A femoral bone defect was created and filled with antibiotic embedded polymethyl methacrylate. Half of the animals in each group were sacrificed at week 6 and the pseudo-membranes formed were analyzed. In the remaining half, the cement was removed and the space was filled with autograft. After another 6\u2009weeks, the structures formed were examined radiologically, histologically, and biochemically.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>At week 6, both PRP and EGF groups had significantly higher membrane CD31, TGF-beta, and VEGF levels than controls. At week 12, when compared to controls, PRP and EGF groups had significantly higher membrane CD31 levels and the PRP group had significantly higher membrane TGF levels. Regarding bone tissue levels, PRP and EGF groups had significantly higher VEGF levels and the EGF group had significantly higher BMP levels.
