"Many of the tissues in your body produce endocrine chemicals necessary to 'cure', reverse, or alleviate ailments, such as diabetes. It would be possible to treat Parkinson's disease with the brain tissue from a clone of you not already suffering parkinsonian symptoms."

You seem to know what you are talking about, but are endocrine chemicals presently rejected because of DNA differences ?
You say "It would be possible to treat ... " you don't say anything about if this type of treatment would have any possibility of success.
- again, is brain tissue presently rejected because of DNA problems and have experiments shown that the procedure you are expecting to be performed would be successfull if the DNA matched ?

Sorry, I missed your #11.

Tissue rejection usually is caused by the body's imune system attacking the foreign tissue because of the 'proteins' mismatch. With a clone, the idea is to duplicate the proteins of your body, in the clone, thus the tissues of the clone will not be recognized as foreign when implanted. Some bone transpalnts are now accomplished without the anti-rejection drugs so heavily used with typical ransplant therapy. The technique involves freezing the bone to a very low temp before thawing and transplanting. Again, hocndoc can give you much better information here.

as an aside, we treated my son with growth hormone derived from cadaver pituitaries (back in the 70's; no synthetics then). The hormone was not rejected because only the molecules were injected, leaving the proteins in a lab centifuge.
