Fig. 8From: Platelet-membrane-biomimetic nanoparticles for targeted antitumor drug deliveryLocalization of NPs in H22 bearing tumor tissues. Mice bearing H22 tumor were intravenously injected with Cy5.5-labeled CS-pPLGA/Bu NPs and Cy5.5-labeled PLTM-CS-pPLGA/Bu NPs. 24 h later, the tumors were removed and sectioned under frozen conditions followed by staining with an antibody against CD44 (green). The nuclei of cells were visualized using DAPI (blue)Back to article page
