It makes so much sense to be able to use your own stem cells to heal your body. After all wouldn’t the use of another person/embryo’s stem cells require the life time use of rejection medications because of the use of a different dna? While use of your very own stem cells wouldn’t? This is a question I’ve wondered about. Anyone have the answer?

I am certain that you are correct. I posed your question to a couple of faithful NPR listeners some time back and got a confused look. Evidently NPR had not told them what to think about it yet. Then they came back with “that problem will be solved”.

It’s not the different DNA that causes rejection problems. Rejection is caused because the implanted cells have a different set of antigens (surface proteins) than the host cells. The host immune system recognizes those foreign antigens as invaders and attempts to destroy them.

Autologous stem cells (that is, made from the patient’s own body) will have the same antigens as the rest of the body, and will not trigger the rejection reactions.

I will be glad to explain further or answer any other questions.

As a general rule, if you don’t have perfect matches in any kind of transplantation, you’ll get either graft versus host disease or host versus graft disease if you don’t use immunosuppressant drugs.

Unless they can prove otherwise, any kind of human embryonic stem cell source for transplanting will need immunosuppressants.
