In Vitro Cellular Phagocytosis Experiment of C-GAP. A Representative Images of C-GAP Internalization by SCC-VII, SCC-9, and SCC-15 Cells Detected by Immunofluorescence Staining. B, C Semi-Quantitative Analysis of C-GAP Internalization Efficiency by SCC-VII, SCC-9, and SCC-15 Cells (n = 5, one-way ANOVA test). D–F Observation of C-GAP Internalization Process by SCC-VII Cells under TEM, Highlighting Cellular Structures Including Nucleus (N), Nucleolus (NU), Mitochondria (M), Rough Endoplasmic Reticulum (RER), and Autophagolysosome (ASS), with Red Arrows Indicating C-GAP After Cellular Phagocytosis. The data are presented as the means ± SDs. ns P > 0.05, *P < 0.05, **P < 0.01, ***P < 0.001
