Excuse the bio-ignorance but what is the basic game plan for getting the stem cell to grow a particular organ? How do you trick it into growing a lung (for example), and how do you keep it alive while it's growing? Is there any way to speed up the growing of the lung so it doesn't take 15 years to reach adult size?
