Scientists have reported new insights gathered from a single gene that could one day be used to help adults grow a new set of teeth. Scientists from the University of Rochester bred mice that lacked the oddskipped related-2 (Osr2) gene. They noted that mice that lacked the gene grew an extra set of teeth next to their molars in similar fashion to sharks and other non-mammals. "It's exciting. We've got a clue what to do," Dr. Songtao Shi of the University of Southern California School of...


Word of the Day
monteith
