Blood Cells, Molecules, and Diseases, 2013
Blood cells are continually produced from a pool of progenitors that derive from hematopoietic stem cells (HSCs). In vertebrates, the hematopoietic system develops from two distinct waves or generation of precursors. The first wave occurs in the yolk sac, in mammals or equivalent embryonic structure, and produces nucleated primitive erythrocytes that ...

Critical Reviews™ in Immunology, 1998
Hematopoiesis is a developmental process that evolves throughout the lifespan of an individual. Most work in the field has focused on events occurring in the adult bone marrow (BM). In the embryo, blood and endothelial cell generation begins very early after gastrulation, in defined intraembryonic mesodermic sites.

Journal of Allergy and Clinical Immunology, 1994
Cellular turnover of the hematopoietic system is supported by a small population of cells termed hematopoietic stem cells. Stem cells are capable of self-renewal and differentiation into individual lymphomyeloid lineages. Available evidence indicates that the decision of a stem cell to self-renew or differentiate and the decision of a multipotential ...

Paratracheal Extramedullary Hematopoiesis
International Journal of Hematology, 2001Extramedullary hematopoiesis (EMH) is a rare finding in hematology. A 73-year-old female patient with a 1-week history of severe progressive dyspnea was examined, and computed tomography (CT) showed a paratracheal mass 3 cm in size located 1 cm below the vocals cords and causing obliteration of the tracheal airway.

Current Opinion in Hematology, 2001
Hematopoietic reconstitution after transplantation relies on a small number of hematopoietic stem cells that selectively migrate from the bloodstream to the hematopoietic microenvironment. In the first phase of engraftment, an extreme proliferative demand causes a limited stem cell fraction and its progeny to divide continuously, showing a significant ...

Abstract Hematopoiesis, or the process of blood formation, has been extensively studied at both basic and clinical levels. Human diseases such as thalassemia, immunodeficiency, and leukemia represent defects in this process. Approaches to treat these disorders have required a basic understanding of the biology of blood cells.
