WebApr 14, 2024 · Abstract. Tumor infiltrating lymphocytes (TIL) have shown promising efficacy in immunologically “hot” solid tumors that have a high level of T cell infiltration, such as melanoma. However, current treatment regimens require high dose IL-2 administration to support TIL survival, which limits their clinical applications due to IL-2 related toxicity. … WebJun 23, 2024 · Here we describe an approach to simultaneously monitor the invasive behavior in 3D of cancer cell spheroids and T-cell cytotoxicity in co-culture. Spheroid formation is driven by enhanced cell-cell interactions in scaffold-free agarose microwell casts with U-shaped bottoms.
