Stem cells are versatile master cells from which a variety of tissues and organs develop.
They are considered prime prospects for effective biomedical research, and they are available from a variety of human sources, including consenting adults, umbilical cord blood and placentas. Some of the British scientists who worked on the notorious successful cloning of a sheep claimed last week, according to a newspaper called The Independent, that they can create an unlimited number of human clones, by a technique which uses an embryo s stem cells. Informed sources tell us that the time extension may be designed to encourage those who support the NIH guidelines allowing taxpayer funding of experiments using the stem cells of embryonic babies to submit their comments. Embryonic babies are killed in the process of extracting their stem cells. Embryonic babies are not things.
