Japan grows tooth from stem cells

According to a report in the journal Public Library of Science One, Japanese scientists have grown a tooth from stem cells that was implanted into the kidney of a mouse. The tooth is not functionally normally.
The Japanese team grew the tooth, within a drop of collagen, from stem cells within the kidney of a mouse.
The fully developed tooth was then transplanted into the lower jaw of another mouse. The transplant, after forty days within the young mouse, appears to be functioning normally.
Supposedly, this is the first time that such a procedure has been performed.
Dr. Takashi Tsuji, a researcher at the Tokyo University of Science, was one of the members of the team.
Tsuji stated, "At present, researchers worldwide do not have the method to culture three-dimensional organs in vitro (outside the body)." [Reuters: 'Experts grow whole tooth units using mouse stem cells']
And, "It is important to develop technologies for the culture of the bioengineered organ ... for the realization of future organ replacement regenerative therapy."
