Scientific inspiration can come from anywhere — a person, an event, even an experiment gone awry. But perhaps nothing can drive innovation more powerfully than the passion born of tragedy. Or, in Douglas Melton’s case, near tragedy. The co-director of the Harvard Stem Cell Institute (HSCI) is one of the leading figures in the search for cures for presently incurable diseases, and his breakthrough work is challenging many long-held beliefs about the ways biology and human development work.
But it was a very personal experience that brought Melton to stem cells, one that 17 years later he still finds difficult to discuss. When his son Sam was 6 months old, he became ill with what his parents thought was a cold. He woke up with projectile vomiting and before long began taking short, shallow breaths. After several hours, he started to turn gray, and Melton and his wife Gail brought the baby to the emergency room. For the rest of that afternoon, doctors performed test after test, trying to figure out what was wrong. “It was a horrific day,” says Melton. (See the top 10 medical breakthroughs of 2008.)
It was not until that evening that a nurse thought to dip a testing strip into Sam’s urine and they finally got a diagnosis. The boy’s body was flooded with sugar; he had Type 1 diabetes. Then, as now, the disease had no cure, and patients like Sam need to perform for themselves the duties their pancreas cannot — keeping track of how much glucose they consume and relying on an insulin pump to break down the sugars when their levels climb too high. The diagnosis changed not only Sam’s life but the lives of his parents and older sister Emma as well. Throughout Sam’s childhood, Gail would wake every few hours during the night to check his blood sugar and feed him sugar if his concentration fell too low or give him insulin if it was too high. “I thought, This is no way to live,” says Melton. “I decided I was not just going to sit around. I decided I was going to do something.”
