Good question. If you lay out your options that you know about, I'll point out if there are among them any acceptable ones in my opinion.
Based on your username are you Jewish?
Because you'll be interested to know that Judaism not only permits embryonic stem cell research it actually encourages using the embryos rather than wasting them.
Nope, not Jewish. Only by stem cell. Religions are insufficient in some major ways. But they found time to include a clause about embryonic research, huh?
Are you looking for an answer or do you just want to be snarky?
I gave you what you need to know to answer your question... I don't care what a religion says. They usually don't know what they're talking about. I didn't know any religion validated embryonic stem cell harvesting and I am saying that completely honestly.
