Fig. 6From: Fluid-induced, shear stress-regulated extracellular matrix and matrix metalloproteinase genes expression on human annulus fibrosus cellsSemi-quantitative PCR for relative quantitation of metalloproteinase genes expression after 1 and 10 dyne/cm2 fluid-induced shear stress for 4 h. Semi-quantitative PCR was used to determine relative quantitative gene expression of a MMP-1, b MMP-3 and c ADAMTS-4. Data represent meanāĀ±āstandard deviation (nā=ā6). Differences were significant between groups with different letters (Pā<ā0.05). Differences were not significant between groups with the same letterBack to article page
