue dots are t...

A team of bioengineers at the University of Washington has developed the first structure for growing small human blood vessels in the laboratory. The vessels behave remarkably like those in a living human and offer a better and much more modular approach to studying blood-related diseases, testing drugs and, one day, growing human tissues for transplant.  Read More

It's a sad reality of our time that breast cancer affects more women around the world than any other form of cancer. Even more disturbing is the fact that up to ten years after surgery, the cancer returns in nearly 20 percent of those deemed to have had successful tumor-removal operations. Now, researchers at Brown University (BU) in Providence, Rhode Island, led by engineering professor Thomas Webster, have developed an implant which they believe can appreciably lower that relapse rate by simultaneously inhibiting cancer cell growth and attracting healthy breast cells.  Read More

In spite of numerous medical breakthroughs ranging from heart transplants to bypass surgery, cardiovascular disease still tops the list as the leading cause of death in developed countries. Key among the many problems that trouble our hearts is something called myocardial ischemia disease (MID), a condition that leads to reduced blood flow in the vessels of the heart and lower extremities and, frequently, corrective surgery. Now, University of Texas at Austin (UTA) biomedical engineer Aaron Baker and his research team have developed a method that may speed up the body's ability to grow new blood vessels (a phenomenon called angiogenesis), and best of all, no surgery is required. That's potentially great news for the nearly 27 million folks in the U.S. alone who chronically suffer from MID.  Read More
