Overview

Also Known As: CX3CR1-GFP

CX3CR1-GFP mice express EGFP in monocytes, dendritic cells, NK cells, and brain microglia under control of the endogenous Cx3cr1 locus. They may be useful in studies of leukocyte migration and trafficking, as well as for transplantation studies.

Detailed Description

Mice that are homozygous for the CX3CR1-GFP targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. RT-PCR analysis of lymphoid tissue from homozygotes detects mutant gene product (mRNA) and no wild type gene product (mRNA). Flow cytometric analysis of peripheral blood cells identified a subset of green fluorescent cells not observed in wildtype mice. Enhanced Green Fluorescent Protein (EGFP), but not the endogenous gene, is expressed in monocytes, dendritic cells, NK cells, and brain microglia - mimicking endogenous gene expression. The same subset of peripheral blood cells isolated from heterozygote mice express detectable levels of EGFP. These CX3CR1-GFP mutant mice may be useful in studies of leukocyte migration and trafficking, as well as for transplantation studies.

Of note, CX3CR1-GFP mice are also available harboring with the CD45.1 (Ly5.1 or Ptprc^a) allele, which is atypical for the C57BL/6 congenic background (see Stock No. 008451).

When compared with GFP expression in monocytes in C57BL/6-Tg(CD68-EGFP)1Drg/J mice (Stock No. 026827) using a sterile zymosan peritonitis model, CD68-GFP monocytes retain high-level GFP expression as they differentiate to become mature macrophages, while, CX₃CR1^GFP monocytes downregulate GFP expression on differentiation into macrophages.

Development

A targeting vector containing an Enhanced Green Fluorescent Protein (EGFP, Clontech) cDNA sequence, loxP-flanked neomycin resistance gene, herpes simplex virus thymidine kinase gene, and SV40 polyadenylation site sequence was used to disrupt the first 390 bp of exon 2. The construct was electroporated into 129P2/OlaHsd derived E14.1 embryonic stem (ES) cells which were transiently transfected with a Cre recombinase vector to remove the selection cassette. ES cells that had successfully undergone Cre-mediated recombination (removing the loxP-flanked neo cassette and leaving a single loxP site downstream of EGFP) were injected into recipient blastocysts. The donating investigator reported that resulting chimeric animals were backcrossed to C57BL/6 (see SNP note below) for ten generations before being made homozygous. During the backcross, mice were likely bred to a B6.CD45.1 congenic strain (harboring the CD45.1 (Ly5.1 or Ptprc^a) allele rather than the CD45.2 (Ly5.2 or Ptprc^b) allele normally present in C57BL/6 mice). These mice, however, were bred such that they still harbor the expected CD45.2 (Ly5.2 or Ptprc^b) allele normally present in C57BL/6 mice.

In 2011, a 32 SNP (single nucleotide polymorphism) panel analysis, with 27 markers covering all 19 chromosomes and the X chromosome, as well as 5 markers that distinguish between the C57BL/6J and C57BL/6N substrains, was performed on the rederived living colony at The Jackson Laboratory Repository. While the 27 markers throughout the genome suggested a C57BL/6 genetic background, 2 of 5 markers that determine C57BL/6J from C57BL/6N were found to be segregating. These data suggest the mice sent to The Jackson Laboratory Repository were on a C57BL/6N genetic background or a mixed C57BL/6J;C57BL/6N genetic background. In 2013, the same SNP panel analysis showed 4 of 5 markers that determine C57BL/6J from C57BL/6N were segregating. The living colony is on a mixed C57BL/6J;C57BL/6N genetic background.

Strain of Origin	129P2/OlaHsd
Chromosome	9
Molecular Note	The endogenous locus was disrupted by the insertion of sequence encoding green fluourescent protein (GFP), replacing the first 390 bp of the coding exon (exon 2). The deleted region encoded an amino-terminal portion of the protein that is crucial for interaction with endogenous ligand, Cx3cl1. A floxed neo gene included in the targeting vector for selection was excised prior to germline transmission, leaving a single loxP site downstream of the GFP sequence. RT-PCR and flow cytometry indicated an absence of endogenous protein and the presence GFP expression in homozygous mutant mice.

We will fulfill your order by providing at least two carriers for each strain ordered. The total number, sex, and genotypes provided will vary, although typically 8 or more animals are provided. Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.

The Jackson Laboratory's Genotype Promise

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.
