Genomic signature maps of different cell types can aid in the interpretation of genomic data of specimens collected during disease states. We have defined "lineage-specific" genes, as well as " activation" genes, for cellular components of the skin: keratinocytes, fibroblasts, macrophages, monocytes, T cells, immature, and mature dendritic cells (DCs). Re-analysis of a previously published gene set of psoriasis then provided a model for assessing the usefulness of these maps. We were able to ascribe over 90% of these genes to specific cell types, and there was a surprisingly large contribution from DCs. This shows the utility of such cellular gene maps.
