The immunofluorescent staining images in Fig. 3f showed that three GBM cell lines (A172, U87, and U118) internalized substantially more ITGA2-FITC-LPs than non-specific IgG-FITC-LP, whereas normal SVG-P12 cells exhibited no preferable uptake of ITGA2-FITC-LP due their lack expression of ITGA2. The gene discussed is ITGA2; the disease is glioblastoma.
