It seems that ever since stem cells have been used for the benefit of human health, they've been followed by controversy the whole way, mostly as a result of where they are harvested from. Well, now scientists have found a promising new source of stem cells in a place that nobody had likely imagined: liposuction leftovers!
As gross as this might sound, the discarded fat removed from flabby areas is actually a really good source of immature fat cells, which can easily be transformed into 'induced pluripotent stem cells' (or iPS for short). These immature fat cells are reportedly easier to work with than other types of cells used to make iPS cells for research, and they can be used to create heart, bone and brain cells (just to name a few) which have the potential to be used to treat disease.
To catch up on all the details, check out the article called "Liposuction leftovers make easy stem cells: study" at Reuters (Sept. 8, 2009)
