Summary:
University of Pittsburgh researchers have developed a minimally invasive method of delivering growth factor to regrow blood vessels. The research, published this week in the Aug. 1 issue of the journal Proceedings of the National Academy of Sciences, could be used to treat heart disease, the most common cause of death in the Western world.
When the researchers injected their growth factor compound under the skin of mice, they saw something amazing: New blood vessels grew, and large ones, not just tiny capillaries. Moreover, the structures stuck around. At least a month later, after only one injection of the growth factor complex, the new blood vessels were still there.
