JSHCT (Japan Society for Hematopoietic Stem Cell Transplantation) was initiated as The Nation-wide Gathering for Friendly Discussion about Bone Marrow Transplantation in 1978 and changed its naming to Bone Marrow Transplantation Study Group in 1980. At the 13th Annual Meeting in 1991, when the 2nd Annual Meeting of Asia-Pacific Blood and Marrow Transplantation Group (APBMT) was jointly organized, the group expanded its membership to nurses and the other co-medicals, had the bylaws and elected the officers. At the 19th Annual Meeting in 1996, the group developed to Japan Society for Hematopoietic Cell Transplantation (JSHCT) and in 2006, JSHCT was approved to be NGO under the Japanese Law. JSHCT has now 2,300 members of physicians, nurses, the other co-medicals, donor and clinical coordinators, volunteers and pharmaceutical companies. JSHCT has been primarily the academic society for transplant clinicians but recently it is expanding its interests to cell therapy and regenerative medicine. The core activities of JSHCT are consisted of organizing annual congress, publishing quarterly JSHCT Letters, managing the data centers for transplant patient and donor registration, publishing Annual Report of Nationwide Survey for transplant recipients, promoting more than 20 working groups, steering more than 10 committees and publishing multiple guidelines for hematopoietic stem cell transplantation. The members of JSHCT are playing key-roles for steering JMDP (Japan Marrow Donor Program), JCBBN (Japan Cord Blood Bank Network), APBMT (Asia-Pacific Blood and Marrow Transplantation Group) and WBMT (Worldwide Network for Blood and Marrow Transplantation). JSHCT is also deepening the relationships with other national and international academic societies. JSHCT has the home page (https://www.jshct.com/) through which one can get more information of our society.
