Controversy surrounding stem cell research
Main article: Stem cell controversy
There exists a widespread controversy over stem cell research that emanates from the techniques used in the creation and usage of stem cells. Embryonic stem cell research is particularly controversial because, with the present state of technology, starting a stem cell line requires the destruction of a human embryo and/or therapeutic cloning. Opponents of the research argue that this practice is a slippery slope to reproductive cloning and tantamount to the instrumentalization of a human being. Contrarily, some medical researchers in the field argue that it is necessary to pursue embryonic stem cell research because the resultant technologies are expected to have significant medical potential, and that the embryos used for research are only those meant for destruction anyway (as a product of invitro fertilisation). This in turn, conflicts with opponents in the pro-life (anti-abortion) movement, who argue that an embryo is a human being and therefore entitled to dignity even if legally slated for destruction. The ensuing debate has prompted authorities around the world to seek regulatory frameworks and highlighted the fact that stem cell research represents a social and ethical challenge

How I understand this they take an Embroy and start from it to form stem cells... I do not agree with abortion... I will have to study this... I am uncertain.. but I do believe that life begins at conception. Questions that we would ahve to ask is: How would it affect us in the future.. ect;
