library_construction_protocol: 6 mm punch skin biopsy tissues from 13 psoriasis patients and 5 healthy volunteers were bisected, and one of the two bisected skin tissues was incubated in culture medium for harvesting emigrating cells. Harvested skin tissue was immediately placed in 0.2% Dispase II (Sigma-Aldrich) and incubated in a humidified incubator at 37oC and 10% CO2 for 3 hours. Then, epidermis and dermis were separated with forceps and sliced into small pieces with #10 blade scalpels. Epidermis and dermis were separately cultured in RPMI-1640 medium with L-glutamine (Cytiva) supplemented with 10% human albumin serum (Sigma-Aldrich) and without any enzyme or antibiotic agent in a humidified incubator at 37oC and 5% CO2. Nonplastic adherent cells that had emigrated out of epidermis and dermis were harvested after 48 hours. The harvested cells from epidermis and dermis were combined and filtered through a 40-µm cell strainer (Corning) and stored on ice. The 10x Genomics Chromium Single Cell 3′ Reagents Kit user guide (https://support.10xgenomics.com/single-cell-gene-expression/library-prep) was used to prepare the single cell suspension. The appropriate volume of each sample was diluted to recover 5,000-10,000 cells. Subsequently, the single cell suspension, Gel Beads and oils were added to the 10x Genomics single-cell chip. After droplet generation, samples were transferred into PCR tubes and we performed reverse transcription using a ProFlex PCR Thermocycler System (Applied Biosystems). After reverse transcription, cDNA was recovered using a recovery agent, provided by 10x Genomics, followed by silane DynaBead clean-up as outlined in the user guide.
