Abstract
Degenerative scoliosis (DS), encompassing conditions like spondylolisthesis and spinal stenosis, is a common type of spinal deformity. Lumbar interbody fusion (LIF) stands as a conventional surgical intervention for this ailment, aiming at decompression, restoration of intervertebral height, and stabilization of motion segments. Despite its widespread use, the precise mechanism underlying spinal fusion remains elusive. In this review, our focus lies on endochondral ossification for spinal fusion, a process involving vertebral development and bone healing. Endochondral ossification is the key step for the successful vertebral fusion. Endochondral ossification can persist in hypoxic conditions and promote the parallel development of angiogenesis and osteogenesis, which corresponds to the fusion process of new bone formation in the hypoxic region between the vertebrae. The ideal material for interbody fusion cages should have the following characteristics: (1) Good biocompatibility; (2) Stable chemical properties; (3) Biomechanical properties similar to bone tissue; (4) Promotion of bone fusion; (5) Favorable for imaging observation; (6) Biodegradability. Utilizing cartilage-derived bone-like constructs holds promise in promoting bony fusion post-operation, thus warranting exploration in the context of spinal fusion procedures.

Abstract
The current design scheme on anti-cancer materials is mainly through tuning the mechanical properties of the materials to induce apoptosis in cancer cells, with the involvement of Rho/ROCK signaling pathway. We hypothesize that tuning the motility is another potential important approach to modifying the tumor microenvironment and inducing tumor apoptosis. To this aim, we have prepared RGD-modified substrates to regulate cell motility through modification of RGD with different concentrations, and systematically examined the effect of motility on the apoptosis of tumor cells, and the potential involvement of Wnt signaling pathway. Our studies indicated that RGD modification could be readily used to tune the motility of cancer cells. High RGD concentration significantly suppressed the migration of cancer cells, leading to significantly increased apoptosis rate, about three times of that of the unmodified samples. Western-blot analysis also showed that cell with low motility expressed more caspase-3 and PARP proteins. Further RNA sequence study strongly suggested that low motility inhibited the canonical Wnt signaling pathway, which in turn led to the activation of the mitochondria-associated caspase signaling pathway, and ultimately to the apoptosis of osteosarcoma cells. Activation of the Wnt-β-catenin pathway through HLY78 significantly suppressed the apoptosis of MG-63 cells, further suggesting the critical role of Wnt pathway in motility-regulated-apoptosis of tumor cells. Our findings shed insights to understand the underlying mechanisms that induced the tumor cell apoptosis, and might provide new strategy for designing the novel anti-tumor materials.

Abstract
It is of significance to construct the immunomodulatory and osteogenic microenvironment for three dimension (3D) regeneration of bone tissues. 3D scaffolds, with various chemical composition, macroporous structure and surface characteristics offer a beneficial microenvironment for bone tissue regeneration. However, there is a gap between the well-ordered surface microstructure of bioceramic scaffolds and immune microenvironment for bone regeneration. In this study, a gear-inspired 3D scaffold with well-ordered surface microstructure was successfully prepared through a modified extrusion-based 3D printing strategy for immunomodulation and bone regeneration. The prepared gear-inspired scaffolds could induce M2 phenotype polarization of macrophages and further promoted osteogenic differentiation of bone mesenchymal stem cells in vitro. The subsequent in vivo study demonstrated that the gear-inspired scaffolds were able to attenuate inflammation and further promote new bone formation. The study develops a facile strategy to construct well-ordered surface microstructure which plays a key role in 3D immunomodulatory and osteogenic microenvironment for bone tissue engineering and regenerative medicine.

Abstract
Osteoporosis is a widespread disease characterized by bone mass loss and microarchitectural deterioration. The significant side effects of clinical drugs make mesenchymal stem cells (MSCs)-based therapy gain increasing focus in the treatment of osteoporosis. MSCs need to migrate to the site of damage and undergo differentiation in order to participate in the subsequent bone repair process. Therefore, the homing ability of MSCs may be related to the repair ability. Here, we proposed a novel method to screen MSCs with high migration capacity and confirmed that these MSCs exhibited higher osteogenic differentiation ability both in vivo and in vitro. Further researches indicated that MSCs with high migration ability could partly rescue the bone loss of ovarectomized (OVX) rats. Higher expression of Platelet-derived growth factors receptor β- (PDGFRβ) and more nuclear transduction of β-catenin in MSCs with high migration ability may be responsible for biological functions. This article may provide a method to improve the efficacy of MSCs-based therapy in the clinic.

