Better vote Democrat then. I agree with you 100%.

I recall reading about some new research that allows for stem cells to be produced without involving any embryonic anythings. Might anyone happen to remember that, or have any relevant links?

With a breakthrough like that, I don't see why the opposition to traditional embryonic stem cell research could possibly remain opposed.

No one opposes stem cell research (except some fringe people who want nothing to do with biotechnology). The moral problem comes when you have to destroy embryos to obtain the required cells. However, it's not really an issue as the most successful experiments have come from use of adult stem cells or embryonic cord cells. Thus the whole "not funding stem cell research" is a misnomer: it's EMBRYONIC stem cell research.

Also, marrow transplants are not such a new thing; they're fairly easy to do as well. My friend from high school has brain cancer; they took some of his blood and stored it while giving him superdoses of chemotherapy that totally destroyed his immune system (bone marrow stem cells that produce white blood cells and whatnot). Then they put his stored blood back in and it automatically reseeds itself in his marrow to reboot his immune system. Stem cells; no embryos killed; profit!

There is always a profit to be made off of killing embroys.

One thing I don't understand here.....

If you're getting a new organ, which ever it might be, doesn't the donor have to have the same blood type as you in the first place?

I have a coworker who got a bone marrow transplant from his brother while fighting leukemia.

Now if you were to do a DNA test of the two, they would be the same.

seriously? I thought even though some things can change, I thought the DNA would remain the same, because other details of your body are still going to be unique.... ??

Bone marrow is where your blood cells are created right? Is it possible to contains two sets of DNA? Blood containing one set, and other parts (skin, hair) containing another?

edit: Come to think of it...did I see something like that in a Law and Order once?

it's called Chimera. learned about it in biology.

Unbelievable.

You don't need to be the same blood type to receive and organ, you just have to be histocompatible. That involves unique cell-surface receptors on the organ rather than on blood cells. Family tend to have similar receptors, while an identical twin will be the same. There isn't much blood in the organ when it is implanted, just some solution to preserve it.

That's awesome.

Is this a question or answer?
