Mechanical characterization of collagen gels (~5 and ~12 mm in inner and outer diameter) after compaction in the presence versus absence of L682777. a After 72 h of compaction, gels were uniaxially stretched at a strain rate of 5 % per minute for 7 min, followed by a relaxation phase of 15 min. b The visco-elastic gels were characterized by slope, relative decrease in maximal force and the time until half the force decay was reached. c L682777 had no statistically significant effect on the visco-elastic properties of the collagen gels. n = 6 for both groups
