Clinical Core

The Clinical Core of the Center for Cell Signaling in Gastroenterology supports faculty research by facilitating access to human biospecimens through two primary objectives:

  • Centralizing, expediting and facilitating access to digestive disease-related biospecimens
  • Enhancing digestive disease-related biospecimen repositories within Mayo Clinic


The director of the Clinical Core is Lisa A. Boardman, M.D.


The Clinical Core offers several services, primarily to Center for Cell Signaling in Gastroenterology faculty and their laboratory team members, including:

  • Centralized access to 18 participating Mayo Clinic GI biobanks and other institutional biospecimen resources
  • Institutional Review Board (IRB) protocol development and modification
  • Identification of biospecimens meeting specific research criteria
  • Pathologist review of tissues
  • Biospecimen processing request form coordination
  • De-identified, phenotypic and demographic data
  • Standardized epidemiological questionnaires for GI biobanks
  • Coordination of fresh tissue acquisition from surgical pathology
  • Fecal collection kits and storage for microbiome-related projects
  • Inventory management software deployment and customization


Research teams from NIDDK-funded Digestive Disease Research Core Centers outside of Mayo Clinic may access select core services as resources permit by emailing requests to or by calling 507-293-1449.
