Distribution of genes in each cluster according to their functions.

<p>Relative distribution of genes in each cluster subdivided according to their functions. Cell division, genes involved in cell division, proliferation, apoptosis; Growth factors, genes for growth factors and their receptors; GF reg, growth factor regulatory molecules and transcription factors; Inflammation, cytokines, chemokines and their receptors; Inflam reg, inflammatory mediators, signaling molecules, transcription factors, and regulators; ECM, extracellular matrix proteins; ECM reg, Proteases, regulators of ECM synthesis and breakdown; Others genes involved in cell metabolism, transporters and ion channels and genes of unknown function (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0024320#pone.0024320.s002" target="_blank">Tables S1</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0024320#pone.0024320.s003" target="_blank">S2</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0024320#pone.0024320.s004" target="_blank">S3</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0024320#pone.0024320.s005" target="_blank">S4</a>, and S5).</p>
