简介：
Overview
This protocol describes a method for the detailed evaluation of leukocyte subsets within the tumor microenvironment in a mouse tumor model. Chemerin-expressing B16 melanoma cells were implanted subcutaneously into syngeneic mice, and cells from the tumor microenvironment were analyzed by flow cytometry.
Key Study Components
Area of Science
- Neuroscience
- Immunology
- Oncology
Background
- Understanding the tumor microenvironment is crucial for cancer research.
- Leukocyte subsets play significant roles in tumor progression and immune response.
