Introduction to Stem Cell Therapy and Blood Cancers

Blood cancers represent a diverse group of malignancies originating from various hematopoietic cell lineages, including leukemias, lymphomas, plasma cell disorders, myeloproliferative neoplasms, and myelodysplastic syndromes. Despite significant advancements in understanding their pathogenesis and developing targeted therapies, blood cancers continue to pose a substantial global healthcare challenge. Stem cell therapy has emerged as a promising approach for managing blood cancers, offering the potential for long-term remission and improved patient outcomes. This chapter provides a comprehensive overview of blood cancers, discussing their epidemiology, pathophysiology, and classification. It also traces the history and evolution of stem cell therapy, highlighting key milestones, such as pioneering discoveries, the transition from theory to clinical practice, and recent breakthroughs. By establishing a solid foundation in the understanding of blood cancers and the principles of stem cell therapy, this chapter sets the stage for exploring the intricate mechanisms, clinical applications, and future directions of this therapeutic approach in the subsequent chapters of the book.
