Fig. 3From: Docetaxel-loaded M1 macrophage-derived exosomes for a safe and efficient chemoimmunotherapy of breast cancerThe cellular uptake behavior of the exosomal vesicles (M1-Exo or M1-Exo) toward 4T1 cancer cells after 6 h incubation. In the CLSM images, cell nuclei were stained by DAPI (blue), while the exosomes were stained by fluorescent dye PKH67 (green). The scale bar is 20 µmBack to article page
