Updated project metadata. To understand the mechanism by which AML-EVs may enforce quiescence, we performed tandem mass tag (TMT) proteomic profiling of in vitro cultured c-Kit+ hematopoietic stem and progenitor cells (HSPC) (to obtain the minimum required amount of protein lysates) treated with extracellular vesicles (EVs) for 48 hours from human HL-60 or Molm-14 cell cultures versus controls.
