Abstract
A process of hematopoietic stem cell harvesting, processing, preservation, and infusion is basically important for hematopoietic stem cell transplantation. Appropriate these procedures lead to a high quality of hematopoietic stem cell products, resulting in good clinical outcomes. These procedures should be done strictly according to several guidelines published by The Japan Society for Hematopoietic Cell Transplantation, The Japan Society for Transfusion Medicine and Cell Therapy, and Japan Marrow Donor Program. In this review, the current status of these procedures in Japan as well as in other countries is described.
