Description of Research
Cell Plasticity in Regeneration and Cancer
During development, cells acquire specialized features through a series of differentiation events. Under normal circumstances, adult cells retain their differentiated identities. However, under a variety of experimental and physiological situations, cell identity can shift. This adult cell plasticity can involve an interchange between adult cellular identities (termed "trans-differentiation") or a reversion from a specialized state to a progenitor stated (termed "de-differentiation"). Our laboratory uses genetically engineered mice to understand how cell identity is maintained in vivo. We study cellular plasticity in the context of liver regeneration, diabetes, and cancer - where epithelial-to-mesenchymal transition promotes cell invasion and metastasis. In addition, we have a strong interest in tumor immunology, and the mechanisms by which tumor cells influence their microenvironment. We believe that the ability to manipulate cellular identity in these settings will facilitate the development of novel therapies for cancer and degenerative disease.
