Single cell RNA-sequencing of innate lymphoid cells isolated from mouse skin layers

Purpose: Determine the layer-specific indentities and heterogeneity of innate lymphoid cells in the skin by single cell transcriptomic analysis Methods: Innate lymphoid cells were sorted from epidermis, dermis and subcutis of adult B6 mice and subjected to droplet based single-cell captureing and RNA isolation and library preparation. Results: 3,431, 3,356 and 1,061 innate lymphoid cells from epidermis, dermis, and subcutis were analyzed. Unsupervised clustering of the combined data set performed in Seurat identified 6 distinct ILC clusters. Conclusions: This study reveals skin layer-specific transcriptomic signature of innate lymphoid cells Transcriptome profiles of skin innate lymphoid cells were generated by droplet-based single cell RNA-seq
