CD4 and neoplasm: As induction of T cell proliferation is an important prerequisite to combat high tumor burden, we next labelled PBMC using CellTraceTM Violet and analyzed induction of CD4+ and CD8+ T cell counts (Figures 4A–C) and cell dye dilution (Figure S5) in cocultures with gastric, hepatic and pancreatic tumor cells upon treatment with 1 nM of CC-3 using flow cytometry.