Abstract
BACKGROUND The process of osteointegration, as key point has the activation of mesenchymal cells at implant-bone interspace, their differentiation into osteoblasts and connection between the implant surface and the surrounding bone. MAIN TEXT Implant surfaces composed by biocompatible, organism-friendly materials require changes in content and surface morphology; changes that may further stimulate mesenchymal cell activation. The way the implant surfaces are affected with advantages and disadvantages, that typically bring each methodology, is also the purpose of this study. The study is of review type, based on finding articles about implant surface modification, with the aim of promoting the mesenchymal cell activation, utilizing keyword combination. CONCLUSIONS Implant success beyond the human element of the practicioner and the protocol element of implant treatment, also relies on the application of the right type of implant, at the right implant site, in accordance with oral and individual health status of the patient. Implant success does not depend on type of "coating" material of the implants. Based at this physiological process, the success or implant failure is not a process depending on the type of selected implant, because types of synthetic or natural materials that promote osteointegration are relatively in large number.

Abstract
Mechanical signals play a central role in cell fate determination and differentiation in both physiologic and pathologic circumstances. Such signals may be delivered using materials to generate discrete microenvironments for the purposes of tissue regeneration and have garnered increasing attention in recent years. Unlike the addition of progenitor cells or growth factors, delivery of a microenvironment is particularly attractive in that it may reduce the known untoward consequences of the former two strategies, such as excessive proliferation and potential malignant transformation. Additionally, the ability to spatially modulate the fabrication of materials allows for the creation of multiple microenvironments, particularly attractive for regenerating complex tissues. While many regenerative materials have been developed and tested for augmentation of specific cellular responses, the intersection between cell biology and material interactions have been difficult to dissect due to the complexity of both physical and chemical interactions. Specifically, modulating materials to target individual signaling pathways is an avenue of interdisciplinary research that may lead to a more effective method of optimizing regenerative materials. In this work, the aim is to summarize the major mechanotransduction pathways for osteogenic differentiation and to consolidate the known materials and material properties that activate such pathways.

Abstract
Chitosan-Bioactive glass (CS-BG) nanocomposite coatings were developed on the Ti-6Al-4 V alloy to investigate the effect of the BG content on the adhesion strength, bioactivity, bio-corrosion, wettability and roughness. For this purpose, BG nanoparticles were synthesized using a sol-gel process. Three nanocomposite coatings with different concentrations of BG (0.5, 1 and 1.5 g/L) were fabricated through cathodic electrophoretic deposition (EPD). The surface morphology and composition of the coatings revealed the formation of compact coatings with a uniform distribution of BG nanoparticles. Increasing the BG content enhanced the deposition rate of CS-BG nanocomposite coatings and raised the coating thickness. Moreover, the CS-BG coating containing 1.5 g/L BG showed the best corrosion performance owing to the more uniform distribution of BG nanoparticles and its higher thickness. Also, increasing the BG concentration improved the adhesion strength, raised the roughness, and promoted wettability. Further, in-vitro bioactivity evaluation of the coated and uncoated specimens in SBF revealed that the formation of bone-like apatite was significantly encouraged on the surface of CS-BG coatings, as compared to the Ti-6Al-4 V uncoated sample. So, the apatite-forming ability of the coatings was improved by increasing the BG content. For in vitro investigation, osteoblast-like cell line MG63 were cultured on Ti-6Al-4 V substrate coated with CS-BG and cellular behavior was evaluated. Results demonstrated good cell attachment with no significant levels of cytotoxicity during 5 days of culture. Therefore, the electrophoretic deposition of the CS-1.5 g/L BG coating could successfully enhance the adhesion strength, bioactivity, corrosion and cellular performance of the substrate.

