Human cells were resuspended in PBS with 0.4% Bovine Serum Albumin (BSA) buffer at the concentration of 1000 cells/µL. About 20,000 cells were loaded onto a ChromiumTM X instrument (10x Genomics) according to manufacturer's instructions. The scRNAseq libraries were processed using Chromium GEM-X Single Cell 5' Kit v3 (10x Genomics).
