I thought this was a huge success for science and stem cell research. I typically am a bit cautious on stuff like this, but I think stem cell technology is a GREAT thing, and that we have really only discovered the tip of the ice berg for it's capabilities. Very exciting news indeed. It disappoints me that the limitations were put on it in the beginning that were. If Obama did nothing else in his presidency, I think lifting Bush's limitations on stem cell research was a legacy worth having.

Very Cool!!! However, the Bush restrictions were on embryonic stem cells these were not embryonic stem cells. They were the patient's own hematapoetic stem cells fused with donor trachea cells, big difference since it also means he will not need to be on anti rejection meds fo the rest of his life.

Not all stem cells are created equally.

I did see that they were from bone marrow. Assuming you are opposing straight donor trachea vs stem cell+donor trachea, when you refer to lack of rejection meds and not Embryonic stem vs marrow stem cell? Neither would need Rejection meds correct?

That's great news!

Even the Pope supports stem cell research,
just not killing a human person in the embryonic stage of life in order to do it.

Scientific research and developments are a blessing.
Let's just not lose our moral bearings while we pursue them.

In this case, no one seems to have done so.
Win, win, all the way around.

Incorrect. The lack of need for rejection meds comes from the fact that the stem cells are the child's own. Embryonic stem cells are not the patients own so are subject to rejection though less so than adult transplant cells. Though embryonic stem cells are the easiest to manipulate due to their totipotent nature they still have issues. Pt. derived stem cells are much more difficult to work with but they do not have the same rejection issues. In favor of looking at both types of stem cells but I do believe there is less moral hazard involved with patient derived stem cell treatments.

Cord blood stem cells and placenta stem cells? If collected from your own birth, are those similar in compatibility to patient stem cells (ex. bone marrow)?

Yes but again those are not embryonic stem cells they are cord blood stem cells. I am unsure whether they are totipotent or pluripotent.

Your immune system is designed to protect agains all foreigne invaders even if those foreign invaders are there to save your life. The more different the invader the stronger the response that is why you can have donor matched blood but you must have a much more stringent match for organ transplant. You still have those same considerations with embryonic stem cells unless they are from an identical twin.

Cord stem cells are the best ones.
