Extract of gene expression.

Fold changes in gene expression in the gel type and sponge type scaffolds including the “active zone” with and without platelet-derived growth factor-BB (PDGF) was assessed. The data is presented relative to the gel type scaffolds without PDGF. The area under the curve (AUC) above 1 and below −1 was calculated to indicate up-regulation and down-regulation, respectively. Genes are sorted based on the level of regulation in the scaffold. Up-regulation in the scaffold: bold and underlined>10; bold>5; italic>2; Down-regulation in the scaffold: bold and underlinedbolditalicExtract of gene expression.
