TRiCK (TRiple Coloured germ layer Knock-in) mouse
|TRiCK (TRiple Coloured germ layer Knock-in) mouse is a strain that can label all three germ layers that make up the early embryo. This both independent and simultaneous labeling system is achieved by combination with self-cleaving 2A peptides, site-specific recombinases and fluorescent proteins. In brief, TRiCK mouse can be produced by crossing two strains. One is a reporter strain that emits a fluorescent signal (Venus/mCherry/mCerulean) upon induction of expression of site-specific recombinase (Cre/Dre/phiC31o), under the control of both endogenous ROSA26 promoter and exogenous CAG promoter (RBRC10966). The other is a labeling strain that expresses Cre under the control of neuroectodermal marker Sox1, Dre under the control of mesodermal marker T (Brachyury), and pChiC31o under the control of endodermal marker Sox17 (RBRC10967). The TRiCK system has been shown to function not only during early embryonic development but also in adult tissues. In addition, tissue fixation and tissue clearing methods optimized for the analysis of TRiCK mice have been reported. Therefore, the TRiCK mouse is a useful strain for elucidating developmental and regenerative phenomena and pathogenesis.|
