Hybrid cell-like vesicles were prepared by coassembling (glyco)dendrimersomes with bacterial membrane vesicles (BMVs) derived from E. Coli. These assemblies incorporated transmembrane proteins such as the small fusion protein MgrB tagged with a red fluorescent protein, and glycoconjugates such as lipopolysaccharides and glycoproteins from E. Coli. In future work, coassembly of (glyco)dendrimersomes with mammalian including human cell membranes will be a focus with the goal of developing new systems for biomedical application.
