Sample GSM7445528 Query DataSets for GSM7445528
Status Public on Dec 01, 2023
Title KO-2, FA model (14 days), scRNAseq
Sample type SRA
Source name kidney
Organism Mus musculus
Characteristics tissue: kidney
genotype: Aoah-/-
age: 6-8 weeks old
Extracted molecule total RNA
Extraction protocol The kidney tissues were harvested after cardiac perfusion with cold PBS, then weighed, minced and incubated with 1 mg/ml type IV collagenase and 10μg/ml DNase I (both from Sigma, USA) for 40 minutes at 37℃ shaker. The digested tissue suspensions were then passed through a 40μm cell strainer and washed in PBS with 1% FBS. Erythrocytes were lysed and single cell suspension was acquired. Cells were stained with 0.4% trypan blue solution (Thermo Fisher, USA), and cell viability was was examined by Countess®II Automated Cell Counter (Thermo Fisher, USA).
Single-cell RNA sequencing libraries were prepared using the Chromium Single Cell 3′ v2 Reagent Kit (10x Genomics) according to the manufacture’s protocol. Briefly, single cells were encapsulated in oil beads with a unique molecular identifier (UMI) barcode to generate single-cellGelBeads-in-Emulsion(GEMs). Then cells were lysed and the released RNA was barcoded through reverse transcription in individual GEMs. After the reverse transcription step, cDNAs were amplified, fragmented and used for 3’ gene expression library construction.
Library strategy RNA-Seq
Library source transcriptomic single cell
Library selection cDNA
Instrument model Illumina NovaSeq 6000
Description 10x Genomics
Data processing Sequencing of the libraries was performed on a NovaSeq6000 (Illumina) using paired-end 2×150 bp sequencing. Raw sequencing data were processed following the Chromium's Cell Ranger 3.1.0 pipeline with default parameters. The raw sequencing data (FASTQs files) were aligned to the mouse genome using STAR algorithm. Then gene-barcode matrices containing the barcoded cells and gene expression counts were generated and imported into the Seurat (version 4.2.0) R toolkit for quality control and subsequent analysis. Unless specified, the default parameters were used for all functions. For quality control, cells with detected genes between 200 to 5000, mitochondrial gene percentages less than 30%, unique gene counts between 200 to 20000 were kept. In the remaining cells, gene expression matrices were log normalized for each cell by the total expression and multiplied this by a scale factor (10000 by default). Principal component analysis (PCA) for dimensional reduction was performed based on the highly variable genes (top 2000). Clusters were then visualized using the Uniform Manifold Approximation and Projection (UMAP) (ArXive-prints1802.03426,2018). Cell type identification were performed based on the expression of known cell markers.
