The IRM will host our fall symposium, Convergent Mechanisms for Building and Breaking the Gut Barrier, on Tuesday, November 15, 2022 in the Smilow Center for Translational Research Rubenstein Auditorium and Commons. This in person event will explore several facets of the critical gut barrier niche, including the stem cell identities and developmental pathways that comprise the barrier, barrier regeneration, and the role of stem cells in malignant transformations.

We invite trainees to submit abstracts for posters and lightning talks!
