Chemical messenger controls bone growth in embryos, study finds

...e: The bones of mice lacking FGF 18 didnt begin to harden as soon as they should have. Ossification was delayed by about two days, which is a long time for mouse embryos, says Ornitz. That suggests that FGF 18 also influences a second receptor, probably FGF receptor 1 or 2. Ornitz and his colleagues now a...
