Well, it’s just a tooth, but a tooth is actually a complex organ and it is an exciting first for scientists to have implanted a tooth made from stem cells into a mouse, where it integrated, survived and functioned pretty much as a normal tooth.
As the authors say: “This study serves as a proof of concept that complete organs can be grown from harvested stem cells and, when transplanted, achieve normal function, hopefully advancing the field from stem cell transplantation for organ repair towards full organ replacement.”
