Abstract:
One of the key challenges to improved testing of new experimental therapeutics in renal cell carcinoma (RCC) is the development of models that faithfully recapitulate early- and late-stage metastatic disease progression. Typical tumor implantation models utilize ectopic or orthotopic primary tumor implantation, but few include systemic spontaneous metastatic disease that mimics the clinical setting. This protocol describes the key steps to develop RCC disease progression stages similar to patients. First, it uses a highly metastatic mouse tumor cell line in a syngeneic model to show orthotopic tumor cell implantation. Methods include superficial and internal implantation into the sub-capsular space with cells combined with matrigel to prevent leakage and early spread. Next it describes the procedures for excision of tumor-bearing kidney (nephrectomy), with critical pre- and post- surgical mouse care. Finally, it outlines the steps necessary to monitor and assess micro-and macro-metastatic disease progression, including bioluminescent imaging as well provides a detailed visual necropsy guide to score systemic disease distribution. The goal of this protocol description is to facilitate the widespread use of clinically relevant metastatic RCC models to improve the predictive value of future therapeutic testing.
Insights
Developing accurate models for renal cell carcinoma (RCC) metastasis is crucial for testing new therapies. This protocol details creating clinically relevant metastatic RCC models in mice to improve therapeutic testing and predict treatment success.
Area of Science:
- Oncology
- Translational Research
- Animal Models
Background:
- Accurate preclinical models are essential for advancing renal cell carcinoma (RCC) therapeutics.
- Existing models often fail to replicate the spontaneous metastatic progression seen in clinical RCC.
- There is a critical need for models that recapitulate both early- and late-stage metastatic disease.
Purpose of the Study:
- To describe a protocol for developing clinically relevant metastatic RCC models in mice.
- To facilitate the creation of models that mimic spontaneous systemic metastatic disease progression.
- To enhance the predictive value of future therapeutic testing in RCC.
Main Methods:
- Utilized a highly metastatic mouse tumor cell line in a syngeneic model for orthotopic implantation.
- Detailed procedures for kidney tumor cell implantation (sub-capsular space) with matrigel.
- Included nephrectomy, critical pre- and post-surgical care, and monitoring of metastatic progression via bioluminescent imaging and necropsy.
Main Results:
- Successfully established a protocol for generating metastatic RCC models.
- Demonstrated methods for orthotopic implantation, surgical intervention, and disease monitoring.
- Provided a detailed necropsy guide for scoring systemic disease distribution.
Conclusions:
- This protocol enables the development of RCC models that faithfully recapitulate metastatic disease.
- Widespread adoption of these models will improve the reliability of preclinical therapeutic testing.
- Facilitates better prediction of treatment efficacy for experimental therapeutics in RCC.
