Organism: Homo sapiens Tissue: Adrenal cortex Samples: 20 adrenocortical carcinoma (ACC) samples Experimental design: After frozen tissue dissociation, nuclei were incubated with a Alexa Fluor® 647 anti-Nuclear Pore Complex Proteins Antibody Mab414 (BioLegend), then sorted using a FACSAria III (BD Biosciences) with the 85 μm nozzle and the BD FACSDIVA software. Sorted nuclei were immediately processed on a Chromium Controller (10x Genomics). Library preparation was performed using the Chromium Single-Cell v3 3′ Gel Bead, Chip and Library Kits (10x Genomics) according to the manufacturer’s protocol. Librairies were sequenced on a NextSeq 500 platform (Illumina) with paired-end sequencing. Data processing: The demultiplexing, barcoded processing and gene counting were performed with the Cell Ranger software v3.1.0. File format and content: The dataset includes the filtered expression matrices generated by Cell Ranger for individual samples. Each filtered expression matrix is saved as 3 files (***_barcodes.tsv.gz, ***_features.tsv.gz, and ***_matrix.mtx.gz) where *** is replaced by the sample name.
