This article was originally published with an error in figure 3, in which part b was a duplication of part a. The corrected figure is shown below and has been corrected in the article itself.
In situ hybridisation detection of CNR1 and CNR2 gene transcripts in human airway epithelial cells. In situ hybridisation of a) CNR1 and b) CNR2 in three patient donors representative of n=10. Serial sections of each of the three cases were stained for CNR1 and CNR2. Low magnification images are in the centre of a and b, with high-powered magnification regions of interest on either side highlighted by black boxes. Pink arrows correspond to positive puncta representative of mRNA transcript.
