Cell-derived plasma membrane vesicles extracted from genetically engineered donor cells can selectively target cells based on their receptor expression profi les, as demonstrated by J. C. Stachowiak and co-workers on page 3837.These engineered donor cells have a stable expression of transmembrane protein ligands that contain multiple domains, including a targeting ligand, a spacer and a fl uorophore.
