Library selection cDNA
Instrument model Illumina NovaSeq 6000
Data processing Raw sequencing data for each sample were converted to matrices of expression using cellranger (version 3.1.0, 10x Genomics), for GEX-seq data using cellranger count parameter and for VDJ-seq data using cellragner vdj parameter
doublet removal with Scrublet (version 0.2.3)
removal of ambient mRNA with SoupX (version 1.3.6)
normalization, logtransform, variable genes calling with Scanpy (version 1.4.1)
Integrate samples with bbknn
cells cluster with leiden
different gene analysis with Seurat (version 3.1.1)
Genome_build: GRCh38 human reference genome (official Cell Ranger reference, version 3.0.0)
