Finklestein is working with Creative Biomolecules, a Massachusetts company, to set up safety and efficacy trials of OP-1 in humans. Results so far indicate that bFGF and OP-1 are equally effective. OP-1 makes the catcher's mitt grow larger, increasing chances of the pitch reaching home plate. It may turn out that it's best to use them together. It also could be kept at hand when people at increased risk for stroke undergo heart surgery.
Growth factors are a hot area of research.
