Stem cells tailored to patients
South Korean scientists say they have made stem cells tailored to match the individual for the first time.
Each of the 11 new stem cell lines that they made were created by taking genetic material from the patient and putting it into a donated egg.
The resultant cells were a perfect match for the individual and could mean treatments for diseases like diabetes without problems of rejection.
The study, published in Science, has been hailed as a major advance.
