The Hackam Lab for Pediatric Surgical, Translational and Regenerative Medicine
David Hackam’s laboratory focuses on necrotizing enterocolitis (NEC), a devastating disease of premature infants and the leading cause of death and disability from gastrointestinal disease in newborns. The disease strikes acutely and without warning, causing sudden death of the small and large intestines. In severe cases, tiny patients with the disease are either dying or dead from overwhelming sepsis within 24 hours. Surgical treatment to remove most of the affected gut results in lifelong short gut (short bowel) syndrome. The Hackam Lab has identified a critical role for the innate immune receptor toll-like receptor 4 (TLR4) in the pathogenesis of necrotizing enterocolitis. The lab has shown that TLR4 regulates the development of the disease by tipping the balance between injury and repair in the stressed intestine of the premature infant. Developing an Artificial Intestine A key goal is to create, in the laboratory, new intestines made from patients’ own cells, which can then be implanted into the patient to restore normal digestive function. This innovative design could transform child development and quality of life in necrotizing enterocolitis survivors without the risks of conventional donor transplant.
