Sample GSM6428697 Query DataSets for GSM6428697
Status Public on Apr 18, 2024
Title All samples
Sample type SRA
Source name Lung
Organism Mus musculus
Characteristics tissue: Lung
time: day 0, 7, 14, 21
cell type: Mesenchymal cells
genotype: Scube-CreER +/+, Rosa26 tdTomato/tdTomato
treatment: non-bleomycin-treated or bleomycin treated
Treatment protocol Sucbe2-CreER/Rosa26-tdTomato double homozygous mice were treated with 2mg tamoxifen/day for two weeks. Two weeks after the last tamoxifen injection, mice were treated with 2.5U/kg bleomycin by oropharyngeal aspiration, and harvested on day 0 (non-bleomycin treated), 7, 14, and 21
Extracted molecule total RNA
Extraction protocol Lungs were harvested and dissociated by collagenase and dispase at 37C for 60 min. Mesenchymal cells (CD31-, CD45-, EpCAM-, Ter119-) were enriched by magnetic negative selection and FACS.
Three biological replicates at each time point were multiplexed by 10x Genomics 3’ CellPlex Kit. Tag assignment was as follows; day 0 (301, 302, 303), day 7 (304, 305, 306), day 14 (307, 308, 309), and day 21 (310, 311, 312). All 12 samples were pooled and 30,000 cells / lane were loaded onto 4 lanes of Chromium Next GEM Chip (10x Genomics). Chromium Single Cell 3’ v3.1 (10x Genomics) reagents were used for library preparation
Library strategy RNA-Seq
Library source transcriptomic single cell
Library selection cDNA
Instrument model Illumina NovaSeq 6000
Data processing Fastq files were uploaded to 10x Genomics cloud analysis website ( and reads were aligned to a custom reference of mouse genome mm10 with tdTomato-WPRE-polyA transcript sequence.
The data were demultiplexed and multiplets identified by the presence of multiple oligonucleotide tags were removed using 10x Genomics cloud analysis function with default parameters.
Raw count matrices were imported to the R package Seurat v4.1.0 and cells with fewer than 200 detected genes, larger than 7500 detected genes, or larger than 15% percent mitochondria genes were excluded.
We used DoubletFinder package for individual samples to remove doublets that were not detected upon alignment using estimated multiple rate 2%.
We then merged all the sample objects by RunFastMNN
Assembly: mm10 with tdTomato-WPRE-polyA
Supplementary files format and content: rds file: Seurat v4 object after filtering, merging, and clustring
Supplementary files format and content: mtx, tsv, csv files: raw count, barcode, genes, and meta data before any filtering
