Transfusion medicine has grown exponentially in recent decades. The current concept of transfusion medicine includes both transfusion of blood components and hematopoietic transplants, cellular and tissue therapy and immunotherapy, areas that integrate the curriculum of the University Master’s Degree in Transfusion Medicine and Cellular and Tissue Therapies. This University Master’s Degree has been conceived by the best international experts in this field and is linked to the Chair of Transfusion Medicine and Cellular and Tissue Therapy (CMT3), formed by members of Universitat Autònoma de Barcelona, the Salut i Envelliment Foundation and the Blood and Tissue Bank. From 2022-23, the Master’s Degree expanded its international dimension by offering a joint biennial degree with Leiden University Medical Centre (LUMC), specialising in clinical transfusion, a leader in transfused cellular therapies for regenerative medicine in the Netherlands and linked to Sanquin, the Dutch blood and tissue bank. The collaboration between Universitat Autònoma de Barcelona, Leiden University, Sanquin and the Blood and Tissue Bank forms one of the most potentially powerful international alliances for the creation and transmission of knowledge in the field of Cellular and Tissue Transfusion Medicine, and with the present Master’s Degree as a spearhead with the greatest impact.
