(A) The scheme illustrated the preparation of mesenchymal stem cell membrane-coated gelatin nanogels (SCMGs) and the tumor targeting property; (B) the surface protein analysis of SCMGs to certify the cell membrane coating; (C) confocal fluorescence images for the cell uptake of SCMGs which illustrated the colocalization of green labeled gelatin nanogels and red labeled stem cell membranes; (D) in vivo fluorescence imaging of mice after intravenous injection of SCMGs, that illustrated the enhanced tumor targeting and prolonged circulation after stem cell membrane coating.
