Embryonic stem cells can differentiate into the three "germ layers": [[ectoderm]], [[endoderm]] and [[mesoderm]].  The 220 types of cells in humans are all based on these germ layers.  Some scientists have shown effectively that embryonic stem cells have greater differentiation potential, and divide into greater numbers, than [[adult stem cells]] can.

[[Pro-life]] conservatives consider taking stem cells from human embryos, as tantamount to [[abortion]], which they believe to be a hideous and [[evil]] practice. President Bush was pressured by [[Scientist]]s into funding stem cell research[http://www.whitehouse.gov/news/releases/2001/08/20010809-2.html].

[[Pro-life]] conservatives consider taking stem cells from human embryos as tantamount to [[abortion]], which they believe to be a hideous and [[evil]] practice. In actual fact, embryos used for stem cell research are already condemned to death because most of them are the byproduct of [[In Vitro Fertilization]] procedures which generate many more embryos than are needed to implant in the woman.  With no further use for these embryos, they are often destroyed. Embryonic stem cell research does not result in the destruction of any additional embryos. <ref>http://humrep.oxfordjournals.org/cgi/content/full/18/4/672</ref>
