TITLE:
Development and Renewal in the Mouth and Gut
ABSTRACT:
Dr. Klein’s research focuses on understanding how organs form in the embryo and how they regenerate in the adult, with a particular emphasis on the processes underlying craniofacial and dental development and renewal, as well as understanding how intestinal stem cells and their niche enable GI tract regeneration.
