In reply to GregCHF:
I would like to avoid derailing the thread, so just the one post: Never mind GM, a quick google will show you hundreds of sites like this one
http://www.startstemcells.com/diabetes-type1-treatment.html
that offer experimental (at best) or obviously nonviable stem cell therapies to desperate patients with life threatening diseases. Some treatments on offer correspond to approaches that are still at the level of basic basic research and may eventually go into clinical translation, while other suggested treatments clearly cannot work in principle (e.g. the transplantation of autologous stem cells from fat tissue in type 1 diabetes patients: Even if they magically were to become beta cells, they would be destroyed like the original ones!).
These web sites also exploit the gullibility of people, but in a criminal rather than funny way. Exploiting dying people in this way is probably one of the lowest levels you can sink to.
