"Is More Better?
In the case of stem cells, the answer is yes, assuming that more stem cells still means viable, high quality ones. Embryonic stem cells are capable of almost unlimited division, or proliferation, when placed in a culture whereas adult stem cells do not multiply so readily. The difficulty level varies as well; embryonic stem cells can be grown fairly easily in the laboratory whereas adult stem cells are not easily grown after isolation from mature adult tissues. Stem cell replacement therapies require large numbers of cells and the current difficulty in growing large numbers of adult cells means that their use for therapy at present is limited." http://www.explorestemcells.co.uk/adultvsembryonicstemcells.html
For my argument I personally focus on two main things: 1) embryonic stem cell are NOT children and 2) canNOT do everything that embryonic can do
I am very religious and don't like the idea of killing what could be a child, however, that's not what embryonic stem cells are. Embryonic stem cells don't have a heart beat and are therefore not human beings yet. Many people can agree with that but then they make the point about having thought and feelings and a soul and when doesn't that happen?...It doesn't in embryonic stem cells because the embryonic stem cells have no nervous system and can't feel anything.
People think that adult stem cells can do everything embryonic stem cells can and are therefore the easy answer...but they are simply wrong. Embryonic stem cells can become any lost or damaged cells and will not reject because they have not been "copywrited" yet.
I believe that scientifically it is not what most people think and that once you start to understand what they really are it becomes clear that socially and morally this would be the bet route that.
