Fig. 2From: Identification of peroxiredoxin II and its related molecules as potential biomarkers of dermal mesenchymal stem cell homing using network analysisProtein–protein interaction (PPI) networks of cell migration and intercellular adhesion biological processes. A, B PPI network constructed to screen hub genes. Node color: shades of green to blue represent high to low values of betweenness centrality (BC). Node size: circle size represents the node degrees. Larger and darker-colored nodes represent genes with more links. C, D Expression levels of hub genes detected using RT-qPCR. Data are presented as the mean ± SD from at least three independent experiments (*P < 0.05, **P < 0.01, ***P < 0.001)Back to article page
