摘要: UNLABELLED High-dose chemotherapy followed by autologous peripheral blood progenitor cell (PBPC) transplantation is used in the treatment of chemosensitive malignancies. Cryopreservation PBPC 10% dimethyl sulfoxide (DMSO) has been standard procedure most institutions. Infusion cryopreserved with DMSO can be associated toxic reactions such as vomiting, cardiac dysfunction, anaphylaxia and acute renal failure. The grade toxicity experienced patients related to amount present PBPC. lower concentrations would expected reduce toxicity. In recent studies done cells 5%, 4% 2% DMSO, using a reference control, CD34+ were investigated for preservation viability, apoptosis, necrosis. Also mature colony-forming (CFU) cells, specifically myeloid, erythroid progenitors, CFU-megakaryocytes long-term culture-initiating (LTC-ICs) investigated, 5% cryoprotectant. All samples frozen rate-controlled programmed freezer stored vapor phase liquid nitrogen until used. CONCLUSION optimal concentration cryopreserving human vitro. Consequently, some hospitals have started cryoprotectant procedure.
