Warburton cropDavid Warburton, OBE, DSc, MD, MMM, FRCP, FRCS, FRCPCH, leads the Developmental Biology, Regenerative Medicine and Stem Cell Program at the Saban Research Institute, Children’s Hospital Los Angeles. This program comprises more than 20 principal investigators and can accommodate more than 100 scientists at the bench. The mission of this program is to discover the molecular and genetic regulatory networks that mediate organ formation in humans as well as other organisms and, by knowing these facts, to devise and translate regenerative and reparative solutions, including cell-based therapies and tissue engineering, for under developed or damaged human organs. Warburton’s longstanding personal translational research interest in the developing lung arose from his experiences as one of the first people to be board-certified in Neonatal-Perinatal Medicine. Other investigators have since joined in this effort, so that now the members of the program work on devising and translating regenerative solutions for the lung, heart, kidney,  liver, pancreas, gastrointestinal tract, skin and brain. He also directs both a CIRM training program and a CIRM shared laboratory. Warburton has authored more than 300 medical publications, which have been cited more than 10,000 times. He is a fellow of several Royal Colleges and is an Officer of the Order of the British Empire.
