Establishing a Mouse Model of Pleural Disseminated Lung Cancer

Abstract

Source: Yasui, H., et al. Near Infrared Photoimmunotherapy for Mouse Models of Pleural Dissemination. J. Vis. Exp. (2021)

This video demonstrates a method to generate a mouse model of pleural dissemination by injecting lung cancer cell suspension into the thoracic cavity of an immunodeficient mouse.

Protocol

All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board.

1. Generation of a pleural dissemination model

1. Prepare luciferase-expressing target cells and suspend 1.0 × 10⁶ target cells in 100 µL of phosphate-buffered saline (PBS)
   NOTE: Intrathoracic cancer cells such as lung cancer and MPM are suitable as target cells. Luciferase-expressing cells were prepared via luciferase gene transfection, and high expression of luciferase was confirmed after > 10 cell passages. Cells....

Results

Figure 1: Easy hand-made device for cell transplantation. Attach the stopper made with polystyrene foam to the 30G needle so that the tip remains at 5 mm. The tip of the needle should be bent to avoid pneumothorax.
