Expression correlation of olfactory and other tissues. Pearson correlation of human olfactory epithelium and a selected set of control tissues. Correlation was calculated for each tissue pair based on vectors with the logarithmic FPKM value of 16,288 genes. Correlation values are on average 0.91 ± 0.0 among the olfactory epithelium tissues and 0.74 ± 0.1 between the olfactory epithelium tissues to the controls. Tissue abbreviations: OE, human olfactory epithelium; rsp, respiratory; brn, brain; lvr, liver; kdn, kidney; lng, lung
