  • Hematopoietic System

    Mature blood cells are generated from hematopoietic stem cells (HSCs) in a process called hematopoiesis.  HSCs share the common hallmarks of all stem cells: HSCs can self-renew (can reproduce daughter cells, at least one of which is identical to the parent itself), and HSCs give rise to different kinds of mature blood cells (multi-lineage differentiation). 50 years of research on the hematopoietic system have resulted in HSCs and hematopoiesis being the best studied somatic stem cell system with routine clinical applications such as HSC transplantation.  

    The research in  the Division of Experimental Hematology focuses on understanding the biology of blood cell formation and function and to use this knowledge to develop innovative treatments of genetic and acquired diseases affecting the blood system and cancer.  A better understanding of the development and function of hematopoietic stem and progenitor cells will facilitate the rapid transfer of knowledge into innovative clinical trials in children. This is a highly collaborative effort, including not only faculty from Experimental Hematology and Hematology/Oncology, but also including members of Pulmonary Biology, Allergy/Immunology, Human Genetics, and Bioinformatics at CCRF.
