After speaking with someone who is in a Stem Cell Trial for Crohn's Disease, I did a little research and it's a very exciting prospect for me to think about.  I love the idea of using my own blood cells to produce a type of cell that can reduce my disease.  For myself, I would feel more comfortable in taking something that my body already produces versus a biological with a million and one terrible side effects.  However, it is not without risks as I am reading and without warnings, some to me seem severe.  I am still interested in more information and I am going to keep my eyes peeled for a Trial that I can join, maybe there is hope yet.
