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. Following up on a 2021 study (published in Scientific Reports) that showed how medicine targeting the protein synthesized by the USAG-1 gene could impact the number of teeth grown in animals, the team has turned its attention to humans. They’ve announced a 2024 clinical trial of the medicine, which...…Skip to ContentWhy Trust Us?A sliver of what makes sharks so intriguing comes with their ability to regrow teeth.
