Clones.(FROM READERS)(Letter to the editor)
The article "Food from Cloned Animals Receives Preliminary Approval" (March/April 2007, p. 8), gave me a great shock, since in Japan this kind of opinion perhaps has gone out of the discussion about food and the food market, though I am not sure. As one of the animal scientists who participated in research on genetic engineering by using chicken and cattle at the university in this country, I would like to say something about this news item, though five years have passed since my retirement from the college.
The technique for cloning is not so easy, and you may only be able to get a few successful results from animal cloning. In my students' case, 1 out of 600 to 700 treated chicken eggs (equal to chance mutation) was successful. Though I am not sure about recent advanced techniques for animal cloning, especially for cattle, pigs, or some other farm animals, even now it may take a lot of time to produce cloned animals with highly sophisticated methods.
In my laboratory at the university, we also found various interesting things about the genetically engineered chickens, such as short lifetimes, no breeding ability, and deformed legs that prevented normal walking, despite the fact that some of the exogenous genes were completely introduced into the host embryos.
As a result, I think, if something like mutation had occurred in the process of genetic engineering, these genes could be transferred into the next generation, but further generations might have some different characteristics owing to slightly changed altered genes which occurred in the process of genetic transmission.
In addition, the genetically modified birds also had a few different unknown characteristics in the body, but these features were completely excluded gradually during their living time, though the lifespan was not so long compared with normal birds. This also means that the extra or foreign genes may not be stored in the living cells for long, due probably to the reason that inherent genetic materials couldn't be replaced with ease by ...
