Cloning cell lines

Several theories have been suggested as to why the vast majority of cloning attempts end in failure. One study discovered that only a small percentage (34%) of cloned mouse embryos correctly express a gene called Oct4 that is vital for normal development. Further tests showed that the small number of cloned embryos that went on to develop to a stage where they produced stem cells all expressed Oct4 in the right places and in the right amounts.
