We are cryopreserving and banking the human umbilical cord blood (UCB) for the clinical application for the hematopoietic stem cell transplantation. UCB is the alternative stem cell source instead of the bone marrow or peripheral blood progenitor cells for the treatment of hematologic malignancies, inherited metaboloc disorders, and congenital immunodeficiencies. We have already cryopreserved more than l,500units of UCB, and more than 38 recipients have already transplanted. We think cryopreservation of UCB is useful not only for the hematopoietic stem cell transplantation but also for the forth coming cell-mediated-immunotherapy using UCB.
