Down side of stem cells I hear is it can easily transform to cancer cells.
One of the things to overcome for this method to become mainstream I am guessing.
Hmmmm?! Stem cells can become whatever cells they want to. That's why they are called "stem" cells. Every type of tissue naturally contain high levels of stem cells, ready to differentiate into any kind of cells they need to be. In fact, ALL stem cells used in research have been isolated from patient volunteers.
Getting oncogenic mutations in stem cells has the exactly same probability as any other kind of cells. No more, no less.
Understanding what makes stem cells transform into the kind of tissue cells they are destined is absolutely crucial to understanding of any kind diseases.
Stem cell IS mainstream. No doubt about it. Stem cell research is getting along full steam ahead on every aspect imaginable. The only issue associated with stem cell work HAD been the use of embryonic stem cells. That's mainly an ethical issue, not scientific. We don't use embryonic stem cells now. We now use adult stem cells, which are donated by patients just like how people donate blood, with full compliance.
