Figure 5. DEGs and biological processes associated with effects of ahNSCs. (A) DEGs among the primary cortical neurons in the control, OGD, and NSC-CM group was filtered out, and then hierarchical clustering was performed. (B) With 53 genes whose expression were up-regulated in the OGD + NSC-CM group compared to the OGD group (> 2, up-regulated genes) biological process clustering was performed. (C) Expression of the top eight up-regulated genes of the NSC-CM group was illustrated at heatmap. (D) High expression of the top eight up-regulated genes was examined by qRT-PCR (n = 3 per group). * P < 0.05 ** P < 0.01.
