I do not know about you, but I`m bit disagree with the development of cloning technology even if it is for an animal, because I am sure that one day they will do it in humans too!!!
Well, recently scientists from Riken Bioresource Center in Japan has successfully to clone a mouse only by using blood cells collected from other mouse. Interestingly, this genetically engineered mouse can still live a normal life.
The white blood cells are injected into DNA egg cell. After that, the nucleus of white blood cells will turn into an early stage embryo.
Through this success, Japanese scientists has showed that for the first time a mouse can be cloned using the nucleus of leukocytes.
