"I think Singapore punches well above its weight in this area," says Colman. "That's why I'm here." Another reason is Singapore's liberal regulations, which allow stem cells to be cultured from embryos up to 14 days old, although reproductive cloning is strictly illegal.
? The Korean Cloner Hwang is down but not out Cloning pioneer Hwang Woo Suk admitted in court last week that he falsified much of his data. He could get three years in jail, a prospect that doesn't seem to daunt him; he plans to open a new lab...
Most of the errors in reprogramming, scientists say, can be traced to a process known as DNA methylation. During normal development, molecules called methyl groups attach themselves to DNA in precisely timed patterns that regulate which genes are expressed at which times. During cloning, however, those patterns are not always...
But the fact that clones have defects--however minor--only bolsters the arguments that scientists have made against human cloning. Based on his studies of the faults introduced by reprogramming, Jaenisch, for one, thinks human cloning is now out of the question. "I think we cannot make human reproductive cloning...
But Jaenisch and Wilmut both see a role for cloning in treating human diseases--and perhaps someday conquering some of man's most intractable conditions. Wilmut and others have already created cow, sheep and pig cells genetically engineered to produce a particularly beneficial human protein, then cloned those cells to...
