My laboratory use mouse genetics to understand the function of Hox genes during mammalian organogenesis. Hox genes are a highly conserved group of transcriptional regulators that are critical for directing numerous patterning processes during development and that direct repair and regeneration throughout life. The laboratory has investigated many organ systems and current projects focus on the musculoskeletal system and lung. Using primarily advanced mouse genetics, we are dissecting Hox gene function in both development and response to injury and disease. Developmentally, Hox genes are critical for the proper differentiation and integration of cell and tissue types and play key roles in the formation of a functional organ. In response to injury and disease, Hox genes are up-regulated in the same regionally-restricted manner they are employed developmentally, and these genes play important roles in repair and regeneration after tissue damage. Our long-term goal is centered on understanding the downstream mechanisms controlled by Hox genes to direct these developmental and repair processes in mammals and to elucidate how this information can be used to improve potential regenerative therapies in response to injury and disease.
