New stem cell isolation protocol

AI Thread Summary
Recent advancements in stem cell research have led to a technique that allows for the establishment of human embryonic stem cell colonies from early embryos without destruction, potentially alleviating the primary ethical concerns surrounding this research. This breakthrough, if validated by further studies, could shift the political landscape regarding stem cell debates, particularly among religious conservatives who equate embryo destruction with murder. Dr. Robert Lanza, a leading figure in the research, asserts that there is now no rational basis to oppose such studies. However, skepticism remains about whether this development will significantly influence political discussions, as some believe that objections are rooted in deeper ideological beliefs rather than scientific rationale. Additionally, a light-hearted exchange occurred regarding the number of ova in women, clarifying that while women are born with approximately 1-2 million follicles, only about 400 mature into ova throughout their reproductive years.

Stem Cell News Could Intensify Political Debate

Biologists have developed a technique for establishing colonies of human embryonic stem cells from an early human embryo without destroying it. This method, if confirmed in other laboratories, would seem to remove the principal objection to the research.

Good news but I am afraid it will not help the political debate

That is indeed good news. The objection seemed to stem from the principle that since you could not know when life began, that killing an embryo could be equated to "murder" has been neatly sidestepped by this. Are you suggesting though that this is not enough to ease the concerns of the religous conservatives?

“There is no rational reason left to oppose this research,” Dr. Robert Lanza, vice president of Advanced Cell Technology and leader of the research team.

In my opinion there was no rational reason to oppose this research in the first place whether the Embryo died or not. But then I'm not a Christian, although I respect their right to object if not their reasoning.

As a matter of interest just how many embryos are there in a healthy woman?

None. Unless she is also pregnant.
 
My bad, I mean how many ova are there in a woman. Thanks for the clarification, I was on serious mind altering drugs when I wrote that :wink: :smile:

Oh, that's different :smile: :wink:
AFAIK somewhere around 1 or 2 million folicles at birth. Perhaps 400 or so mature to be ova.
