Figure 2From: High mechanical strain of primary intervertebral disc cells promotes secretion of inflammatory factors associated with disc degeneration and painCell-stretching device and strain protocols. (A) Schematic representation of mechanical stretching device used to apply low-frequency, high-magnitude strains. Graphical representation of the 8Â hours/16Â hours/8Â hours stretch protocol (B) and the 8Â hours/16Â hours/8Â hours/16Â hours (C) stretch protocol applied to cells.Back to article page
