E-cadherin-mCFP mice have monomeric cyan fluorescent protein (mCFP) fused to the endogenous cadherin 1 protein (Cdh1). These mice are useful for imaging studies in all types of epithelia that express E-cadherin, including crypt cells of the small intestine.

Targeted (Reporter, Null/Knockout) | Cdh1 | cadherin 1 |
These Cdh1 (cadherin 1; also called E-cadherin) targeted mutant mice express a monomeric cyan fluorescent protein (mCFP) fused to the endogenous E-cadherin protein. The cDNA of mCFP is targeted to replace the STOP codon in exon 16 of Cdh1, preserving the native 3' UTR. This mouse line enables the visualization of all epithelial structures within the mouse. Three dimensional (3D) crypt architecture in the small intestine has been visualized to depths of 125 um. Appropriate expression has also been seen in hair follicles, skin, lung, stomach and colon. The E-cadherin-mCFP fusion protein correctly localizes in the plasma membrane of cells. The fusion strategy results in one extra valine as a linker between E-cadherin and mCFP. These mice are likely to be useful for imaging studies in all types of epithelia that express E-cadherin.
Monomeric cyan fluorescent protein (mCFP) and a loxP-flanked neomycin cassette were targeted to exon 16 (encoding the endogenous STOP codon) to maintain normal expression levels and patterns. The 129P2/OlaHsd-derived IB10/E14IB10 embryonic stem cell line was used to create the mutation. Resultant mice were crossed with a PGK-cre mouse of unknown genetic background to excise the neomycin cassette. This strain was backcrossed to C57BL/6 for 4-6 generations by the donating laboratory.

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
