Dr. Warburton directs both the Developmental Biology, Regenerative Medicine and Stem Cell Therapeutics program and the Center for Environmental Impact on Global Health Across the Lifespan at The Saban Research Institute, Children’s Hospital Los Angeles.

A distinguished national and global scientific thought leader in maternal and child health, Dr. Warburton has established and leads a field termed molecular embryology of the lung.  He has published many foundational discoveries in this field, showing how morphogenetic signaling plays a key and necessary role in development of the lung. Subsequently, he has shown that these same processes are clearly replicated, but in an abnormal fashion, in common diseases of the child and adult lung including bronchopulmonary dysplasia, asthma, COPD, emphysema and fibrosis. He has in fact pioneered the concept that abnormal lung development is a precursor to many genetic as well as acquired diseases of the human lung.

Dr. Warburton founded this research program in 1986. It now comprises over 100 researchers seeking to find translational regenerative solutions for pediatric and adult diseases in many organ systems including lung, heart, gut, liver, pancreas, skin, bone and joint, and spinal cord fusion. More than 50 young scientists have become independent investigators under his mentorship during this period of time.

To date, he has made more than 400 contributions to the medical scientific literature in this and related fields, which have been cited over 15,000 times.

In his earlier work as a pioneering neonatologist, Warburton was instrumental in discovering several key parameters of intensive care for premature infants as well as for infants of diabetic mothers. His work has contributed to saving many hundreds of thousands of young lives in the United States and abroad.

Dr. Warburton is active in global health, particularly in emerging countries in Asia and Africa. For example, he has worked in Mongolia to improve child and maternal health for more than 15years. He founded a Department of Environmental Health at the National Mongolian University of the Medical Sciences and has supervised more than 20 graduate students working to improve the impact of air pollution on health across the lifespan in that country.

Dr. Warburton was born and educated in London at St. Thomas’s Hospital, and emigrated from the UK in 1976 to become a junior physician at Harvard and Brown. His most seminal medical scientific work has been conducted in Los Angeles. He has been honored by the Queen of England with the Most Excellent Order of the British Empire for his collaborative work in UK/USA health care research and has been appointed a Fellow of several Royal Colleges.

Research OverviewLungimage.jpg

David Warburton, MD leads the Developmental Biology and Regenerative Medicine Program at the Saban Research Institute. 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. By knowing these facts to devise and translate regenerative and reparative solutions for under developed or damaged organs, including stem cell based therapies and tissue engineering. 

Dr. Warburton's long standing personal interest has been in doing this with the lung, which arose from his experiences early in his career as one of the first physicians to be Board Certified in Neonatal-Perinatal Medicine. Other investigators have joined this effort so the Program now works on regenerative solutions for:

  • Lung
  • Heart
  • Kidney
  • Bladder
  • Intestines
  • Liver
  • Pancreas
  • Skin 
  • Brain 

Key Recent Findings

  • The role of key proteins in wound healing in the tiny air sacs in the lungs known as "alveoli" that could lead to new therapies for children and adults.
     
  • Determined that the damaged AEC2 environment was chemoattractive to uncommitted human amniotic fluid stem cells (hAFSCs). Migration of the hAFSCs to the AEC2s increased 20-fold over normal, and the stem cells not only attached themselves within an in vitro AEC2 wound, they accelerated its healing. 
     
  • Blood vessels determine the reproducible three-dimensional branching pattern of lung airways.
  • The research team employed a breakthrough computer-based three-dimensional reconstruction technique in its studies to view lung tissue and its growth processes at work.

  • Eya1 phosphatase controls fate of embryonic lung epithelial stem cells.

  • Investigators have pinpointed how the early-stage human embryo organizes stem cells for particular functions in the body. With this information scientists can now understand how blood vessels direct the formation of organs from these stem cells. Additionally, stem cells are being isolated from amniotic fluid and show promise for therapeutic purposes.
