program's research includes several free and open-source software projects. Stem cell program In an effort to support the research community, Children's Stem Cell Program investigator George Q. Daley, M.D., Ph.D., has made dozens of iPS lines developed at Boston Children's Hospital available for use by other scientists through the Harvard Stem Cell Institute. In 2010, a drug that boosts numbers of blood stem cells, originally discovered in zebrafish in the Boston Children's Hospital laboratory of Leonard I. Zon, M.D., went to clinical trial in patients with leukemia and lymphoma. Awards Nobel Prizes Children's Hospital scientist Dr. John Enders and his team were first to successfully culture the polio virus and were awarded the Nobel Prize in Physiology or Medicine in 1954. Dr. Joseph Murray, chief plastic surgeon at Children's Hospital Boston from 1972 to 1985 was awarded the Nobel Prize in Physiology or Medicine in 1990 for his research on immunosuppression, specifically his "discoveries concerning organ and cell transplantation in the treatment of human disease". Lasker Awards Dr. William Lennox received the Lasker Award in 1951 for his work researching epilepsy. Dr. Lennox organized the American Epilepsy League and the Committee for Public Understanding of Epilepsy.

Dr. John Enders was awarded the Lasker in 1954; the same year he was awarded the Nobel Prize for "achievement in the cultivation of the viruses poliomyelitis, mumps, and measles". Dr. Sidney Farber received the Lasker in 1966 for his 1947 discovery that a combination of aminopterin and methotrexate, both folic acid antagonists, could produce remission in patients with acute leukemia, and for "his constant leadership in the search for chemical agents against cancer". Dr. Porter W. Anderson, Jr. received the Albert Lasker Clinical Medical Research Award with Dr. David H. Smith in 1996 for groundbreaking work in the development and commercialization of the Hemophilus influenza type B vaccine.
