We present an optimized dissociation protocol for preparing high-quality skin cell suspensions for in-depth single-cell RNA-sequencing (scRNA-seq) analysis of fresh and cultured human skin.Our protocol enabled the isolation of a consistently high number of highly viable skin cells from equi-jec 6 small freshly dissociated punch skin biopsies, which we use for scRNA-seq studies.We recapitulated not only the main cell populations of existing single-cell skin atlases, but also identified rare cell populations, such as mast cells.Furthermore, we effectively isolated highly viable single cells from ex vivo cultured skin biopsy fragments and generated a global single-cell map of the explanted human skin.The quality metrics of the generated scRNA-seq datasets were comparable between freshly dissociated and cultured skin.

Overall, by enabling efficient cell isolation and comprehensive cell mapping, our skin dissociation-scRNA-seq workflow can greatly facilitate scRNA-seq discoveries rosy teacup dogwood across diverse human skin pathologies and ex vivo skin explant experimentations.
