  1. Results from individual specimens are presented, as well as means and standard deviations. The scaffold and peripheral ROIs were not applicable for the control group.
  2. *No scaffold was present in the control specimens. This scaffold volume represents an inherent error in using intensity thresholds to compute the volume.
