library_construction_protocol: Exosomes were isolated from conditioned media collected at 48-72 hours by serial high speed ultracentrifugation, or using 10% final concentration of polyethylene-glycol and low speed centrifugation. Exosome RNA or cellular RNA was extracted with TRIzol. Library was prepared by using the NEBNext Ultra Directional RNA Library Prep Kit for Illumina (NEB).  Fragmentation step was skipped for exosome RNA.
