MM-EV effect on HSPC colony formation. (A) Representative photos of colony-forming unit (CFU) assay for HSPCs after 20 h of treatment with MM-EVs 400 μg (left) and means of the total number of colonies after treatment with two doses of MM-derived EVs (MM-EVs 200 μg, MM-EVs 400 μg; right); (B) representative photos of CFU-Granulocyte, Macrophage (CFU-GM), CFU Macrophage (CFU-M), CFU Granulocyte (CFU-G), CFU Granulocyte, Erythrocyte, Macrophage, Megakaryocyte (CFU-GEMM), and Burst-Forming-Unit Erythrocyte (BFU-E) after treatment with MM-EVs 400 μg; means of the total number (C) and proportion (D) of all type of colony after treatment with two doses of MM-derived EVs. The bar graphs represent the average with SD from three independent experiments. MM, multiple myeloma; EVs, Extracellular vesicles; HSPC, hematopoietic stem and progenitor cells.
