Abstract
Description
technical field
[0001] The present invention relates to compositions and methods for modulating platelet levels. Background technique
[0002] Platelets, also known as thrombus cells, are anucleated cell fragments present in mammalian blood that mediate clot formation and hemostasis. In addition, platelets release growth factors that play an important role in the repair and regeneration of connective tissue and can promote wound healing. Platelets are the final differentiation products of megakaryocytes (MK), which in turn originate from pluripotent stem cells of the bone marrow. Although humoral factors such as thrombopoietin (TPO) were found to affect different cellular steps of megakaryocyte development, the complex mutation, differentiation, and localization processes that begin with pluripotent stem cells and end with platelets are not fully understood.
[0003] The average lifespan of platelets is about 5 to 10 days, and their physiological blood levels are normally ...
