Summary:
In a scientific first, University of Pittsburgh researchers announced they have cloned two live mouse pups from a mature white blood cell. Mature cells -- called fully differentiated cells -- are incapable of dividing or turning into other types of cells, as stem cells can. However, independent experts questioned the validity of the experiment, arguing that animals already have been cloned from mature cells -- and in a more convincing fashion.
Commentary: It seems as though this experiment will need to be replicated in order to be proven valid, and it remains to be seen whether this new cloning technique will have effective human therapeutic benefits for diseases and medical conditions in human patients.
