I always thought this was funny - like a peanut sized lung would help someone who smoked too much...

Many of the vaccines used today are derieved through exploitation of aborted fetuses. The issue of a pea sized lung is ludicrous, as you suggest. But the goal will be to remove and sustain tissues, at first, then whole organs, as therapeutic cloning moves to the fetal stage of life support before harvesting. 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.

"I always thought this was funny - like a peanut sized lung would help someone who smoked too much..." Yeah but maybe like ten of them little sacks might work. Plus you could plan ahead, (no pun intended) when you start smoking you could start a clone give it a lobodmy, feed it like cattle and chickens and after 20 years you got a new lung. you could even start a farm, with little pens for them to run around in and jump. Maybe brain transplant is the way to go, why get a new lung when you can get a new fully compatible body.
