Erratum for the Research Article “Cystic fibrosis alters the structure of the olfactory epithelium and the expression of olfactory receptors affecting odor perception” by I. Caballero et al .

The original version of the Research Article “Cystic fibrosis alters the structure of the olfactory epithelium and the expression of olfactory receptors affecting odor perception” by I. Caballero et al. included errors in their source data for Figs. 1 and 2. During figure preparation, a subset of the control group samples was inadvertently duplicated. The authors removed the duplicated cells from the source data, resulting in changes to the main text, Figs. 1 (C to F) and 2 (A to D), and their captions.
