library_construction_protocol: the keloid tissue was washed in phosphate-buffered saline (PBS). Excised keloids were immersed in physiological saline and immediately transferred to the lab. After sample was minced into small pieces with scalpel in a petri-dish, prepared dissociation solution (2 mg/ml Liberase TL in PBS, Sigma Aldrich) was used to digest at 37ºC for 60 min. The debris were filtered out with a 70-μm cell strainer (#352340, Corning). The remaining tissue were transferred into dissociation solution containing 0.25% Trypsin for a second round of dissociation. Subsequently, the live cells were resuspended in PBS-0.04% bovine serum albumin. Cells were pelleted by centrifuging at 500 x g for 5min. To generate single-cell gel bead emulsions, suspensions of skin cells were immediately injected into the Chromium Controller (10x Genomics) targeting 9,000 cells, respectively. Following the manufacturer's protocols, the Chromium Single Cell 3' Reagent V2 Chemistry Kit(10x Genomics) was used to construct single cell libraries. Then, prepared libraries were sequenced on NovaSeq 6000 Sequencing System (Illumina, USA) or Illumina NextSeq 550 System targeting 50,000 raw reads per cell.
