Cell type specific gene expression. Identification of cell type specific gene expression was performed by applying stringent filter on the gene expression data (for details see Materials and Methods). Some of the results are shown. The databases BioGPS (http://www.BioGPS.org) and the tool Genevestigator (http://www.genevestigator.com) were drawn upon to compare results of the present study with third party data. The present dataset shows that cell separation provides known and novel information on gene expression. Expression patterns of C10orf11 (CD14+ cells), CD19 (CD19+ cells), and MLC1 (CD56+ cells) was largely confirmed. No information was available for CD15+ cells in the external databases, and there was no information on TRAV17, which was highly expressed in T cell subtypes.
