FIGURE 2.

Immunofluorescent staining of U2OS-SSTR₂ cells and corresponding simulation hypotheses. (A) From left to right, images report nucleus, G, and SSTR₂ stainings for untreated cells (top) and cells incubated with DOTATATE (bottom). Merged image at end highlights colocalization of SSTR₂ with G after 1 h of incubation with DOTATATE. Scale bar = 5 µm. (B) Example of internalized source simulation for cell morphology 2. Nucleus, G, and Cy are reported in green, light blue, and light gray, respectively. Electron tracks are drawn in red, with yellow energy deposition points, which become blue when traversing nucleus.
