Freshly excised hearts were minced on ice and digested in serum free Iscoves DMEM supplemented with 2mg/mL of Collagenase Type 2 (Worthington, Cat #LS004176) and 0.02mg/mL of Deoxyribonuclease I from bovine pancreas (Sigma, Cat #DN25-100MG) at 37°C for 30 minutes. These cell suspensions were then neutralized with IDMEM containing 10% FBS and filtered through 0.45μm strainer before blocking with 2.4G2 (BD Pharmingen, Cat #553141) for 30 minutes on ice, and staining with Gr-1-APC (Clone RB6-8C5, eBioscience), CD11b-APC-Cy7 (M1/70, BD Pharmingen), Ly 6C-PerCP-Cy5.5 (HK1.4, eBioscience), Ly6G-FITC (1A8, eBioscience), MHC-II PE-Cy5 (M5/114.15.2, eBioscience), MerTK-PE (DS5MMER, eBIoscience), F4/80-PE-Cy5 (BM8, eBioscience) and CD64-Biotin (X54-5/7.1, Biolegend and used in conjunction with Streptavidin PE-Cy7, eBioscience) antibodies for 30 minutes on ice protected from light. Cells were washed with PBS prior to flow cytometry. The samples were then analyzed on BD LSR-II (UAB Flow Cytometry Core Facility). Neutrophils were identified as Gr-1+CD11b+Ly-6G+F4/80-MHC-II-. Cardiac macrophages were first gated on F4/80+CD11b+ cells and further gated for expression of MerTK and CD64. Flow cytometry data were analyzed using FlowJo software. Percent neutrophils and macrophages were determined as (Percent live gated cells from the heart) x (percent positive).

To determine the amount of LinnegCD45negVybrpos (CH) cells, PBMCs derived from fractured and naive mice were collected in FACS buffer (PBS containing 2% heat-inactivated foetal bovine serum) and stained for 10 min at 4 °C with Lineage Cell Detection Cocktail-Biotin antibody (Lin), (Miltenyi Biotec, Bergish Gladbach, Germany). A Streptavidin PE-Cy7 (eBioscience, San Diego, CA, USA) was used for indirect staining to detect the biotinylated antibody cocktail. After washing, cells were stained with APC rat anti-mouse CD45 antibody (clone 30-F11) (BD Biosciences). A double staining with Vybrant DyeCycle Green Stain and Sytox AADvanced Dead Cell Stain (Molecular Probes, Milan, Italy) was used to discriminate debris, live and dead cells. A set of microsphere suspensions (2, 4, 6 μm) (Molecular Probes) was used as size references.
CH cells were sorted, with high purity mask, from naive and RFP-Tg mice. All experiments were performed on BD FACSAria II. Data were analyzed using BD FACSDiva software.

Analysis by flow cytometry of the cell surface marker profile was conducted on T cells exposed to ASC conditioned medium. A total of 3 × 105 cells were concentrated by centrifugation at 300g for 5 minutes, suspended in 50 μl PBS and labeled with the primary antibodies. The following primary antibodies were used: Anti-mouse CD3-biotin (eBiosciences, San Diego, CA, www.ebioscience.com), anti-mouse CD4-PE (eBiosciences), and anti-mouse CD8-PeCy5 (eBiosciences). The samples were incubated for 30 minutes at room temperature. After three washes with PBS, cells were incubated in secondary antibody streptavidin-PeCy7 (eBiosciences) for 15 minutes at room temperature. Additional analysis was performed with anti-mouse CD62L-APC/Cy7 (Biolegend, San Diego, CA, www.biolegend.com) and anti-mouse CD44-Alexa fluor 700 (Biolegend). The samples were then analyzed with Galios Flow Cytometer (Beckman Coulter, Brea, CA) running Kaluza software (Beckman Coulter). To assay cells by forward and side scatter of light, FACScan was standardized with microbeads (Dynosphere uniform microspheres; Bangs Laboratories Inc.; Thermo Fisher Scientific; Waltham, MA). At least 10,000 events were analyzed and compared with unstained cells.

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.
