Fig. 5From: Fluid-induced, shear stress-regulated extracellular matrix and matrix metalloproteinase genes expression on human annulus fibrosus cellsSemi-quantitative PCR for relative quantitation of ECM genes expression after 1 and 10 dyne/cm2 fluid-induced shear stress for 4 h. The control group (0 dyne/cm2) was not subjected to fluid-induced shear stress on the bio-microfluidic device. Semi-quantitative PCR was used to determine relative quantitative gene expression of a COLI, b COLIII and c aggrecan. 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
