Tiny tool to control growing blood vessels opens new potential in tumor research

Researchers at Uppsala University have developed a **new tool** that makes it possible to study the signals in the body that control the generation of **blood vessels**. The researchers' findings, published in the new issue of Lab on a Chip, enable scientists to determine what signals in the body attract or repel blood vessels, knowledge that is extremely interesting in **tumor research**. The new invention is a tiny cell cultivation chamber of silicon plastic in which researchers can cultivate blood-vessel-rich tissue and simultaneously create targeted signals that instruct the vessels to go in a certain direction. This is of great interest to the international research world. "Uppsala University":[ http://www.uu.se/news/news_item.php?typ=pm&id=504]
