Transferring hematopoietic stem cells and immune cells continues to be a promising therapeutic alternative and a fascinating area of cell biology as well as a field of persistent procedural problems. This explains why substantial parts of basic research on cell growth and differentiation, immune tolerance and antitumor effects, gene transfer, minimal residual disease and supportive care have settled around clinical transplantation in hematology and oncology. This second volume updates the current role of allogeneic and autologous transplantation in leukemias, lymphomas and solid cancers, including controversial strategies and novel experimental approaches. Specialist contributions help to ensure first-hand information and further the debate on how medics can work and cooperate more effectively for the benefit of patients.
