Description ApoE mice feed with ND
Data processing UMI-tools is used for the end to end processing of scRNA-Seq data
Identified cell barcodes and UMI in the read sequence, which are then extracted from Read 1 and added to Read 2 read name. STAR,was used to map extracted reads from Read 2 to the reference mouse genome build 38 (GRCm38), followed by assigning reads to genes using featureCounts tool from the subread package (version 1.6.0). Quantification was performed using UMI-tools count function to find the number of unique UMIs mapping to each gene (GENCODE mouse annotation, release M15).
Count data was filtered by: removing cells for which UMI count was less than 3,000 or total number of detected genes was less than 1,500; removing genes that were not expressed in less than or equal to 5% of the remaining cells in at least one sample
ApoE and TGFβR2 UMI counts were removed from the processed data matrix
Genome_build: GRCm38, version M15 (Ensembl 90)
Supplementary_files_format_and_content: CSV files include raw and TMM values for all samples
