Fig. 3From: Functional exosome-mediated co-delivery of doxorubicin and hydrophobically modified microRNA 159 for triple-negative breast cancer therapyConfocal microscopy images about the intracellular distribution PKH67-labeled drug-loaded Exo or A15-Exo. Images of MDA-MB-231 cells (a) and B16 cells (b) after incubation with Exo, A15-Exo, Dox, A15-Exo/Dox, Cy5-Cho-miRNA, A15-Exo/Cy5-Cho-miRNA, or Co-A15-Exo for 4 h. Green fluorescence represents PKH67-labeled Exo, red fluorescence represents Dox, and blue fluorescence represents the cell nucleus. Purple fluorescence represents Cy5-labeled miRNA or Cho-miRNA.
