Figure 5. Analysis of nanoparticle co-localization with KR158 cells in vivo.
(A) Bioluminescence image of mouse bearing KR158 intracranial tumor indicated by dotted white circle. (B) H&E (left) and Fn14 (right) staining of KR158 tumor. Fn14 staining is shown in the expanded view of boxed region from H&E stain. (C) Flow cytometry analysis of PLGA-PEG and PLGA-PEG-ITEM4 nanoparticle co-localization in vivo with luciferase-positive KR158 cells in intracranial tumors. Values shown are mean +/− SD (n=3). Data analyzed for significance using Student’s t-test. *P < 0.05.
