简介：
Overview
This article describes the creation of an orthotopic mouse model of human pleural mesothelioma through the implantation of H2052/484 mesothelioma cells into the pleural cavity of athymic mice. This model allows for longitudinal monitoring of tumor development using non-invasive imaging techniques.
