A 2021 study out of Japan showed how targeting genes can regrow teeth in animals. Now, the team has turned to a human clinical trial.
By targeting the USAG-1 gene, researchers believe that they can help people without a full set of teeth regrow teeth.
The team says that humans have a third set of teeth available as buds, ready to grow as needed.
A sliver of what makes sharks so intriguing comes with their ability to regrow teeth. And while a group of Japanese researchers aren’t claiming that we should be trying to be the most shark-like possible, they’d like for us to maybe, someday, share that same ability.
