Shane - the intent of this thread isn't to argue pro-life vs pro-choice, but I did want to inform you once again that embryonic stem cells can be taken from those that you say "become" human once the umbilical cord is clamped off. My argument being that these "humans" will continue to "become humans" (per your argument) and thus these stem cells will be wasted. We aren't going to stop having "humans". Why postulate when we "become" human or whether or not life begins at conception when really, these are up to individual belief. Stem cells from cord blood do not threaten anyone's beliefs unless considering someone who is against western medicine entirely.
A few more points...an embryo vs a fetus is a faulty point to even mention. A fetus doesn't magically turn into something else on the first day of the eighth week...it's merely larger than it was the day before. It's silly to defend one's position on such logic. Just because a fetus is born (thereby becoming "human" per your argument) doesn't make that child self sufficient, as you suggested it does. An infant can be left alone after birth and that child will die without care - hardly self sufficient. It has to be cared for whether inside the womb or outside of the womb. Perhaps the science just won't be correct or we shouldn't consider an infant "human" until we're able to create them with a fork in their hand and the ability to walk and talk? I appreciate your argument...but it's important to note that we don't even have to debate this issue with the consideration of cord blood stem cells.
The following excerpt discusses cord blood stem cells and CF....
"The latest research in Australia, Germany and the United States shows that stem cells from cord blood can give cells that are very similar to lung cells. In a mouse model for cystic fibrosis, the cells help to cure the disease. And here in Melbourne, at The Alfred Hospital, it has been shown that when lungs are transplanted into patients, they appear to take up stem cells from the recipient and integrate them into the airways."
