[Notch signaling in the regulation of hematopoiesis].

Notch signaling defines an evolutionarily ancient cell interaction mechanism. The signals transmitted through the Notch receptor, in combination with other cellular factors influence differentiation, proliferation and apoptotic events at all stages of development. Recent advances have elucidated both the biochemical mechanism regulating receptor activation and the molecular participants forming the intracellular signaling cascade. Authors present description of the main signaling components involved in the Notch pathway and how it can affect the growth and function of lymphocytes. Notch signaling is critical during lymphocyte development, and dysregulation of the pathway can give rise to leukemia. It is conceivable that appropriate manipulation of Notch signaling may become a useful tool in addressing a variety of human dysplastic condition and tissue regeneration.
