Fig. 2From: The optimal scaffold for silk sericin-based bone graft: collagen versus gelatinThe results from micro-CT analysis. A The collagen group (group C) showed multiple calcified nodules in the bony defect. B The gelatin group (group G) also showed bone regeneration. However, it was less active compared with the collagen group. C Bone volume (BV) was measured in the region of interest. BV was significantly higher in group C than in group G (*P = 0.001)Back to article page
