From: Matrix metalloproteinase 28, a novel matrix metalloproteinase, is constitutively expressed in human intervertebral disc tissue and is present in matrix of more degenerated discs

Figure 1

Gene expression for matrix metalloproteinase 28 and precursor in vivo in human annulus tissue. Relative gene expression levels for (a) matrix metalloproteinase (MMP) 28 and (b) MMP28 precursor in vivo in human annulus tissue according to grades of disc degeneration. Data presented as the mean ± standard error of the mean. Values inside bars show the number of specimens analyzed for the respective grade of disc tissue.
