Camouflaged Hybrid Cancer Cell-Platelet Fusion Membrane Nanovesicles Deliver Therapeutic MicroRNAs to Presensitize Triple-Negative Breast Cancer to Doxorubicin.

ABSTRACT: Camouflaged cell-membrane-based nanoparticles have been gaining increasing attention owing to their improved biocompatibility and immunomodulatory properties. Using nanoparticles prepared from the membranes of specific cell types, or fusions derived from different cells membranes, can improve their functional performance in several aspects. Here, we used cell membranes extracted from breast cancer cells and platelets to fabricate a hybrid-membrane vesicle fusion (cancer cell-platelet-fusion-membrane vesicle, CPMV) in which we loaded therapeutic microRNAs (miRNAs) for the treatment of triple-negative breast cancer (TNBC). We used a clinically scalable microfluidic platform for the fusion of cell membranes. The reconstitution process during synthesis allows for efficient loading of miRNAs in
