Progress on role of exosomes derived from leukemia cells / 中国病理生理杂志

ABSTRACT

Exosomes are bilayer-lipid membrane nanovesicle from almost all living cell types which are in-volved in intercellular substance transporting and signaling communication .Exosomes are 30 ~120 nm in diameter , can transfer bioactive molecules including DNA , RNA, microRNA, protein as well as lipids derived from parents ' cells to re-cipient cells by body fluids , and specifically influence their physiological or pathological conditions .Leukemia is due to malignant proliferation of hematopoietic stem and progenitor cells .It was reported that leukemia cells derived exosomes play a key role in disease progression , drug resistance , and predict prognosis .This paper will outline the role of exosomes de-rived from leukemia cells and provide important information to help explore the molecular pathogenesis , biomarker as well as therapeutic target of leukemia .
