Figure 4From: Tissue distribution of DNA-Hsp65/TDM-loaded PLGA microspheres and uptake by phagocytic cellsMicrographs of peritoneal macrophages after microspheres phagocytosis. Transmission electron microscopy of peritoneal macrophages incubated with microspheres for 3 days (A), 5 days (B), 8 days (C), 10 days (D) and 15 days (E). Microspheres persisted inside the cells and remained in vesicles during all the time points analyzed. (F): Peritoneal macrophages without exposure to microspheres.Back to article page
