Stress relaxation	Random	Aligned	Random	Aligned
After 1 min (%)	3.94±0.41	7.32±0.29	5.58±0.73	7.30±0.47
After 5 min (%)	9.53±3.47	12.97±1.49	13.78±0.19^a	19.05±3.64^a

18% axial strain
	Acellular		Cellular
Stress relaxation	Random	Aligned	Random	Aligned
After 1 min (%)	6.32±1.48	8.27±0.22	5.37±2.50	7.78±0.71
After 5 min (%)	10.93±1.35	13.30±1.21	9.87±0.18	14.34±2.43
