Liposuction Leftovers Are a Stem Cell Bonanza

The movie Fight Club may have been on the right track when it suggested that the fat left over from liposuction procedures was too valuable to throw away--although the idea of making soap from forsaken flab is too gross to catch on. Instead, researchers have found a way to turn fat cells into stem cells, and say the process is much more efficient than the standard technique for stem cell production, which uses human skin cells.
