Autologous peripheral blood progenitor cells cryopreserved with 5 and 10 percent dimethyl sulfoxide alone give comparable hematopoietic reconstitution after transplantation

Abstract

The routines for cryopreservation of autografts vary considerably between transplantation centers, and this makes it difficult to compare different clinical studies. Our results suggest that cryopreservation with 5 percent DMSO alone followed by storage in nitrogen is a simple, highly standardized, and safe procedure for cryopreservation of autologous stem cell graft.
