Figure 4From: Differential expression of type X collagen in a mechanically active 3-D chondrocyte culture system: a quantitative studyRelationship between strains in the central region versus overall strains. The strain values in the central region were approximately 1/2 (0.5 ± 0.07; n = 4) of the overall strain across a wide range of overall strain values generated by various power settings on the Bio-Stretch System. Each point in the graph represents a different power level tested.Back to article page
