Analysis of human trunk skin using scRNAseq (complement to Fig. 2 ). (A) UMAP of scRNAseq data collected from human trunk skin. Clusters consist of 17 keratinocyte clusters and 3 clusters matching non-keratinocyte signature genes (melanocytes, cl. 7 and 18; immune cells, cl. 17). (B and C) Feature map plotting expression levels of (B) KRT14 or (C) KRT10 in the human trunk UMAP. (D) Expression of KRT14 (green) and KRT10 (red) in the human trunk dataset, as described in Fig. 2 C. (E) Feature map of KRT15 expression levels in human trunk dataset presented as UMAP form. (F and G) Expression of the S-phase composite score relative to (F) KRT15 and (G) KRT14 levels across keratinocytes in human trunk epidermis. (H) Expression of G2/M composite score relative to KRT10 levels across keratinocytes in human trunk epidermis.
