Stem Cells Tailored to Patients

I myself have been a supporter of stem cell research. I'll admit it's kind of creepy, but who am I to say that someone should suffer or die? Recently a group of Korean Scientists made a huge advance, they created stem cells that immunologically compatible to the donar. This means what? They have produced cells that won't be rejected by the body in treatment. This means what? They can synthetically produce cells that can treat ailments and inject them into the body and they won't be rejected. It's not good to go yet, traces of the diseases which would be treated by this method still exist in the stem cells, but either way the potential is enormous. Imagine cancer cures, that's pretty profound.

Some people say, ahh you're killing live. There are no babies in the embryos they are using, so it's not life to me, and clearly if these embryos were donated they weren't going to become babies anyway. My opinion isn't really the point though, I just thought this held quite some weight.
