According to the President's Bioethics Council,
http://www.bioethics.gov/
the results of somatic cell nuclear transfer, or cloning, are "cloned human embryos." Parthenogenesis would be no different, in my opinion. The embryos develop into blastocysts, and on through development.

As to the "potential" of a being defining that being: poor logic. The embryo is genetically human and alive or it's not. Any discrimination between whether it's human enough to experiment on and kill is not scientific - it's a personal bias.

"The embryo is genetically human and alive or it's not. "

... and since YOUR definition of alive appears to be that of an egg that now has the potential to divide ( vs. an egg that does not ) your circular logic works well.

An embryo is human and it is alive, but it isn't a human being.

let me ask you this question.
if it was possible, and someone took cells from your liver and they just began differentiating into a new liver, would you call it an organ or potential organ?
