The findings, published in a new study in the journal Nature Communications, suggest there’s a hard limit to duplicating mammals. And to scientists hoping for “infinite” cloning, this came as a major let down.
“We had believed that we could create an infinite number of clones. That is why these results are so disappointing,” study senior author Teruhiko Wakayama, of the University of Yamanashi, told Reuters.
“At this point, we have no ideas for overcoming this limitation. I believe we need to develop a new method that fundamentally improves nuclear transfer technology,” he added, referring to leading technique for animal cloning.
