Over the past 60 years, the field of hematopoietic cell transplantation (HCT) has evolved from experimental animal models of marrow transplantation to curative therapy for tens of thousands of people yearly who are affected by a wide variety of marrow failure states, myeloid and lymphoid malignancies, immune deficiencies, and inborn errors of metabolism. Advances in transplantation immune biology combined with improvements in supportive care have made this evolution possible and have ushered in the modern era of HCT. This chapter discusses the biologic principles and clinical applications of HCT along with its future applications. Selected results demonstrating important principles are highlighted.

The successful clinical application of hematopoietic cell transplantation (HCT) required a century of key developmental discoveries (Table 23–1). Between 1868 and 1906, European and American investigators established that marrow cells were the source of blood cell production. In 1939, the first documented human marrow transplant was performed in a patient with gold-induced marrow aplasia.1 The patient was infused intravenously with marrow from a brother with an identical ABO blood type. The transplant was not successful, and ...
