This Isn't Science Fiction Anymore


Sometime an event occurs which makes it actually look like I might know what I am talking about.....

This past week in my human genetics class, we discussed the possibility of turning back the clock on adult stem cells to make them behave like embryonic stem cells. The lure of embryonic (or ES cells) is that they have not yet realized their genetic destiny, and therefore have the potential to become any stem cell. Of course, the main problem has been where ES cells were obtained from - most cells come from left-over in vitro fertilization (IVF) events, and some people have expressed a concern over the ethical use of these cells.

In the December 10th edition of Science (vol 322, issue 5099), the editors of the journal awarded the 2008 Breakthrough of the Year to the process that generates an induced pluripotent stem cell, or iPS. iPS cells are adult stem cells that have been genetically altered to behave like ES cells - opening up the possibility that they may be developed as a alternative source of stem cells. Furthermore, research in this area has suggested that it may be possible to develop iPS cells as a form of treatment for a wide variety of diseases, including Down Syndrome, Huntington disease, and juvenile diabetes. Anyone who has an interest in stem cells, and the future of medicine, should definitely read this article. Sometimes the facts are more interesting than the fiction!
