简介：
Overview
This article presents a method for separating and enriching components of the tumor immune and non-immune microenvironment in established subcutaneous tumors. The technique enables the analysis of tumor immune infiltrate and non-immune tumor fractions, facilitating a comprehensive characterization of the tumor immune microenvironment.
Key Study Components
Area of Science
- Oncology
- Immunology
- Cell Biology
Background
- Understanding the tumor immune microenvironment is crucial for cancer treatment.
- Profiling immune and non-immune components can reveal treatment-induced changes.
- Current methods may not effectively separate these components.
- This study introduces a novel technique for better analysis.
Purpose of Study
- To provide a method for simultaneous profiling of immune and cancer cell fractions.
- To identify changes in the tumor microenvironment following treatment.
- To enhance the understanding of tumor immunologic states.
Methods Used
- Spraying the mouse with 70% ethanol to prevent contamination.
- Surgically removing subcutaneous tumors while avoiding contaminating tissue.
- Placing tumors in RPMI 1640 medium on ice for analysis.
- Utilizing a 24-well plate for individual tumor processing.
Main Results
- The technique effectively enriches tumor immune and non-immune components.
- Allows for thorough profiling of the tumor immunologic state.
- Facilitates the identification of treatment-induced changes.
- Provides insights into the dynamics of the tumor microenvironment.
Conclusions
- This method is a significant advancement in tumor microenvironment analysis.
- It can help answer key questions in immune oncology.
- Future studies can build on this technique for deeper insights.
