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

Table 2

Design of the experiments. A complete factorial experiment was used to estimate the effects of temperature (T, 23 or 37^°C), hydration (in a phosphate-buffered saline solution: PBS or without: no PBS) and mechanical preconditioning (C, with: PC or without: no PC) on the mechanical and viscoelastic properties of collagen gels.

Condition	Factor
	T	H	C
1	23^°C	No PBS	No PC
2	23^°C	No PBS	PC
3	23^°C	PBS	No PC
4	23^°C	PBS	PC
5	37^°C	No PBS	No PC
6	37^°C	No PBS	PC
7	37^°C	PBS	No PC
8	37^°C	PBS	PC
