Hematopoietic stem cells is a fundamental concept within biomedical research referring to the multipotent stem cells found primarily in the bone marrow that are responsible for generating all mature blood cell lineages. This research area investigates their unique biological properties, including self-renewal and differentiation potential, the molecular mechanisms regulating their fate and function, and their critical role in hematopoiesis, tissue regeneration, and various hematological disorders, providing foundational knowledge for therapeutic applications such as bone marrow transplantation.
