ITGA2 and glioblastoma: The obtained FITC-dextran encapsulating, ITGA2 antibody or IgG-conjugated liposomes (ITGA2-FITC-LP or IgG-FITC-LP) were incubated with three GBM cell lines (A172, U87, and U118) and SVG-P12 cells, and we quantified the cell uptake of these liposomes by measuring the cellular fluorescent intensity changes.
