Fig. 7From: Dual-labeled nanoparticles based on small extracellular vesicles for tumor detectionIn vivo optical imaging of dual-sEVs. A In vivo optical imaging of tumor-bearing mice 24 h after i.v. injection in the lateral (left) and prone positions (right). B Ex vivo biodistribution of the excised organs (brain, spleen, kidneys, liver, tumor, heart, lungs; n = 11). Detailed quantification of the brain (control organ) compared to U87 tumor tissue. * p < 0.05. Data is represented as mean ± SDBack to article page
