Summary: This study investigates the effects of copper-containing octacalcium phosphate (OCP) on angiogenesis in bone regeneration. The results show that low-Cu-OCP enhances the density of HUVEC capillary cross-linking and promotes angiogenesis and bone regeneration in vivo.

Summary: The effect of the dura mater on the integration of porous titanium implants and cranial bone was evaluated in this study. It was found that the group with intact dura mater showed significantly higher bone volume/total volume and trabecular number. Histological analysis also revealed more newly formed bone and calcification deposition in this group. These findings indicate that having an intact dura mater improves the osteogenesis and osteointegration properties of porous titanium implants.

Summary: This study focuses on the fabrication and regeneration potential of a composite implant composed of MgAl layered double hydroxides (LDH), gelatin, and diosgenin, in experimentally-induced tibial defects in rabbits. The implant is characterized and tested for its sustained release of diosgenin and osteogenic activity. The results show that the implant stimulates the expression of genes associated with osteoblastic activities and promotes faster bone formation. Histological and radiographical analysis also confirm the enhanced healing capacity of the implant. This research demonstrates the importance of using a composite implant to aid in bone regeneration and identifies key biomarkers involved in osteogenesis.

Summary: The study found that implanting a 900mm pore size 3D-printed PCL scaffold can facilitate new bone formation in critical-size calvarial defects, while adding PRF did not provide additional advantages.

Summary: Bone defects in the craniofacial skeleton can cause aesthetic and functional problems and loss of protection to vital structures. This study examined the use of different bone replacement materials in a critical size defect model in sheep. The results showed that titanium and PDLLA/CC scaffolds had excellent osseointegration properties, making them suitable for bone defect repair in the craniofacial skeleton.

Summary: In this study, three types of OCPs were compared to commercially available 8-TCP for their potential to promote bone formation in rat tibias with defects. The results showed that OCP/Alg was equivalent to 8-TCP in promoting bone bridge formation and had better biodegradability. OCP/Col accelerated bone formation in defect repair.

Summary: The simvastatin derivative KMUHC-01 has been found to have a positive effect on promoting bone defect healing, with lower cytotoxicity compared to simvastatin. The new bone microstructure showed improved bone volume and biomechanical tests revealed increased maximal strength in the KMUHC-01 group. Further studies are needed to determine the bioavailability and bone-forming efficacy of KMUHC-01 through systemic administration.

Summary: The study found that dentin lysate coating did not significantly affect bone regeneration in rat calvarial defects, with nearly complete defect closure even in untreated defects. Therefore, conclusions cannot be drawn regarding the stimulation of bone regeneration by dentin lysates.

Summary: The study evaluated the ability of 3DPBC-DIPY scaffolds to regenerate bone in critically sized calvarial defects in a skeletally immature pig model. Results showed that scaffold-induced bone growth was significantly greater than in negative controls and scaffolds with caps produced more bone generation than those without. The regenerated bone had similar properties to native bone.

Summary: A cell-free scaffold engineering strategy that integrates strontium and highly bioactive serum exosomes has been developed for the treatment of large bone defects. The scaffold can maintain bone morphological characteristics and accelerate bone formation through controlled release of strontium, while the serum exosomes extracted from the fracture rabbit model promote osteogenesis and angiogenesis. The SrTi scaffold + BF EXO composite significantly accelerates bone repair in the radial critical bone defect of rabbits.
