EFFICACY OF HEMATOPOIETIC STEM CELLS STORED SHORT TERM AT +4 ºC

Abstract

Autologous peripheral blood stem celi transplantation is a widely used treatment modality in hematological malignancies in last years. Progenitor cells collected from bone marrow or peripheral blood are stored in liquid nitrogen tanks (-180 ºC) or in mechanical freezers (-80 ºC). Cryopreservation is a relativety difficult and time consuming procedure. Volume overload and the toxicity of cryoprotectant agent are other majör problems. In this study, peripheral blood progenitor cells collected from 8 patients by 1-3 leucapharesis were refrigerated at +4 ºC without applying any procedure. After high dose therapy these products were reinfused to patients in 24 - 48 hours. Neutrophil engraftment (>500//,ıL) occurred in ali patients median at 15nd1 (11-43) day. Platelet engraftment (>20000//uL) occurred in ali but one patient who died due to progressive myeloma at 25nd1 (12-49) day. Storage of peripheral blood progenitor cells in refrigerator at +4 ºC is a very easy method that can be applied in every transplantation center. İt is also cheaper and there is no need to any other troublesome freezing procedures. The results of study showed that this method can be used safely in short lasting conditioning regimens.
