The group of researchers at Children's (Hospital Boston) is one of only five academic teams in the world with plans to clone human cells, a highly controversial technique. Yet, unlike the other groups, which hope for medical applications down the road, but are geared toward basic science, the team at Children's is focused on making cells to cure patients. Being at this hospital, where doctors sometimes watch helplessly as a young life slips away, makes them feel they do not have a day to waste. "It can be very emotional," said Dr. Leonard Zon, director of a new stem cell program at Children's. "There is a sense of urgency." In pursuit of this goal, Zon and his colleague, Dr. George Daley, have been drawn deeply into an area of science that is looking for a precise answer to a seemingly simple question: where does blood come from?
Blood is so complex that scientists refer to it as an organ, like the brain or the heart. It includes the red blood cells that carry oxygen, at least five main types of white blood cells that protect the body, doing battle with invaders, as well as other specialized cells. Many things can go wrong with this system, such as leukemia, when blood cells become cancerous, or a long list of genetic diseases, including anemia, where the red blood cells do not form properly. To do bone marrow transplants today, doctors first use a combination of drugs and radiation to kill a patient's blood system. Then they give the patient bone marrow from a donor---often a family member---whose marrow is similar, and unlikely to be rejected by the body. In this bone marrow are a small number of blood stem cells. After they are injected into the patient, these stem cells travel to the patient's bone marrow, take up residence, and then completely rebuild the entire blood and immune systems. These blood stem cells, like every other cell in the body, began as a single fertilized egg cell. Using mice and tiny fish, scientists at Children's and elsewhere have been discovering how cells specialize as an embryo develops and trying to imitate that specialization in the laboratory. While these experiments are under way, the work on cloning human cells has not begun because the team does not yet have permission from the participating institutions, or from an independent board, which by U.S. federal law, reviews all research that involves people.
