Bone is a vital organ with irreplaceable functions of movement, haematopoiesis, and protection of other organs. Its physiological homeostasis is mainly determined by the synergy of corresponding cells such as bone marrow derived stem cells, osteoblasts, and osteoclasts. Once the physiological equilibrium is broken, the bones will transform into a pathological state, resulting with diseases such as osteoporosis, osteoarthritis, rheumatoid arthritis, and osteosarcoma.

These nanoscale vesicles possess stable membrane structure and naturally encapsulate a variety of bioactive molecules, making them versatile tools in biomedical applications. However, clinical translation of BEVs faces challenges such as insufficient display of disease-specific antigens, excessive toxicity, and rapid clearance. Addressing these issues is crucial for the clinical translation of BEVs. In this review, we discuss recent advances in BEV engineering strategies aimed at addressing these limitations and expanding their therapeutic applications. We highlight approaches for loading exogenous cargo into BEVs, detoxification strategies, and the latest progress in the application of engineered BEVs for treating infectious diseases, cancer, and other disorders. Despite promising preclinical results, clinical translation is hindered by safety concerns, standardisation difficulties, and scalability issues. Future research should focus on optimising detoxification processes, establishing global standardisation, and improving production methods to facilitate successful clinical translation of engineered BEVs.

However, its clinical application is limited by the low skin permeability of many active drugs in its formulations. To overcome this challenge, advancements in skin permeation enhancement techniques are essential. Over the past decade, natural polymers have been increasingly incorporated into various nanocarriers due to their availability, biodegradability, and biocompatibility, offering new options for the effective dispersion of suspended solids. Furthermore, surface functionalisation of the numerous functional groups found in natural polymers allows them to be transformed into targeted and stimulus-responsive materials, enabling precise drug delivery to musculoskeletal tissues. This review examines the mechanisms of action of natural polymer-based transdermal drug delivery system, covering penetration enhancers, nanoparticles, microneedles, hydrogels, and nanofibres derived from chitosan, hyaluronic acid, sodium alginate, cellulose, and proteins, and their applications in treating musculoskeletal disorders.

In the present study, we synthesised three water-soluble C70 fullerene derivatives with thiophene-based solubilising addends and tested their cytotoxicity and the transcriptional activity of genes, which regulate an oxidative metabolism. Aliphatic chain length in the structure of the solubilising addend of the water-soluble fullerene derivative has been varied, and we revealed that a longer chain resulted in more pronounced antioxidant activity. Thus, the surface modification enhances the antioxidant properties of the compound and changes the nanoparticles impact on the genetic apparatus of the cell.

Given these positive results, we aimed to evaluate the biosafety and efficacy of AFGs in a non-human primate SCI model before exploring its potential in the clinic. In the present study, no significant adverse reactions were observed over 24 weeks following AFG implantation into 1-cm gaps in the hemisected thoracic spinal cords of monkeys (Macaca fascicularis). Scaffold implantation also reduced cystic cavity formation and encouraged axonal sprouting across the lesion site. Notably, detailed histological analysis demonstrated that AFG promoted high-density, sequential, and aligned nerve fibre regeneration, resulting in remyelination and vascularisation, ultimately leading to remarkable motor function recovery. These results indicate that AFG transplantation exhibits reliable biocompatibility and effectiveness in promoting spinal cord repair in a non-human primate SCI model. Owing to the similarities in genetics and physiology between non-human primates and humans, AFG transplantation therapy is likely suitable for use in human spinal cord repair.","PeriodicalId":58820,"journal":{"name":"Biomaterials Translational","volume":"6 3","pages":"334-344"},"PeriodicalIF":0.0,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12582039/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145446587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The osteoinductive properties of bone morphogenetic protein-2 (BMP2) have become a key therapeutic strategy in bone regeneration. However, the development of biodegradable composites that ensure biocompatibility, stability, efficient BMP2 loading, and controlled release remains unresolved. In this study, we designed PBVHx/soy lecithin (SL)/BMP2 controlled-release microspheres (sB2PM) based on the biodegradable material poly(3-hydroxybutyrate-co-3-hydroxyvalerate-co-3-hydroxyhexanoate) (PBVHx), incorporating SL to enable sustained BMP2 delivery and enhance capture. sB2PM microspheres exhibited uniform size (approximately 5 μm) and high BMP2 encapsulation efficiency (80.29%) compared to pure PBVHx-based microspheres (pPM). Due to PBVHx's biodegradability, BMP2 release was primarily degradation-driven, resulting in a controlled biphasic release profile. sB2PM achieved 62.79% cumulative BMP2 release over four weeks and continued to release BMP2 sustainably thereafter. Co-culturing sB2PM microspheres with human bone marrow-derived mesenchymal stem cells (hBMSCs) in a Transwell system showed enhanced cell proliferation, biocompatibility, and collagen secretion. Compared with pPM and B2PM, sB2PM significantly promoted osteogenic differentiation, increased alkaline phosphatase (ALP) activity, and upregulated osteogenic gene expression in hBMSCs, outperforming commercial hydroxyapatite microspheres. In a mouse hindlimb unloading osteoporosis model, micro computed tomography and histological evaluations confirmed that injectable sB2PM microspheres significantly enhanced bone regeneration, collagen secretion, and ALP and runt-related transcription factor 2 protein expression.

The slow release of magnesium ions allows for their effects on the target site for a long time, reducing the clearance of magnesium ions in the body, which significantly contributes to bone repair. Magnesium-based bioalloy scaffolds have received widespread attention for their favourable biocompatibility, degradability, and bone-forming properties and play an important role in bone regeneration and repair.
