    Lots of hopium in the article. The base treatment seems to be for 2-7 years old missing teeths.

    I mean you can’t just inject some stuff and have a random tooth grow out.

      Well, that’s not actually the first thing they’re testing:

      Now, scientists will see just how similar, because humans will soon undergo a similar trial in September of this year. Lasting 11 months, this study will focus on 30 males between the ages of 30 and 64—each missing at least one tooth. The drug will be administered intravenously to prove its effectiveness and safety, and luckily, no side effects have been reported in previous animal studies.

      I’m guessing the idea is to catch teeth that could have developed but never did (hey, I’m missing one that way). Otherwise I’m not sure how they’d control which type and how many show up.

      Annoyingly there’s no English language link, so it’s hard to say. I’m not even clear on what they did with the ferrets.

          Ah, thanks!

          So the meat of this is actually the mouse models, looks like. Strains of mice with genetically missing teeth got them back.

          They basically just juiced normal ferrets to see what would happen, and they grew an extra incisor as you can see in the images posted. I’m guessing developing genetically toothless ferrets wasn’t in the scope of their funding. You can get all kinds of weird lab mice “off the shelf”, though.

            There is a lot of research and interesting things going on right now, from those latest vaccines that are amazing (and not only for vaccinating), CRISPR, longevity research etc etc etc.

            It really feels like we went from “trying out 100.000 random things to see if we can somewhat cure something” to using a more direct approach like targeted interventions and designed drugs & molecules.
