I heard an extraordinary explaination Ron Reagan Jr. made in a speech on the subject...
"...Now, imagine going to a doctor who, instead of prescribing drugs, takes a few
skin cells from your arm. The nucleus of one of your
cells is placed into a
donor egg whose own nucleus has been removed. A bit of chemical or electrical stimulation will encourage
your cell's nucleus to begin dividing, creating new
cells which will then be placed into a tissue culture. Those
cells will generate 'embryonic' stem
cells containing only your DNA, thereby eliminating the risk of tissue rejection. These stem
cells are then driven to become the very neural cells that are defective in Parkinson's patients. And finally, those cells -- with your DNA -- are injected into your brain where they will replace the faulty cells whose failure to produce adequate dopamine led to the Parkinson's disease in the first place.
In other words, you're cured. And another thing, these embryonic stem cells, they could continue to replicate indefinitely and, theoretically, can be induced to recreate virtually any tissue in your body. How'd you like to have your own personal biological repair kit standing by at the hospital?...By the way,
no fetal tissue is involved in this process.
No fetuses are created, none destroyed. This all happens in the laboratory at the
cellular level..."
We are talking about an unfertilized egg, not an embryo; that is misleading. I wish it was called cellular stem cell research, since that is what it is.
