By using dynamic imaging microscopy, we found that endogenous CD8 T cells form long-lived interaction with TAMs in the tumor stroma. Doctors may monitor small tumors to see if they grow over time and to determine if they require surgery or not. This is a possibility any time the immune cells are sourced directly from human blood (PBMCs).
