Bone Mesenchymal Stem Cells Contribute to Ligament Regeneration and Graft–Bone Healing after Anterior Cruciate Ligament Reconstruction with Silk–Collagen Scaffold

Immunohistochemistry staining of grafts in the knee cavity specific for tenascin-C in the S group and S/C group to assess ligament regeneration: the density mean of immunoreactivity was higher in the S/C group than in the S group at 4 weeks (a) and 16 weeks (b) after the operation.
