This might be possible to make work for adults in addition to embryos due to the fact that Multipotent Adult Progenitor Cells (MAPC's) are showing themselves to be possibly equivalent to stem cells of embryonic origin in many other stem cell applications. To give you an idea as to just how much potential these MAPC's appear to have consider the following. A chimeric mouse embryo was created by fusing several adult mouse derived MAPC's with an ordinary mouse embryo at the blastocyst stage. The chimeric mouse was found at birth to have MAPC derived cells of every tissue type composing a significant portion of it's mass. The MAPC cells were apparently able to differentiate into every cell type just as effectively as the original ES cells. The experiment has now been repeated successfully several times. It would seem that given the correct micro-environment it is possible to culture any and every cell type using only cells derived from an adult. Already the conditions needed to coax these MAPC's into a few dozen tissue types have been discovered.

an interesting thread. i'll comment, that i also DO think that choice can possibly factor into sexuality, but that the large majority of the time, it does not.
This goes along with my other theory, that most (if not all) people are really bisexual, and most just havn't realized it; due to a variety of factors, mostly sociological.
i can't really back that up with anything more than my own personal observations, but nonetheless, i think it's true, and i just wanted to voice my opinion 
for a good book that raises interesting questions on sexuality, check out The Braided World my apologies for not remembering the author at the moment.
