简介：
Overview
This study presents the generation of an orthotopic rat model of pleural malignant mesothelioma through the implantation of II-45 mesothelioma cells into the pleural cavity of immune competent rats. Additionally, a flow cytometric method for analyzing seven immune cell subsets from a 25 µl blood sample is described.

What is pleural malignant mesothelioma?
Pleural malignant mesothelioma is a type of cancer that affects the lining of the lungs and is often associated with asbestos exposure.
Why is an orthotopic model important?
Orthotopic models mimic the natural environment of tumors, providing more accurate insights into tumor behavior and treatment responses.
What is flow cytometry?
Flow cytometry is a technique used to analyze the physical and chemical characteristics of cells or particles in a fluid as they pass through a laser.
How does this study contribute to cancer research?
This study provides a new model for understanding the immune response in pleural malignant mesothelioma, which can aid in developing targeted therapies.
What are immune cell subsets?
Immune cell subsets refer to different types of immune cells that play various roles in the immune response, such as T cells, B cells, and macrophages.
Can this model be used for testing new treatments?
Yes, the established model can be utilized to evaluate the efficacy of new therapeutic strategies for pleural malignant mesothelioma.
