Schematic comparison of a pathway biology model (A) to a network biology model (B). Arrows depict interactions between signaling molecules. In a pathway biology model (A), genomic information regulating a cell fate is mediated by a linear pathway, where every downstream function is directly affected by an upstream signaling molecule. In a network biology model, genomic information controlling a certain cell fate is mediated by a network of interacting molecules.
