Therapy-induced senescence (TIS) may contribute to therapy resistance; however, evidence also suggests that senescent cells (SnCs) may promote anti-tumor immunity. Here, we present a protocol for examining the capability of TIS to stimulate type 1 conventional CD103+ dendritic cells (DCs). We describe steps for isolating and differentiating CD103+ DCs from murine bone marrow, inducing senescence in murine colon carcinoma cell line CT26, and coculturing DCs with SnCs. We then detail the flow cytometric analysis of DC maturation and activation. For complete details on the use and execution of this protocol, please refer to Liu et al. (2022)1 and Liu et al. (2023).2.
