The Center is a collaborative platform for all interdisciplinary issues related to transplantation. It hosts the largest transplant program in Switzerland, including hematopoietic stem cells, kidney, pancreas, liver, heart, lung, small bowel, islet cells, and composite tissues (build-up phase). Research activities are embedded in specific transplant programs and within the SNSF-sponsored Swiss Transplant Cohort Study (www.stcs.ch).
