Supplementary Figure 2.TIL expanded under T-REP and C-REP conditions demonstrated equivalent MART-1-specific antitumor function on per-cell basis.TIL2935 were rapidly expanded using T-REP or C-REP for 14 days, and expanded CD8+ T cells were isolated by negative selection. Normalized numbers of MART-1 tetramer-reactive T cells were co-incubated with (A) Melanoma tumor cell lines Mel888 or HLA-A2-transduced Mel888A2 for 18h to assess IFN-g secretion, or (B) 51Cr labeled Mel888 (dotted lines) or Mel624 (solid lines) at indicated ratios for 4 hours to assess cytotoxicity by chromium release, or (C) T2 cells loaded with titrated amounts of MART-1 peptide for 18hrs to assess IFN-g release. (D) Post-expansion TIL were incubated with MART-1 peptide-pulsed T2 cells for 4 hours, and surface CD107a and intracellular IFN-g expression of gated MART-1 tetramer-reactive T cells was evaluated by flow cytometry.
