A linkurl:report;http://stemcells.alphamedpress.org/cgi/reprint/2007-0252v1.pdf published online today that researchers have cloned human embryos is not that much of an advance, according to one stem cell expert, Douglas Melton, at Harvard University. (the-scientist.com)
Several of the reconstructed oocytes developed as normal embryos, although only one of the blastocysts contained donor DNA or mitochondrial DNA. (the-scientist.com)
Moreover, most early-stage embryos that are produced naturally (that is, through the union of egg and sperm resulting from sexual intercourse) fail to implant and are therefore wasted or destroyed. (wikiquote.org)
