The role of Notch signaling during hematopoietic lineage commitment

Abstract

Over the last few years a vast amount of progress has been made in identifying mechanisms controlling lineage commitment and plasticity of hematopoietic precursors to different lymphoid or myeloid lineages. This has been due largely to the ability to identify and isolate rare cell populations in order to investigate their developmental potential, together with the development of inducible and/or tissue specific targeting technology. One family of proteins that has been postulated to be involved in hematopoietic stem cell maintenance as well as in multiple commitment processes during T cell development is the Notch receptors and their ligands. In this review we will summarize recent findings and controversies regarding the role of Notch signaling in the myeloid and lymphoid systems.

Stem cell

In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can differentiate into various types of cells and proliferate indefinitely to produce more of the same stem cell. They are the earliest type of cell in a cell lineage. They are found in both embryonic and adult organisms, but they have slightly different properties in each. They are usually distinguished from progenitor cells, which cannot divide indefinitely, and precursor or blast cells, which are usually committed to differentiating into one cell type.

Lymphopoiesis

Lymphopoiesis (lĭm'fō-poi-ē'sĭs) (or lymphocytopoiesis) is the generation of lymphocytes, one of the five types of white blood cells (WBCs). It is more formally known as lymphoid hematopoiesis. Disruption in lymphopoiesis can lead to a number of lymphoproliferative disorders, such as lymphomas and lymphoid leukemias. Lymphocytes are of the lymphoid (rather than the myeloid or erythroid) lineage of blood cells.

Notch signaling pathway

The Notch signaling pathway is a highly conserved cell signaling system present in most animals. Mammals possess four different notch receptors, referred to as NOTCH1, NOTCH2, NOTCH3, and NOTCH4. The notch receptor is a single-pass transmembrane receptor protein. It is a hetero-oligomer composed of a large extracellular portion, which associates in a calcium-dependent, non-covalent interaction with a smaller piece of the notch protein composed of a short extracellular region, a single transmembrane-pass, and a small intracellular region.
