Figure Lengend Snippet: A. Tri-culture of HT29 CRC cells (blue), senescent IMR90 fibroblasts (green), and NK-92 cells (unlabeled). B. Tri-culture of HT29 CRC cells (blue), proliferating IMR90 fibroblasts (green), and NK-92 cells (unlabeled) at 8-hour post- treatment timepoint. C. Quantification of senescent IMR90 + HT29 CRC cells + NK-92 tri-culture (panel A). D. Quantification of proliferating IMR90 + HT29 + NK-92 tri-culture (panel B). E. Quantification of senescent IMR90 + HT29 + TALL-104 tri-culture (panel G). F. Quantification of proliferating IMR90 + HT29 + TALL-104 tri-culture (panel H). G. Tri-culture of HT29 tumor cells (blue), senescent IMR90 fibroblasts (green), and TALL-104 T cells (unlabeled). H. Tri-culture of HT29 tumor cells (blue), proliferating IMR90 fibroblasts (green), and TALL-104 T cells (unlabeled). Ethidium homodimer (EthD-1) was used to visualize dead cells, 10x magnification, scale bar indicates 100 μm. One-way Anova followed by post-hoc Tukey’s multiple comparisons test was used to determine statistical significance at p < 0.05. The following symbols * and ** represent, p < 0.05 and p < 0.01, respectively. I. TALL-104 cell Granzyme B secretion post-ABT263 or ONC201 treatment was quantified using an IsoPlexis innate-immune chip single-cell cytokine profiling assay. J. A Uniform Manifold Approximation and Projection (UMAP) plot was used to cluster the single TALL-104 cells post-treatment as indicated using IsoPlexis technology. The cells were treated with ABT263 (2 µM) and ONC201 (2 µM), or the agents alone.
Article Snippet: Cell lines used in this study include human colorectal adenocarcinoma HT-29 cells (ATCC), normal lung fibroblast IMR90 cells (ATCC), human CD8+ cytotoxic TALL-104 cells (ATCC), and human natural killer NK-92 cells (previously provided by Dr. Kerry Campbell at Fox Chase Cancer Center).
