| Outline of Final Research Achievements |
Keratocan-IRES2-nls-Cre and Keratocan-IRES2-CreERT2 knock-in mouse lines were newly developed by gene targeting technique using C57BL/6-derived ES cells for keratocyte specific Cre-lox P recombination. These mice were mated with ROSA26mT/mG or ROSA26LacZ to investigate temporal and spatial Cre recombinase expression pattern. In Keratocan-IRES2-nls-Cre/ ROSA26LacZ embryo, Cre recombinase expression was observed in periocular mesenchymal cells. After birth, Cre recombinase expression were observed in keratocytes and hippocampal CA1 pyramidal cells. In keratocytes of Keratocan-IRES2-CreERT2/ROSA26mT/mG mice, Cre-lox P recombination were observed after tamoxifen induction. These mouse lines will become useful model for keratocyte stem cell biology.
