Blood was collected by retro-orbital puncture. Spleen cells were obtained by mechanical disruption. After Fc receptor blocking (clone 2.4G2, 1:1,000; BD Biosciences), cells were stained with anti-CD4 PerCP-Cy5.5 (clone RM4-5; 1:800; BD Biosciences) or CD4 BV785 (clone RM4-5; 1:800; BioLegend), anti-TCR-β APC (clone H57-597; 1:200; BD Biosciences) or PE (clone H57-597; 1:100; BD Biosciences), anti-NKp46 FITC (clone 29A1.4; 1:300; eBiosciences), anti-CD8 Alexa700 (clone 53-6.7; 1:1,600; BioLegend), anti-CD25 PE-Cy7 (clone PC61; 1:300; eBiosciences), anti-CD62L BV605 (clone MEL-14; 1:800; BioLegend) and anti-CD44 APC-Cy7 (clone IM7; 1:400; BD Biosciences) in PBS/3% FCS. Then anti-Foxp3 eFluor450 (clone FJK-16 s; 1:150; eBioscience) and Ki67-PE (clone B56; 1:50; BD Biosciences) or Ki67-Alexa647 (clone B56; 1:50; BD Biosciences) staining was performed using the eBioscience Foxp3 staining kit according to the manufacturer's instructions. Cells were acquired on a Fortessa flow cytometer and analysed with FlowJo software (TreeStar).

Lungs were digested as above. Colons were incubated with PBS containing EDTA at 37°C for 15 min then digested twice for 35 min with a cocktail of collagenase D (1 mg/ml, Roche), dispase I (0.1 mg/ml, Roche), and DNase I (333 μg/ml, Sigma), smashed and filtered through a 40 μm gauze (BD Biosciences). Single-cell suspensions were then stained for flow cytometry with the following antibodies: CD4 Pacific blue (clone GK1.5), CD103 biotin (clone M290 or 2E7), CD25 PE-cy7 (clone PC61), PD1 PE (clone RMP1-30), GITR FITC (clone DTA-1), and streptavidin APC were purchased from BD Biosciences or Biolegend. FoxP3 AlexaFluor (clone FJK-16a, eBioscience) and Ki-67 PE (clone B56, BD Biosciences) were used in combination with a FoxP3 staining kit (eBioscience).

All rested samples were stained with viability dye and surface antibodies for 30 minutes at 4°C. Then cells were washed and permeabolized using the FOXp3 transcription Factor Staining Set for staining with Ki67 (00-5523, eBioscience, San Diego, CA). The following mouse anti-human antibodies were used: CD3-PE-eFlour 610 (clone UCHT1), CD19-PE-eFlour 610 (clone 61D3), CD14-PE-eFlour 610 (clone HIB19), and CD57-eFlour 450 (clone TBO1) from eBioscience; CD56-BV605 (clone NCAM) and CD117-BV650 (clone 104D2) from Biolegend (San Diego, CA); NKG2A-APC (clone Z199) from Beckman Coulter (Indianapolis, IN); Near-IR LIVE/DEAD Fixable dead cell stain from Life Technologies (San Deigo, CA); and Ki67-PE (clone B56) as part of Transcription Factor Binding set and cocktail of FITC-conjugated KIR antibodies against NKB1 (clone DX9), CD158a (clone HP-3E4), and CD158b (CH-L) from BD Biosciences (San Jose, CA). All flow cytometry was collected on a LSR II flow cytometer (BD Biosciences) and analyzed using Flowjo v10 (Flowjo LLC, Ashland, OR).

T-cell Proliferation and Chemokine Expression

MSCs were seeded onto 96-well plates with appropriate densities. PBMCs from random donor were added into each well with the final concentration of 0.1 × 106 cells per well. 500 ng/mL staphylococcal enterotoxin B (SEB) (Toxin Technology, Sarasota, FL) was used to stimulate the T cells in the PBMCs. Ki67 proliferation assay was performed to measure T-cell proliferation after 4 days. For Ki67 proliferation assay, intracellular flow cytometry staining was performed with BD Cytofix and Cytoperm procedure with the antibodies CD3APCCy7 (Clone SK7) (Biolegend, USA) and Ki67 PE (Clone B56) (BD Biosciences, USA) according to manufacturer instructions (BD Biosciences, San Jose, CA). Samples were acquired in BD FACS Aria flow cytometer, and the results were analyzed in FlowJo software. For non-contact cocultures, MSCs are cultured on the bottom of the well and SEB-activated PBMCs were cultured on the transwell membrane (0.4 µM). Three days later MSCs were lysed and RNA was isolated. Total RNA is converted into cDNA (Qiagen, USA). Quantitative real-time PCR was performed to identify the expression of chemokines.

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.
