Mechanical properties of DAPF and adult rat spinal cord tissue. (a) Mean stress-strain curves of the linear region from three different regions of the cord, namely lumbar, thoracic and cervical regions (N = 3 BRs, n = 3 TRs/BR). The lumbar region has the highest resistance to applied stress. (b) Mean curves of the linear region of stress-strain curves for: thoracic spinal cord tissue, DAPF/B. mori silk single fibre, Polyglactin filament and Axoguard®. The stress/strain curves of DAPF and B. mori silk filaments (n = 7 TRs) were closest to those of rat spinal cord tissue. (c) The accelerated in vitro degradation test showed a statistical significant decrease in maximum force of DAPF after 40 and 60 days (n = 7 TRs).
