Molecular pathway analysis of regulated membrane protein changes in RLSCs as they undergo hepatocytic differentiation. The shown network (Network 1) reveals protein interactions involved in cell-to-cell signaling and interaction, tissue development and cellular movement processes. Red represents an increase in protein expression, whereas green represents a decrease in expression level; the color intensity represents the degree of abundance change. A solid line indicates a direct interaction, and a dashed line indicates an indirect interaction.
