Lab successfully clones human embryos
La Jolla, Calif. (UPI) Jan 17, 2008 A U.S. laboratory said it is the first to create and document a cloned human embryo using somatic cell nuclear transfer. Stemagen, a private research lab in La Jolla, Calif., said five blastocysts were developed from 25 donated mature oocytes. Three were confirmed to be clones based on DNA fingerprinting demonstrating the presence of the skin cell donor DNA in the blastocyst, while one was further confirmed to be a clone by an additional mitochondrial DNA (mtDNA) analysis which revealed the presence of oocyte donor mtDNA without any oocyte donor nuclear DNA. Cloned blastocysts were successfully created from approximately 10 percent of all mature donated oocytes, an unexpectedly high rate given past research in this field, the company said Thursday in a release. The research was published in the journal Stem Cells. Stemagen CEO Dr. Samuel H. Wood, donor of the cells from which the embryos were cloned, called the achievement "a critical milestone in the development of patient-specific embryonic stem cells for human therapeutic use, potentially including developing treatments for Parkinson's, Alzheimer's and other degenerative diseases."

UN Analysis Lays Out Global Choices On Cloning For Human Species
New York NY (SPX) Nov 12, 2007The world community quickly needs to reach a compromise that outlaws reproductive cloning or prepare to protect the rights of cloned individuals from potential abuse, prejudice and discrimination, according to authors of a new policy analysis by the United Nations University's Institute of Advanced Studies. |
