Tumor Implantation and Injection of a Tumor Vaccine in a Mouse Model

Take an anesthetized and shaved mouse. Inject mouse skin cancer cells.

Due to the same genetic background, the host immune system does not reject the cancer cells, allowing them to grow into a tumor.

Measure the tumor dimensions periodically.

Take a tumor vaccine containing non-dividing skin cancer cells modified to secrete a cytokine that activates immune cells against the tumor.

Once the tumor grows to the desired size, inject the vaccine near the tumor.

The secreted cytokine binds to specific immune cells in the tumor region, triggering an immune signaling cascade.

This process recruits more immune cells to the tumor site.

Together, they target and destroy the cancer cells, suppressing the tumor growth.
