To identify TRPV6 expression in the whole mouse with a cellular resolution we took advantage of TRPV6-IRES-Cre knock-in mice crossed with the enhanced ROSA26-τGFP reporter line. In the resulting TRPV6-IC/eR26-τGFP animals, TRPV6-expressing cells are labeled with τGFP. Data were collected from organs prepared from fixed experimental adult and juvenile TRPV6-IC/eR26τGFP and Cre-negative eR26-τGFP control animals of both sexes. Organ cryosections from each age and sex were stained for GFP and imaged with a slide scanner. Here, we describe reporter gene expression in a large number of tissues. We also document the absence of τGFP signal in the corresponding Cre-negative control tissues, including controls for the TRPV6 expression data described in [1]. The data reported here and in [1] constitute the TRPV6 expression atlas for the mouse. Our data offer a wealth of information to enable investigation of the functional role of TRPV6 channels in different tissues.
