Unique transcriptome of LCs distinguishes them from DCs and macrophages. (A) LCs share characteristics with macrophages (yolk sac origin, tissue residence) and DCs (priming T lymphocytes, migration to the lymph nodes). (B) Hierarchical clustering analysis of GSE60317 dataset. Samples include LCs (yellow box), CD14+ dermal DCs (orange box), and cutaneous macrophages (blue box) total RNA expression data. Data obtained from GEO (Illumina Human WG-6 v3.0) were log transformed and normalized before using all probes for hierarchical clustering analysis (hclust package, R: Euclidean distance and complete clustering). The cluster analysis revealed LCs to be transcriptionally distinct from both dermal CD14+ dendritic cells and macrophages.
