STRING analysis of protein networks. STRING identified 125 protein nodes within the 143 hNSC-upregulated genes. The nodes formed 9 distinct networks with 131 edges under the application of a high stringency filter. Protein nodes were mcl-clustered with an inflation parameter of three, and edges indicate various types of node interaction that are depicted by individual colors. Smaller protein nodes indicate a lack of 3D structural information about the individual protein
