Researchers clone the first primates from monkey tissue cells
Kevin Sinclair
Kevin Sinclair  a developmental biologist at the University of Nottingham in Britain who was not involved with this research   said this was a significant step in nonhuman primate cloning. âIt's the first time that primates have been born using the technique of somatic cell nuclear transfer  which is the technique that was used to produce Dolly the sheep  gosh  almost 22 years ago now â  he  said.
For the clones that originated from fetal tissue  79 embryos yielded six pregnancies. Only Zhong Zhong and Hua Hua were born. âIt's still very inefficient in this species â  Sinclair  said. âThere's a lot of progress yet to be made.â
âThere is no reason to doubt that these two monkeys are anything other than clones â  Sinclair  said.
Nor   he  said  is there reason to suggest that we are closer to producing human clones today than we were yesterday. âThe techniques that these guys have used to produce these monkeys have already been used to produce cloned human embryos â  Sinclair  pointed out. No one in the field âhas ever had an agenda to produce human clones.â
 Sinclair   who has studied the health of clones such as Dolly's identical âsisterâ sheep  was bullish on the monkeys' long-term survival. In general   he  said  if clones survive the first few months of infancy  they develop like any other animal. âThe chances of them going on to lead long and normal healthy lives are very high â  he  said.
