| abstractText | During hematopoiesis, megakaryopoiesis, megakaryocyte differentiation, and thrombopoiesis are regulated at multiple stages, which involve successive lineage commitment steps and proceed with polyploidization, maturation, and organized fragmentation of the cytoplasm, leading to the release of platelets in circulation. However, the cellular mechanisms by which megakaryocytes derive from their progenitors and differentiate into platelets have not fully been understood. Using an Atg7 hematopoietic conditional knockout mouse model, we found that loss of autophagy, a metabolic process essential in homeostasis and cellular remodeling, caused mitochondrial and cell cycle dysfunction, impeding megakaryopoiesis and megakaryocyte differentiation, as well as thrombopoiesis and subsequently produced abnormal platelets, larger in size and fewer in number, ultimately leading to severely impaired platelet production and failed hemostasis. |
