Fully Functional Bioengineered Tooth Grown In a Mouse

A couple of weeks back the Wall Street Journal reported on the first organ grown in vivo from stem cells — a tooth in the mouth of a mouse. Reader cdrpsab spotted the news on the MedGadget blog; the research had been reported earlier in the PNAS. From the WSJ: "The researchers at the Tokyo University of Science created a set of cells that contained genetic instructions to build a tooth, and then implanted this 'tooth germ' into the mouse's empty tooth socket. The tooth grew out of the socket and through the gums, as a natural tooth would. Once the engineered tooth matured, after 11 weeks, it had a similar shape, hardness and response to pain or stress as a natural tooth, and worked equally well for chewing. The researchers suggested that using similar techniques in humans could restore function to patients with organ failure."

    The submitter got me, I have to admit. I was reading the summary, thinking that it would end with "could allow humans to regrow teeth"... but they pulled a zigzag, and went a different direction. Organs. Wow. Did M. Knight Shamalyan write this summary?

      The problem with growing organs is that in order to get cells to multiply you have to disable certain genes in those cells, or at least reset their counters ....

      I don't know about anyone else's family, but a quarter hasn't been good enough in my family since I was a kid in the 1980s. These days, the usual price for one tooth is $2. The tooth fairy usually gives it in the form of a $2 bill, depending on whether or not she had time to go to the bank and get a $2 bill before the tooth fell out.
