The Banff Foundation for Allograft Pathology was established in 2013 and organizes conferences to develop consensus classifications for interpreting transplant biopsies. The Banff Schema, first developed at a 1991 meeting in Banff, Canada, set worldwide standards for biopsy interpretation. The Foundation includes working groups that refine classifications based on research feedback. As technologies like stem cell-grown organs emerge, the Foundation must adapt to remain relevant by including new member specialties. The Banff process demonstrates how medical knowledge can advance through collaborative consensus-building.
