Tumor-infiltrating lymphocytes (TIL) were isolated from a human melanoma metastatic to the abdomen. The TIL were 99% CD3+ and 99% CD4+ and CD8-. They were dependent on interleukin-2 (IL-2) for growth, as measured in a thymidine uptake assay, and were not cytotoxic to autologous or allogeneic melanoma or K562. When co-cultured with irradiated autologous tumor cells, or tumor cell supernatants, the TIL not only did...
