MTA1 loaded exosomes enhanced gemcitabine mediated tumor growth inhibition in vivo. (1) Electron microscopy of exosomes (A). (2) WB assay tests markers of exosomes (B). (3) WB assay for MTA1 knockdown efficiency by siMTA1-loaded exosomes (Exo_siMTA1) (C). (4) Immunofluorescence (IF) assay for up taking of siMTA1-loaded exosomes by MCF-7 cells (D). (5) IF assay tested MTA1 knockdown efficiency by siMTA1-loaded liposomes (LIP_siMTA1) and Exo_siMTA1 (E). (6) Experiments process in vivo (F). (7) Tumor volume (1#: Exo + GEM, 2#: Exo_siMTA1, 3#: Exo_siMTA1 + GEM) (G, I). (8) Weight of mouse (H). (9) (J) Tumor growth inhibition rate (2#: Exo_siMTA1, 3#: Exo_siMTA1 + GEM). (10) H&E staining (K) and ki-67 staining (L).
