Hair
In an experiment that holds out hope for remedying baldness, a team from Durham University in the U.K. succeeded recently in getting the hair of researcher Dr. Colin Jahoda to grow on the inner arm of his wife, Dr. Amanda Reynolds. As reported in Nature (11/4/99), cells from Jahoda's hair follicles were transplanted without rejection into Reynolds' skin, whose own cells triggered the hair growth following instructions from the transplanted cells.
