Single-cell RNA-seq Library Preparation

The scRNA-seq libraries were generated using the 10× Genomics Chromium Controller Instrument and Chromium Single Cell 3′ V3 Reagent Kits (10× Genomics). Briefly, cells were concentrated to 1,000 cells/μL and approximately 8,000–10,000 cells were loaded into each channel to generate single-cell gel bead-in-emulsions (GEM), which resulted in the expected mRNA barcoding of 3,000–8,000 single cells for each sample. After the reverse transcription step, GEMs were broken and barcoded cDNA was purified and amplified. The amplified barcoded cDNA was fragmented, A-tailed, ligated with adaptors and index PCR amplified. The final libraries were quantified using a Qubit High Sensitivity DNA assay (Thermo Fisher Scientific) and the size distribution of these libraries was determined by a High Sensitivity DNA chip on a Bioanalyzer 2200 (Agilent). All libraries were then sequenced by an Illumina sequencer (Illumina) on a 150 bp paired-end run.

Single cells or Clusters were captured using the 10× Genomics Chromium Controller Instrument (10× Genomics, Pleasanton, CA) and ChromiumTM Single Cell 30 Reagent Kits v1 or v2 according to manufacturer’s instructions. Briefly, the suspended cells were loaded on a Chromium controller Single-Cell Instrument to generate single-cell Gel Bead-In-Emulsions (GEMs). After breaking the GEMs, the barcoded cDNA was then purified and amplified (14 PCR cycles) on the operative day. Subsequently, the cDNA was fragmented, A-tailed and ligated with adaptors. Finally, ten and 14 cycles of PCR amplification for the single cell and cluster derived libraries was performed to enable sample indexing. The libraries were sequenced on an Illumina HiSeq 4000 or NovaSeq instruments. Information on the number of single cells or Clusters captured, total cDNA yield as well as number of reads per cell or cluster can be found in Supplementary Fig. 1b.

As described previously, mouse livers were digested to obtain single-cell suspensions A [20 (link)]. Dissociated single cells were stained with AO/PI for viability assessment using a Countstar Fluorescence Cell Analyzer. The scRNA-seq libraries were generated using the 10× Genomics Chromium Controller Instrument and Chromium Single Cell 3’V3.1 Reagent Kits (10× Genomics, Pleasanton, CA, USA) according to the recommendations of the manufacturer. scRNA-seq data analysis, including cell communication analysis, quantitative set analysis of gene expression (QuSAGE) analysis, and pathway analysis were performed by NovelBio Bio-Pharm Technology Co., Ltd., using the NovelBrain Cloud Analysis Platform as previous procedures [29 (link)–32 (link)]. To characterize the relative activation of a given gene set, such as pathway activation, we performed QuSAGE analysis, in which gene sets, including ferroptosis, described previously, were added. Pathway analysis was used to identify the significant pathways of the marker genes and differentially expressed genes according to the kyoto encyclopedia of genes and genomes (KEGG) database. Fisher’s exact test was used to select significant pathways, and the threshold of significance was defined by the P-value and false discovery rate (FDR).

ScRNA-seq libraries were generated from each time point using the 10× Genomics Chromium Controller
Instrument (10× Genomics, Pleasanton, CA) and Chromium Single Cell 3’ Reagent Kits v1
(65,781 cells experiment) and v2 (259,155 cells experiment) according to manufacturer’s instructions. Reverse
transcription and sample indexing were performed using the C1000 Touch Thermal cycler with 96-Deep Well Reaction Module.
Briefly, the suspended cells were loaded on a Chromium controller Single-Cell Instrument to first generate single-cell Gel
Bead-In-Emulsions (GEMs). After breaking the GEMs, the barcoded cDNA was then purified and amplified. The amplified
barcoded cDNA was fragmented, A-tailed and ligated with adaptors. Finally, PCR amplification was performed to enable
sample indexing and enrichment of the 3’ RNA-Seq libraries. The final libraries were quantified using Thermo Fisher
Qubit dsDNA HS Assay kit (Q32851) and the fragment size distribution of the libraries were determined using the Agilent
2100 BioAnalyzer High Sensitivity DNA kit (5067-4626). Pooled libraries were then sequenced using Illumina Sequencing. All
samples were sequenced to an average depth of 87 million paired-end reads per sample (see Experimental Methods), with 98 bp on the first read and 10 bp on the second read. In the larger experiment, we
profiled 259,155 cells to an average depth of 46,523 reads per cell.

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.
