Figure 4. Protein-protein interaction network for proteins identified in our tandem mass spectrometry runs.

ECM components and select ECM receptors were submitted for analysis of protein interactions (using STRING-DB.org). Components at the cell membrane are in the upper left corner, basement membrane moving down and right toward the fibrillar collagens at the bottom. Immune cell related proteins discussed in the text are diagramed in the upper right on a macrophage.
