Abstrakt: Deletion of gene expression in the target tissues and cells is an effective strategy for elucidating the physiological functions of the protein of interest. For tissue-specific and/or inducible gene deletion, the Cre-loxP system has been widely used in various model organisms including medaka (Oryzias latipes). The epithelium is the key tissue, locating at the outermost area and playing a role in barrier to external stimuli. Despite a large genetic toolbox developed in medaka, there is no available Cre-driver line that works in an epithelium-specific manner. Here, we established epithelium-specific Cre-driver lines in medaka using a homology-directed repair mediated knock-in approach with CRISPR/Cas9, targeting each of periplakin and keratin genes. We show that Cre-recombinase is expressed exclusively in the epithelium in the knock-in lines and that it efficiently and specifically induces recombination in the tissues. These Cre-driver lines are useful for studying the functions of proteins expressed in the epithelium.
