nes, and they can figure out how they work, then a cure for cancer is possible. Not all stem cells come from embryos. So anti-stem cell researchers have proposed the idea of researching on adults, since adults also have stem cells in their bodies. But they are few in number, hard to locate, and do not represent all the types of tissue in the human body. Also, environmental conditions might have changed the condition of the adult stem cells over that persons life. So you might say that adult stem cells could be corrupted.Another method of obtaining stem cells is SCNT, or somatic cell nuclear transfer. In this process, a hollowed-out human egg is placed by a somatic cell of any type. These two cells are now fused together. The resulting cell is theoretically totipotent and can be used to obtain stem cells from.I believe that stem cell research should continue, full-fledged, but with limitations. As long as the embryos are extra embryos left over after In Vitro fertilization in fertility clinics and not embryos produced just for research. Also the embryos must be taken with the consent of the couple. These embryos are extra, and will usually not be needed anymore. Also, they result in huge custody cases if the couple divorces. Why should these embryos be left in a freezer and result in civil suits when they could be helping mankind? I also believe that if the embryos develop into a fetus, stem cell extraction should stop. For me, the limit for research is the blastocyst....
