The science tells us that at least one individual human being starts a lifetime to be lived, at the conception event. With cell division, it is apparent to science that at least one individual human being is expressing their ORGANISMAL life, even to the exquisite level of starting the division of cells to build his or her own placental 'space capsule' for the water world to be lived in for nine months and the blood to be circulated through his or her own constructed umbilicus. The living 'thing' doing this designation of cell lines is called an embryo, but this is indeed the same human ORGANISM who will exit the life support protection of his or her Mother in nine months time, to then live in the air world. All during that nine months, it is the same individual or individuals (in the case of twinning) who first manifested as embryonic human(s). Why would you divorce moral principles from the treatment of these youngest individuals when you would willingly apply moral principles to older individual humans?... Or would you?! I will not concede to allow some to divorce moral principles from scientific endeavors. I find it shocking that you advocating doing that, but then I do recall that there are persons in all walks of life who profess themselves to be a-moral, above fundamental moral principles, wise enough to deal with any situation from a transactional/utilitarian perspective setting moral principles aside to be defined incident by incident.
Not cannibalism? Not eating the embryos for their stem cell body parts, so this is not cannibalism? Well, to harvest the stem cells of these individual human ORGANISMS in order to try and sustain the life of older individual humans fits my understanding of cannibalism and would likley fit with the vast majority of my fellow Americans, so I'll continue to use the term with the confidence that it accurately describes the actions planned with alive embryonic human individuals.

Not that many people are both as zealous as yourself and as hyperbolic at the same time. Most people, when thinking of cannibals, think of tribes of savages in jungles or of Jeffery Dahmer types. It really is not a term which comes to mind when considering researchers attempting to cure disease. However, I guess some get enjoyment out of misusing words, and then patting themselves on the back for their cleverness. I bet you call abortion doctors "serial killers" too, right?
