NSFL warning
Search for "Teratoma" if you want to see what happens when this goes wrong.
This is something different. This treatment is not for replacing teeth that were somehow lost, but for people where one or more teeth didn't develop in the first place.
It says in the article it will treat "all forms of toothlessness"
In other earlier reports it is also mentioned that the successes in animal trials also were with congegeniaal tooth deficiency. So the hopes of this researcher are not backed by results. And though I'm no expert on any field related to this, I can't see how this would work for people who lost teeth.
Quick edit; an earlier source
I've read the studies related to USAG-1, the molecule in question. Most of them mention that the treatment would also be applicable to normal mice (and hopefully humans). I'm guessing the widespread mentions of congenital tooth deficiency is due to funding or other criteria they want to meet.
