Abstract
We performed a morphological study of the bone tissue after implantation of a cryogenically structured albumin sponge containing a bioregulator isolated from blood serum into an extensive experimental defect of the femur. By day 90, no complete reparation of the bone tissue was achieved in the control group (without implantation of 3D carrier), a loose spongy bone is formed at the site of the defect. After implantation of the 3D carrier without serum bioregulator, the defect was closed, but the formed bone was loose and contained no inflammation foci. After the defect was filed with the albumin sponge with the bioregulator, the repair pattern corresponded to the processes of epimorphic tissue regeneration. The results suggest that cryogenically structured protein material in combination with a serum bioregulator ensured complete restoration of the bone tissue.
