Differences of microtissue infiltrating major PBMC subpopulations in cancer cell monocultures and cancer cell/fibroblast co-cultures. To investigate the influence of tumor associated fibroblasts on immune cell infiltration, microtissue infiltrating major PBMC subpopulations were compared in microtissues consisting of A549 or Calu-6 with or without fibroblasts. Microtissues were co-incubated with PBMCs for 24 h. PMC = peripheral blood mononuclear cells. (n = 4) (*p < 0.05, **p < 0.005, ***p < 0.0005, ****p < 0.0001).
