These Ptchflox mutant mice possess a loxP sites flanking exons 8-9 of the targeted gene. This strain may be useful for studying Hedgehog/Patched signaling, cell-fate determination during embryogenesis, cell growth and differentiation, and development of T- and B-lymphoid lineages, hematopoietic stem cell diversification.

These Ptchflox mutant mice possess loxP sites flanking exons 8-9 of the targeted gene. Mice that are homozygous for this allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. When these mutant mice are bred to mice that express Cre recombinase, resulting offspring will have exons 8-9 deleted in the cre-expressing tissue. The donating investigator reports that the frt-flanked neo cassette is still present downstream of the floxed exon that the presence of neo does not convey any abnormalities. This strain may be useful for studying Hedgehog/Patched signaling, cell-fate determination during embryogenesis, cell growth and differentiation, and development of T- and B-lymphoid lineages, hematopoietic stem cell diversification.
A targeting vector was designed to insert a loxP site upstream of exon 7, and a second loxP site followed by a frt-flanked neomycin resistance (neo) cassette just downstream of exon 9 of the Patched (Ptch) targeted gene. The construct was electroporated into (129X1/SvJ x 129S1/Sv)F1-Kitl+-derived R1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts and resulting chimeric males were bred to C57BL/6 females. Mice heterozygous for this Ptchflox allele were bred together to generate homozygotes. This line was backcrossed to C57BL/6N for 10 generations prior to arrival at The Jackson Laboratory. Upon arrival, mice were bred to C57BL/6NJ inbred mice (Stock No. 005304) for at least one generation to establish the colony.

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.
