Cloning individual human cells, however, is another matter. Biologists are already talking about harnessing for medical purposes the technique that produced the sheep called Dolly. They might, for example, obtain healthy cells from a patient with leukemia or a burn victim and then transfer the nucleus of each cell into an unfertilized egg from which the nucleus has been removed. Coddled in culture dishes, these embryonic clones--each genetically identical to the patient from which the nuclei came--would begin to divide...
...cells would not have to grow into a fetus, however. The addition of powerful growth factors could ensure that the clones develop only into specialized cells and tissue. For the leukemia patient, for example, the cloned cells could provide an infusion of fresh bone marrow, and for the burn victim, grafts of brand-new skin. Unlike cells from an unrelated donor, these cloned cells would incur no danger of rejection; patients would be spared the need to take powerful drugs to suppress the immune system. "Given its potential benefit," says Dr. Robert Winston, a fertility expert at London's Hammersmith...
When Kuo was diagnosed with chronic myelogenous leukemia in 1995, his being able to talk of the future seemed chimeric...
Gillespie said that nationally there is a total of 30,000 diagnoses of leukemia every year. But in its 12-year history, the Asian American Donor Program (AADP) has counted only 136 Asians who were able to find a compatible donor and undergo a transplant...
...advanced stage of leukemia and the fact that his donor was not a complete match, having one different antigen, lowered the odds of Kuo's recovery. After Kuo's transplant operation on Dec. 10, Kuo had a brush with death. Near Christmas, his liver and kidney functions went almost fatally askew...
