ILC2s were sorted from homogenized mouse lung, skin, and small intestine as live (DAPI) CD45+Lin(CD3,CD4,CD5,CD8α,CD11b,CD11c,CD19,NK1.1, NKp46,Gr-1,F4/80,Ter-119,DX5)Il5RFP+ cells. BM cells were sorted as live CD45+Lin-Thy1+Arg1YFP+ cells. Cells were sorted using a MoFlo XDP (Beckman Coulter) into ice-cold 0.5% BSA in PBS and processed on the same day through the Chromium Single Cell 3’ v2 Library Kit (10X Genomics) per the manufacturer’s protocol. Each channel was loaded with 5000–25000 cells from each tissue, yielding 400 single cells (neonatal small intestine), 3030 single cells (neonatal skin), 6348 single cells (neonatal lung), 7547 single cells (adult small intestine), 6115 single cells (adult skin), 11615 single cells (adult lung), and 4990 single cells (adult BM) for analysis. The cells were then partitioned into Gel Beads in Emulsion in the instrument, where cell lysis and barcoded reverse transcription of RNA occurred, followed by amplification, shearing, and 5’ adaptor and sample index sequence ligation. Libraries were sequenced on an Illumina HiSeq 4000. Single Cell 3’ libraries use standard Illumina sequencing primers for both sequencing and index reads. They were run using paired-end sequencing with single indexing where Read 1 is 26 cycles and Read 2 is 98 cycles.

HDM-treated dorsal neck skin from 4 pooled IL31RAKO and 4 pooled WT C57Bl/6 mice was digested and prepared for flow cytometry as above. The live (DAPI-negative) CD45 + cell fraction of each sample was sorted using a Moflo XDP (Beckman Coulter) directly into ice-cold 0.5% BSA in PBS, and immediately processed through the Chromium Single Cell 3′ v2 Library Kit (10X Genomics) per the manufacturer's protocol by the UCSF Genomics Core Facility of the UCSF Institute for Human Genetics. Each channel was loaded with 30,000 cells per sample. The cells were then partitioned into Gel Beads in Emulsion in the instrument, where cell lysis and barcoded reverse transcription of RNA occurred, followed by amplification, shearing, and 5′ adaptor and sample index attachment. Libraries were sequenced on an Illumina HiSeq 4000. Single Cell 3′ libraries used standard Illumina sequencing primers for both sequencing and index reads and were run using paired-end sequencing with single indexing where Read 1 is 26 cycles and Read 2 is 98 cycles.

Single cells were purified by FACS sorting before library preparation and single-cell libraries were prepared with the Chromium Single Cell 3' Reagent Kits v2 (10x Genomics) as per manufacturer's instructions. Briefly, sorted cells in suspension were first prepared as gel beads in emulsion (GEMs) on Single Cell 3' Chips v2 (10x Chromium) using the Chromium Controller (10x Genomics). Barcoded RNA transcripts in each single cell were reverse transcribed within GEM droplets. cDNA was purified with DynaBeads MyOne Silane beads (Invitrogen) and then amplified for subsequent library construction. Sequencing libraries were prepared by fragmentation, end-repair, ligation with indexed adapters and PCR amplification using the Chromium Single Cell 3' library kit v2 (10x Genomics). Nucleic acid was cleaned up after each steps using SPRIselect beads (Beckman Coulter). Libraries were then quantified by Qubit and real-time quantitative PCR on a LightCycler 96 System (Roche).

CD45+CD3+CD8+ T-cells used for single-cell RNA-sequencing (scRNA-seq) were dissociated into single cells from the ischemic muscle of Leprdb/+ or Leprdb/db mice as aforementioned. Single-cell libraries were prepared with the Chromium Single Cell 3' Reagent Kits v2 (10x Genomics) as previously described 15 (link). Briefly, sorted single cell suspension was prepared as gel beads in emulsion (GEMs) on Single Cell 3' Chips v2 (10x Chromium) using the Chromium Controller (10x Genomics). Barcoded RNA transcripts in each single cell were reverse transcribed within GEM droplets. Complementary DNA (cDNA) was purified with DynaBeads MyOne Silane beads (Invitrogen) and then amplified for subsequent library construction. Sequencing libraries were prepared by fragmentation, end-repair, ligation with indexed adapters, and polymerase chain reaction (PCR) amplification using the Chromium Single Cell 3' library kit v2 (10x Genomics). Nucleic acid was cleaned up after each step using SPRIselect beads (Beckman Coulter). Libraries were then quantified by Qubit and real-time quantitative PCR on a LightCycler 96 System (Roche).

To generate single-cell suspensions, cells were trypsinized as described. After stopping the reaction, cells were washed with PBS and filtered through a 40 µm cell strainer. Cells were washed, resuspended in PBS supplemented with 0.05% bovine serum albumin, and filtered through a 20 µm cell strainer. Single-cell suspensions were loaded following the Chromium Single Cell 3′ Library Kit v2 (10× Genomics, Pleasanton, CA, USA) protocol to generate cell and gel bead emulsions. Reverse transcription, cDNA amplification, and sequencing library generation were performed according to manufacturer’s protocol. Each library was sequenced in one lane of the NextSeq500 (Illumina, San Diego, CA, USA; high-output mode, paired-end, 26 × 49 bp).

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.
