It's not gene mutation, it's gene expression," he says. "This is not something you can set up a test to prevent." Ryuzo Yanagimachi, a professor of anatomy and reproductive biology at the University of Hawaii and co-author of the study appearing in this week's issue of Science, says "it is outrageous and irresponsible to try human cloning." The work also casts some uncertainty on the field of stem cell research for fighting disease. In this field, scientists propose using embryonic stem cells to clone adult human cells and tissue, which then can replace diseased tissue of those suffering from heart disease, multiple sclerosis, Alzheimer's and other diseases.In a press release from Yanagimachi's office, caution is directed toward stem cell researchers, saying the study "is a warning to scientists that they must be very cautious in handling embryonic stem cells" which "may not be normal in a physiological or functional sense."
