Bababoo,
"I was writing whilst you were posting the earlier one. At any rate, I am not sure what you mean by that (especially outside the context of those stored in nitrogen tanks). Please explain"
Explanation:
Human eggs are harvested at fertility clinics. They are ferilized in vitro (in a petri dish) to be implanted. As excess embryos are created for implantation, those that aren't used are stored in liquid nitrogen (-300) until they are no longer viable (alive). There are over 400,000 presently. We don't have that many "serrogate mothers" to receive them.
Would you prefer that they become "medical waste" for disposal or would you rather they be used as a source of "embronic stem cells" to expand existing cell lines and further the research that seeks cures to diseases such as Parkinsons, Alsheimers (sp), some forms of cancer, neurological damage...and many other applications.
