bone healing
Spinal fusion and bone defects after injuries, removal of bone tumors, and infections require repair by implantation. In this study, we show self‐assembling peptide (SPG‐178) hydrogel‐induced bone healing in vivo. Posterolateral lumbar fusion and tibial intramedullary models of rabbits were prepared. In the tibia model, micro‐CT analysis revealed a significantly higher degree of newly formed bone matrix in the SPG‐178 group compared to the other groups. SEM/3D micrographs showed that the cavity filled with SPG‐178 had collagen fibers attached to host bone. After 28 days, samples from the SPG‐178 group showed significant repair of the defect. In the posterolateral lumbar fusion models, micro‐CT showed a tendency for a higher degree of newly formed bone matrix in the SPG‐178 group compared to the β‐TCP and bone chips only groups. Von Kossa staining showed marked new bone formation attached to the lamina that was most prominent at the implanted SPG‐178 composite margin. SPG‐178 is a material that is likely to be used in clinical applications because it has several benefits. These include its favorable bone conduction properties, its ability to act as a support for various cells and growth factors, its lack of infection risk compared with materials of animal origin such as ECM, and the ease with which it can be used to fill defects with complex shapes and be combined with a wide range of other materials.
