Ok, brief background in one sentence. Stem cells are generic cells that have the ability to BECOME any cell. The controversy: They are present mostly in fetus's. Science wants to use the cells from aborted fetus's to help people with problems.
The possibilities are endless. I'm talking about cures for parkinsins, lukemia, schizophrenia, spinal cord damage, stroke damage, you name it.
Scientists have already implanted stem cells in a rat that had 0% use in its back legs. After the cells generated, the right leg looked normal and the left leg was weak, but moving.
What's your take?
