Functional classification clustering analysis presenting gene ontology processes associated with the 642 differentially expressed genes in NGF-differentiated PC12 cells cultured on PMMA-PDMS versus PS (Enrichment Score>0.5, Final group member threshold – minimum 10 genes).

<p>a. Terms based on GOTERM_BP_FAT category, DAVID Bioinformatics Resources 6.7.</p><p>b. The overall enrichment score for the group based on the EASE scores of each term members.</p><p>c. P-value (or called EASE score) to determine the significance of gene-term enrichment with a modified Fisher’s exact test (EASE score).
