Quantification of the callus composition after 14 and 28 days of fracture healing using digital image analysis. A/D: Whole callus area was determined [mm²]. Area of soft tissue (B/E) as well as Cartilage area (C/F) were measured as depicted in Figure 3A and displayed as a ratio to the whole callus area [%]. Wild type: n = 10; hTNFtg: n = 5; hTNFtg + TNFi: n = 7, * p < 0.05, dashed line p < 0.1, tendency.
