Summary:
By cloning two mice from cells adult blood cells incapable of dividing, researchers have defied the notion that cloning mammals is easiest from stem cells, or other cells that are still dividing. Researchers believe the result might be of interest to researchers who hope, in future, to clone a patient's cells and use the resulting embryo to extract human embryonic stem cells and treat disease. The results show that it might be possible to obtain a patient's nucleus from the cells in a simple blood sample, rather than having to use special stem cells.
Commentary: Maybe this finding will be a scientifically viable alternative to embryonic stem cells, yield effective treatments for diseases in humans, and end the ethical controversy that has surrounded the field of embryonic stem cell research.
