Dr. Frank McKeon was extremely fortunate to receive his graduate and postdoctoral training in the Department of Biochemistry & Biophysics at the University of California, San Francisco under the guidance of Prof. Marc Kirschner, as well as to be recruited by Prof. Howard Green, the pioneer in somatic stem cell cloning, as an assistant professor at the Harvard Medical School.

McKeon’s laboratory has since studied aspects of cell cycle control, stem cell regulation, and developmental biology and has mentored a number of highly talented postdocs, graduate, undergraduate, and even high school students, many of whom have become leaders in their fields. Their discovery of the p53 homolog p63 and its role as a master regulator of stem cells of stratified epithelia has aided the understanding of regenerative processes in stratified epithelial organs such as the skin, prostate, and mammary gland. In addition, the monoclonal antibodies the lab generated to p63 turned out to be exceedingly useful for accurate diagnoses of prostate cancer and now is included in as an FDA- cleared test used on a large fraction of prostate and breast cancer workups worldwide.

More recently, McKeon’s lab has developed novel stem cell cloning strategies that have significantly advanced concepts of lung regeneration, understanding the origins of highly aggressive upper gastrointestinal tract diseases, and the stem cell biology of the gastrointestinal tract in general and how this information can be used to address the genetics and pathophysiology of inflammatory bowel disease. In particular, the lab’s work on acute respiratory distress syndrome (ARDS) due to H1N1 influenza virus infections was the first to demonstrate lung regeneration. This work also identified and cloned the lung stem cell responsible for this alveolar regeneration and demonstrated that these cloned p63/Krt5 stem cells have a remarkable capacity to new alveoli during autologous transplantations. The lab’s efforts on upper GI tract cancers, which have very poor prognosis, have focused on the cancers’ metaplastic precursors such as Barrett’s esophagus which arise 20 years before the lethal malignancies. The lab has cloned the stem cells of these precursors, demonstrated that they arise from a lineage of cells distinct from those of the local epithelia, and are developing means of targeting such cells in preemptive strategies. Finally, McKeon foresees that the lab’s cloning technologies are likely to transform the understanding of the epithelial contributions to chronic inflammatory diseases of the gastrointestinal tract such as Crohn’s, ulcerative colitis, and chronic or recurrent infections.
