Blood clots can form when substances in the blood clump together. If they block blood vessels, they can prevent blood from flowing to important organs. Blood thinners help prevent clots from forming and growing larger, but they can also cause bleeding. Researchers wanted to see whether a new compound, called MPI 8, could help prevent blood clots without bleeding. While the research was done in mice, with further study, MPI 8 could one day also be used to treat patients. Learn more about this and other blood clot research
