Figure 2 Differential gene screening and weighted gene coexpression network analysis. (A) A total of 1965 differential genes were screened at different time points (Sham, 1d, 3d, 5d, and 7d) after spinal cord injury (SCI). (B, C) Analysis of network topology showed that it met the scale-free topology threshold of 0.8 when β=16. (D) The heatmap of topological matrix showed the correlation network, in which each color represented a gene module.
