| Extraction protocol |
To isolate the nuclei, the cells were transferred to a 1.5 ml Eppendorf tube and centrifuged at 200 g for 5 mins. The supernatant was discarded and 1 ml of 1x PBS was added. The cells were then centrifuged for 5 minutes at 200 g and the supernatant discarded. Cells were treated for 10 minutes on ice in 125 µl buffer (10 mM HEPES (pH 7.9), 10 mM KCl, 1.5 mM MgCl2, 0.34 M sucrose, 10% glycerol, 1mM DTT) supplemented with 0.1 % Triton X-100 and a freshly added cOmplete mini tablet (Roche). Afterwards, the samples were centrifuged at 1300 g for 5 minutes and the supernatant was discarded. To freeze the nuclei, the samples were resuspended in 1 ml buffer containing 700 µl glycerol and slowly cooled down to -80°C. Prior to library preparation, samples were thawed on ice, filled up with buffer to a total volume of 1.5 ml, and centrifuged for 3 min at 1300 g. Next, the supernatant was discarded without fully exposing the pellet. Samples were subsequently resuspended in 1 ml of buffer, centrifuged for 3 minutes at 1300 g and 4°C. The supernatant was discarded, and the nuclei were resuspended in 100 µl buffer and stored on ice. Subsequently, they were processed with the 10X Multiome Gene Expression + ATAC kit.
Approximately 10,000 nuclei per sample were loaded into the Chromium Controller system, and libraries were subsequently prepared using the Chromium Next GEM Single Cell Multiome ATAC + Gene Expression Reagent Kit (10X Genomics), following the manufacturer’s instructions. Libraries were sequenced on a NovaSeq 6000 device (Illumina) using paired-end (50 + 100 bp) settings for 150 cycles for the scRNA-seq, and paired-end (50+100 bp) for 150 cycles for the scATAC-seq.
