“CRYOSTEM Biobank: A National Prospective, Standardized Collection to Better Characterize Allogeneic Hematopoietic Stem Cell Transplantation Complications”

CRYOSTEM was initiated in 2010 to create a multicenter biobank in the field of Hematopoietic Stem Cell Transplantation (HSCT). After initially concentrating on Graft-versus-Host Disease, CRYOSTEM has broadened its focus to all HSCT complications. Thanks to a network of 33 transplant units and 23 Biological Resources Centers, CRYOSTEM has established a standardized collection of high-quality biological samples associated with well-annotated clinical data from donors and patients pre- and post-HSCT. Plasma, dried pellets and viable cells in DMSO are isolated and cryopreserved from blood samples. Currently, the collection has reached almost 200,000 available samples coming from nearly 5,800 patients. Since 2015, CRYOSTEM has provided the national and international scientific community with these samples for large-scale research to improve the knowledge of HSCT complications. Funding statement: CRYOSTEM has been funded by the French government’s “National Investment Program” (call for proposals “COHORTES”, agreement ANR-10-COHO-008) and has also received financial support from INCa (call for proposals “BCB”, agreement 2013-192) and patient associations.
