Effects of a Pseudophysiological Environment on the Elastic and Viscoelastic Properties of Collagen Gels

Figure 7

Viscosities of ring-shaped collagen gels as a function of temperature (experiments performed either at 23°C or 37°C), hydration (either with or without a PBS solution), and mechanical preconditioning (either with or without mechanical preconditioning PC). Viscosities and are extracted from the first and the second term of the second-decay exponential regression of stress-strain relaxation curves obtained on collagen gels. Values are expressed as mean standard error. Significance: * ; ** ; *** .
