Polycystic Kidney Disease – ADPKD Mouse Model (Pkd1 KO)
Use the gold-standard research ADPKD mouse model to test the efficacy of your novel therapeutics for Polycystic Kidney Disease
ADPKD Mouse Model Key Characteristics
Autosomal dominant polycystic kidney disease (ADPKD) is characterized by the development of renal fluid-filled cysts, eventually leading to kidney failure. With a prevalence of 4 in 10.000, ADPKD is a relatively common genetic disorder. Mutations in the Pkd1 gene are associated with approximately 85% of ADPKD cases.
To support the preclinical development of new drugs and therapies for ADPKD, InnoSer offers a well-established, conditional, renal-specific Pkd1 knock-out (KO) ADPKD mouse model.Â
✓ The ADPKD mouse model is an inducible, kidney-specific Cre (lox,lox)-Pkd1 knock-out (KO) model.Â
✓ Conditional KO of the Pkd1 gene at specific time points results in three different models with different stages of disease progression.
✓ ADPKD mice show age-dependent, reproducible cyst formation and epithelial cell proliferation, similar to ADPKD patients.Â
✓ InnoSer offers multiple validated positive controls in the ADPKD mouse model.Â
Take advantage of InnoSer’s expertise, flexibility and collaborative approach for your research. We support our clients in identifying new drugs or applications, characterizing their pharmacological properties, and conducting safety and efficacy testing with state-of-the-art readout capabilities and histopathological analysis.Â
InnoSer’s neurology expert team possesses relevant experience in working with multiple therapy types ranging from small molecules, biologics (antibodies, peptides, enzymes), and gene therapy (viral vectors – e.g.. AAVs).Â
ADPKD Mouse Model Options
InnoSer offers different ADPKD mouse models by specifically timed Tamoxifen-induced Pkd1 knockout. There are three models available depending on which post-natal (P) day Tamoxifen is administered:Â
The P10 model is widely used as a first screening platform as it offers quick and robust results with renal cyst formation, while the P18 and P40 models show a slower progression even closer to clinical phenotypes.Â
For all your nephrology projects, we support custom in vivo models for kidney injury and toxicological studies.Â
Model | Cyst characteristics |
P10 | Quick progression of cyst formation in the distal segment of the nephron |
P18 | Slow progression with cysts in all segments of the nephron |
P40 | Slow and reproducible cyst formation in the proximal part of the nephron |
Timelines using ADPKD Mouse Model
Conditional Pkd1 knockout at different time points (P10, P18, P40) allows the establishment of multiple mouse models, with different disease progressions and phenotypes to meet your specific requirements in terms of study duration, outcome measures and clinical translatability.Â
ADPKD Mouse Model Sample Data
ADPKD mice show a progressive decrease in kidney function marked by a decrease in GFR.
Over time, we observe a significant decrease in the GFR of the ADPKD group in comparison to the healthy control group, confirming the loss of renal function in PKD mice and the suitability of this method in efficacy studies in this preclinical mouse model of ADPKD.

Cystic index enables the end-stage efficacy assessment of your test compound on renal health.
(A) Cystic index in the P10 model is significantly lower in the Everolimus and test compound A groups compared to the vehicle control group (mean ± SEM; one-way ANOVA). (B) Cystic Index in the P18 model is significantly lower in the Tolvaptan and test compound B groups compared to the vehicle control group (mean ± SEM; one-way ANOVA). Read more about the difference between the P10 and P18 models here.Â
Salsalate treatment (0.25% in food) reduces cystic index (%) in the ADPKD mouse model.
(A) Compared to Pkd1 KO mice administered with vehicle (food pellets), Salsalate-administered Pkd1 KO mice show a significant decrease in cystic index (P=0.0001), indicative of improvement of the pathophysiological kidney disease. (B) Representative histological image of kidney obtained from healthy mouse. (C) Representative histological image of kidney obtained from Pkd1 KO vehicle-treated mouse. (D) Representative histological image of kidney obtained from Pkd1 KO Salsalate-treated animal. In comparison to vehicle-treated animals, Salsalate-treated mouse have smaller cysts with lower distribution (arrows).

Frequently Asked Questions
What is the mouse model of ADPKD?
The mouse model of ADPKD is a genetically engineered research tool used to study Autosomal Dominant Polycystic Kidney Disease (ADPKD). InnoSer’s inducible kidney-specific Cre(lox,lox)–Pkd1 knockout (KO) mouse model is the gold standard model for evaluating the efficacy of novel therapeutics for ADPKD in preclinical research. Discover how this model has been used in research. View the publication list here.Â
What positive controls are used in the ADPKD mouse model?
Positive controls in the ADPKD mouse models include known compounds that predictably influence cyst formation. Including positive controls in a study is essential to establish a comparison for evaluating the efficacy of novel therapeutic compounds. At InnoSer, we have validated a multitude of positive controls: – mTOR inhibitors (Everolimus, Rapamycin) – Vasopressin receptor antagonists (Mozavaptan, Tolvaptan; only approved ADPKD treatment), – AMPK activators (Salsalate; view validation data in our previous blog posts here and here). The selection of a positive control depends on your test item’s mechanism of action. For example, Salsalate may be used as comparator for therapies targeting AMPK-involved pathways. Contact our team to identify the right positive controls for your ADPKD study.
How do your models replicate the cyst formation seen in ADPKD patients?
InnoSer’s Pkd1 knockout mouse models of ADPKD highlight different aspects of cyst formation observed in human ADPKD patients by conditionally disrupting the Pkd1 gene expression. The inducible feature of this model allows a disruption of Pkd1 gene expression at specifically chosen time points, both in juvenile and adult mice. This not only allows a well-controlled evaluation of ADPKD pathogenesis, but also the creation of different ADPKD progression models (P10, P18, and P40), thanks to the characteristic age-dependent cyst formation observed in these animals. This allows the evaluation of different aspects of disease progression and how they can be influenced by a therapeutic test item depending on the mode of action. The different models all replicate hallmark features of human ADPKD, including progressive kidney enlargement, cyst formation, and impaired kidney function. Learn more about our P10, P18, and P40 models in our blog post here.
Are InnoSer's ADPKD mice readily available for studies?
Yes, InnoSer maintains a continuous stock of ADPKD mouse colonies, meaning that they do not have to be sourced from other laboratories, supporting quick study starts, whilst helping you avoid high costs associated with animal purchases as well as timeline delays due to quarantining periods. At InnoSer, we can accommodate studies with up to 8 treatment groups and handle >100 animals per study, ensuring flexibility for even the most complex study designs.
