Okay, why don't you just stop beating around the bush and come out and say that you don't like any of this research and you think all of it should be banned out right? With this definition, you've ruled out any multiplication of any human cells at all, including adult stem cells, adult organ cells, and the cells from underneath your toenails - any experiment that involves replicating any human cells in any sort of artificial way is rendered out of bounds by your sweepingly broad definition here....
Perhaps the confusion is over when I define an individual human being as existing, and the differentiation of organ and organism. I attempted to explain that an embryo is already an individual human being, else the many tests performed prior to birth would be too generic if not done on the assumption that the organism being tested is already the oirganism to be presented at birth. The organism is being tested for anomalies. The organism that is you was already you when you implanted your life in the uterine lining of your Mother. You did that. You sent the chemical messages out that manipulated your Mother's womb environment, to accomplish your implantation. You have gone through many changes during your lifetime, but you were always you during those many changes.
Stem cells are the organs of the embryo. Toenails are tissue of the organism. A kidney is an organ within the organism. The embryo is an organism. The stem cell of an embryo is an organ of the embryonic organism.
