As the infusion dose of antigen-specific T-cells can have an impact on the magnitude of tumor regression, as well as the number of viable tumor cells and T-cells that could still be detected on Day 21 during intravital imaging, initial experiments were performed to adoptively transfer titrated doses of OT-I+ CD8+ GFP+ T-cells into mice bearing established B78ChOva-mCherry tumors on Day 10. Here, CD8A is linked to neoplasm.
