Regrowing Teeth and Hair with Stem Cells

I read that they are able to grow certain body parts such as teeth using stem cells, cant they find some type of cell attached to the regrowth of hair? just wondering

I am afraid it is not so simple as you present it. The theory is good (stem cells will be a source of new hair), but that is simplistic. The problem of trying to grow hair from stem cells has defeated many researchers who see billions of dollars in successfully cloning hair from stem cells. The chapter of that book has not be written yet.

In a verbal presentation at the ISHRS conference a few years back, a few patients who had stem cells transplants taken from hair growth centers in experimental circumstances not only grew a few hairs from the stem cell transplants, but parts of bone and muscle also appeared. I don’t know about teeth. Clearly, our ability to take control stem cell growth is limited.
