Researchers say they have confirmed suspicions that embryonic stem cells claimed to be extracted from the first cloned human embryo by discredited South Korean scientist Woo Suk Hwang actually owe their existence to parthenogenesis, a process in which egg cells give rise to embryos without being fertilized by sperm. A series of genetic markers sprinkled throughout the cells' chromosomes show the same pattern found in parthenogenetic mice as opposed to cloned mice, according to a report published online today in the journal Cell Stem Cell. The result suggests that, although Hwang deceived the world about achieving the first human cloning, his group was first to succeed in performing human parthenogenesis, which may offer a way of creating cells that are genetically matched to a woman for transplantation back into her body to treat degenerative diseases. "I think this is an extremely important-and solid-paper," says stem cell researcher Robert Lanza, vice president of research and scientific development at Applied Cell Technology, a regenerative medicine company headquartered in Alameda, Calif., who did not take part in the study. "It conclusively proves that the stem cell line in question was not cloned as claimed, but rather was generated through parthenogenesis." The result follows on the heels of an announcement last month by another California stem cell company, International Stem Cell Corporation (ISC) in Oceanside, that it had successfully achieved human parthenogenesis for the first time. Last year, Italian researchers claimed to have achieved the same feat but have yet to publish their results. "The fact that this has now been achieved by two independent groups gives me a far greater degree of confidence," Lanza says. The new finding brings a measure of closure to a story that first rocked the science world in February 2004, when Hwang and colleagues at Seoul National University announced they had cloned a female donor's cell by transferring its nucleus into one of her egg cells stripped of its nucleus in a procedure known as somatic cell nuclear transfer (SCNT), and harvested embryonic stem cells from the resulting fusion. They published the result the next month in Science. FIRST (DELIBERATE) HUMAN PARTHENOTE: In late June, a California company published the first report of cells derived from human eggs stimulated to grow into embryos.