Abstract
BACKGROUND Dental implants are an important option for replacement of missing teeth. A major clinical challenge is how best to accelerate bone regeneration and reduce the healing time for functional restoration after implant placement. A sclerostin-neutralizing antibody (Scl-Ab) has been shown to enhance alveolar bone formation and fracture repair. The aim of this study was to investigate the effects of systemic administration of Scl-Ab on dental implant osseointegration and bone regeneration in an experimental alveolar ridge tooth extraction model. MATERIALS AND METHODS To investigate the effects of Scl-Ab on bone regeneration and dental implant osseointegration, an experimental alveolar bone osteotomy rat model was adopted. One month after extraction of maxillary right first molars, osteotomy defects were created at the coronal aspect of each of the extraction sites, and 1 × 2-mm custom titanium implants were installed into the osteotomies. Coincident with implant placement, Scl-Ab was administered subcutaneously at a dose of 25 mg/kg twice weekly for 10-28 days and compared with a vehicle control. Animals were sacrificed 10, 14, and 28 days after surgery, and maxillae were harvested and analyzed by microcomputed tomography (microCT), histology, and histomorphometry. RESULTS microCT analysis demonstrated that the maxillary bone volume fraction was approximately 2- to 2.5-fold greater in Scl-Ab-treated animals compared with vehicle alone at days 14 and 28. Consistent with those findings, two-dimensional bone fill percentages within the coronal osteotomy sites were highest in Scl-Ab treatment groups at 28 days. In addition, bone-implant contact at 28 days was approximately twofold greater in the Scl-Ab group compared with the vehicle control. CONCLUSIONS These results indicate that systemic Scl-Ab administration enhances osseointegration and bone regeneration around dental implants. This approach offers potential as a treatment modality for patients with low bone mass or bone defects to achieve more predictable bone regeneration at alveolar bone defects and to enhance dental implant osseointegration.

Abstract
Basic cellular events, such as focal adhesion and cytoskeleton organization, have been reported to be actively involved in fate decision process of stem cells, besides chemical and physical cues. Stem cell migration is critical in regulating various stem cell functions, but its influence on MSC differentiation into specific lineages has been rarely exploited. In this study, we used RGD-modified substrates to regulate cell motility though different RGD concentrations and systematically analyzed the correlation between osteoblastic differentiation and cell migration, as well as the role of Wnt signaling pathway. High motility correlated well with the significantly enhanced potential of the MSCs to differentiate into the osteoblastic lineage, as suggested by the significant up-regulations of Runx2, ALP, OCN expressions. The results also suggested that enhanced MSC migration efficiently activated the canonical Wnt-β-catenin pathway and stimulated transcription activities leading to osteoblastic differentiation, likely through internal forces generated dynamically during migration. Blockage of the Wnt-β-catenin pathway through artificial down-regulation of LRP5/6 expression significantly suppressed the osteoblastic differentiation for samples with high MSC motilities, further corroborating the critical involvement of Wnt/β-catenin pathway in the cell migration induced mechanotransduction and MSC differentiation into osteoblastic lineage. Our findings provide important insight for understanding the complicate mechanisms involved in MSC fate selection process and bone regeneration, and would have significant implications in the optimal design of bone tissue engineering materials through regulating cell motility.

Abstract
The interplay between stem cells and their extracellular microenvironment is of critical importance to the stem cell-based therapeutics in regenerative medicine. Mineralized collagen is the main component of bone extracellular matrix, but the effect of interfacial properties of mineralized collagen on subsequent cellular behaviors is unclear. This study examined the role of surface chemistry of nanoscale mineralized collagen on human periodontal ligament stem cell (hPDLSC) fate decisions. The intrafibrillarly mineralized collagen (IMC), fabricated by a biomimetic bottom-up approach, showed a bonelike hierarchy with nanohydroxyapatites (HAs) periodically embedded within fibrils. The infrared spectrum of the IMC showed the presence of phosphate, carbonate, amide I and II bands; and infrared mapping displayed uniform and higher spatial distribution of mineralization in the IMC. However, the distribution of the phosphate group differed far from that of the amide I group in the extrafibrillarly mineralized collagen (EMC), in which flowerlike HA clusters randomly depositing around the surface of the fibrils. Moreover, a large quantity of extrafibrillar HAs covered up the C═O stretch and N-H in-plane bend, resulting in substantial reduction of amide I and II bands. Cell experiments demonstrated that the hPDLSCs seeded on the IMC exhibited a highly branched, osteoblast-like polygonal shape with extended pseudopodia and thick stress fiber formation; while cells on the EMC displayed a spindle shape with less branch points and thin actin fibril formation. Furthermore, the biocompatibility of EMC was much lower than that of IMC. Interestingly, even without osteogenic induction, mRNA levels of major osteogenic differentiation genes were highly expressed in the IMC during cultivation time. These data suggest that the IMC with a similar nanotopography and surface chemistry to natural mineralized collagen directs hPDLSCs toward osteoblast differentiation, providing a promising scaffold in bone tissue regeneration.
