Summary:
Researchers announced the discovery of a more efficient way to clone mice, and said their experiment solved a basic question about cloning science — whether it truly is possible to clone animals from mature cells. However, some scientists argued that truly mature tissue is too old to be re-generated, and that Dolly and the hundreds of cloned cattle, pigs and other creatures that followed here were in fact created using stem cells or stem-like cells by accident. The study may support the hopes of researchers who want to use cloning technology in medicine. Supporters of so-called therapeutic cloning want to some day be able to take a single cell from a patient, perhaps a skin cell, and use it to generate tailor-made tissue or organ transplants.
Commentary: Maybe this discovery can be translated into an effective method for human therapeutic cell cloning and be used to develop patient-specific stem cell treatments for diseases, injuries and medical conditions.
