After 48 h in culture, supernatants were collected from each well and stored at −80°C until they were ready for analysis. The supernatants were inactivated using 10% Triton X and probed, using the ProcartaPlex multiplex immunoassay (Affymetrix eBioscience) according to the manufacturer's instructions, for 29 cytokines and chemokines: APO-FAS, BAFF, granzyme B, GRO-α, IFN-α, IFN-γ, IFN-ω, IL-1β, IL-1RA, IL-10, IL-12p70, IL-15, IL-2, IL-21, IL-23, IL-27, IL-29, IL-6, IL-8, IL-10, I-TAC, MCP-1, MIP-1α, MIP-1β, MMP-1, RANTES, SDF-1α, TNF-α, and TRAIL. Samples were then read on a Luminex 200 (Luminex) platform and analyzed using Bio-plex Manager software (Bio-Rad). Previous analyses were also done with a multiplex that included IL-4, IL-5, IL-7, IL-13, IL-17A, IL-18, IL-31, and sCD-40L, but they were found to be unaffected by GS-9620 treatment.

Cardiac-derived monocytes were fluorescence-activated cell–sorted from LVs, 24 hours after the onset of MI. Fluorescence-activated cell–sorted CD45+/CD11b+/Ly6G/Ly6C+ monocytes were counted, seeded at a density of 4.5×105 cells per well, and cultured in complete RPMI (Roswell Park Memorial Institute)-1640 medium (1% exosome-depleted serum; 1% β-mercaptoethanol and penicillin streptomycin). Cells were then stimulated for 24 hours with lEVs or sEVs derived from MI mice at a ratio of 105 lEVs per cell or 103 sEVs per cell to reproduce local concentrations of infiltrating monocytes and those of lEVs and sEVs in the infarcted heart 24 hours postligation. NaCl 0.09% was used as control vehicle. TNFα (tumor necrosis factor alpha), CCL (chemokine ligand) 2, CCL7, IL (interleukin)-4, IL-5, IL-6, IL-10, IL-12, IL-13, and IFNγ (interferon gamma) levels were quantified using ProcartaPlex multiplex immunoassays panels (Affymetrix, eBioscience, France).10 (link),11 (link) Concentrations were calculated from a control standard curve.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
