Schematic of matrix metalloproteinase gene expression. Matrix metalloproteinase gene expression is represented in each box. A) Microarray results are represented by fold change (FC) from day 0. B) Normalized counts are represented from the 454 cDNA sequencing experiment. Figures 2 to 4 were created using GenMAPP . Figure 2 was modified from a MAPP originally created by Gladstone Institutes.
