Figure 5From: Characterization of heterotypic interaction effects in vitro to deconvolute global gene expression profiles in cancerModel of interaction effects. Upon close cell-cell contact the tumor cells (red) interact with the fibroblasts (yellow) (1), which express type I interferon (IFNα and IFNβ) (2). They in turn induce the interferon response genes predominantly in the tumor cells (3).Back to article page
