Tissue composition of fracture calli 14 and 21 days after injury.
Abstract<p>Callus composition of mice 14 and 21 days post-injury. (A) Mice with TXT displayed significantly more cartilage in comparison to O<sub>2</sub> treated mice after 14 days. (B) Analysis after 21 days did not reveal intergroup differences. (C-E) Representative Safranin-O stained callus sections 14 days after injury. Markedly more cartilage (stained red) was observed in F+TXT mice compared to the other groups. TOT = total osseous tissue, Cg = cartilage, FT = fibrous tissue. Scale bars: 500 μm. Data represent medians and quartiles. Specimen numbers for each group are depicted. *p<0.05.</p
