Fig. 7From: Nano-formulations composed of cell membrane-specific cellular lipid extracts derived from target cells: physicochemical characterization and in vitro evaluation using cellular models of breast carcinomaIsolation of lipid extracts from target cells in preparation of CLENs. The schematic shows the process for preparing CLENs from isolation of the chloroform-soluble fraction which corresponds to the lipid extract phase mixture. The inclusion of cholesterol and DPPE-PEG5000 in CLENs improved drug incorporation, stability, cellular uptake, and cytotoxicity among other formulation propertiesBack to article page
