Fgf18 Knockout mouse models
Fgf18, ortholog of human FGF18, encodes a secreted FGF8 subfamily ligand that signals principally through FGFR3c and FGFR4, with additional FGFR1c and FGFR2c engagement, and functions as a positive regulator of chondrocyte proliferation, matrix production, and growth plate hypertrophic transition while simultaneously restraining osteoblast differentiation timing, thereby coordinating endochondral ossification and cranial suture closure. It is the basis of the intra-articular cartilage anabolic agent sprifermin, which makes species-matched receptor engagement a practical concern. Germline nulls die in the perinatal period with delayed ossification, expanded proliferative zones, and craniosynostosis-like suture abnormalities, so conditional floxed alleles combined with Col2a1-Cre, Prrx1-Cre, or Sp7-Cre are the appropriate tool for postnatal joint and skeletal work. Overlapping activity from Fgf9 at the same c-isoform receptors means compound conditionals are advisable when the endpoint is complete growth plate FGF input. Align allele class to readout: humanized knockins for sprifermin-type pharmacology, conditional deletion for cartilage homeostasis and osteoarthritis progression.
Fgf18 null animals are straightforward to genotype and phenotype when survival is acceptable. They remain a standard background for pharmacology, biomarker, and rescue studies.

Why this approach
A conventional knockout answers whether the gene is required broadly. When your target tissue is the organ of interest, a global null can still be informative if viability is acceptable and you want the simplest genotype. If the null is harsh, a floxed allele with a regional Cre is the safer long term platform.

FAQ
What Fgf18 Knockout mouse models are available?
When Fgf18 Knockout lines are in catalog, we ship from inventory. If your configuration is not listed, we design the allele to order. Common paths include conditional knockout, constitutive knockout, humanized, knockin, and transgenic options, with documented germline transmission and United States QC.
Is Fgf18 knockout embryonic lethal in mice?
It depends on background and allele design. Some Fgf18 germline knockouts are viable. Others need conditional alleles or mixed backgrounds. We review publications and our own experience, then recommend floxed versus null before you commit.
Which Cre driver is best for experiments?
Driver choice depends on onset timing, recombination efficiency, and known leak. We map your organ and cell type to a short list of proven Cre lines, then talk through reporter crosses and controls. We favor drivers with strong community validation for your tissue.
Do you ship live Fgf18 animals?
When catalog lines are live, we ship with health certificates and QC documentation. If your exact combo is not listed, we quote a generation project with cryo or live dispatch depending on cohort timing and geography.
How do I request a quote for Fgf18?
Use the catalog inquire buttons or the request quote form. Include your allele goal, Cre plan if any, strain background, and cohort size. A PhD led team responds with pricing, milestones, and the fastest path to experimental animals.
