Role of Endothelial Cells in Hematological Malignancies

Abstract

layer that connects vessels to surrounding tissues and controls the ex-Endothelial cells (EC) are key elements of vascularized tissues that form a single-cell layer that connects the vessels to the surrounding tissues. EC participate in the regulation of blood hemostasis, leukocyte homing, acute inflammation, wound healing, and antigen presentation. EC subpopulations are characterized by diverse structures, functions, and molecular profiles. In bone marrow, EC are part of the hematopoietic stem cell vascular and endosteal niche, where they play well-defined roles in hematopoietic stem cell functioning and maintenance, and reside surrounding sinusoids and blood vessels. In the past years, the clinical and pathophysiological roles of EC have been explored due to their contribution to neoangiogenesis and alterations in the vascular endothelium functions in hematological diseases. The present review discusses the EC contribution to pathogenesis of hematological malignancies and their potential use as therapeutic target in these diseases. Abstract
