They are also key elements leading to the pathological calcification of vasculature; however, we know surprisingly little about them. First characterized over 55 years ago, MVs are small membrane bound extracellular vesicles that provide an environment for the concentration of calcium and phosphate. This makes MVs the first step in producing calcium phosphate, leading to the nucleation of HA mineral within the extracellular matrix, the key process in biomineralization. In this review, we discuss the literature on MV biogenesis and explore their components in the context of extracellular vesicles (EVs) and exosomes. We consider MVs in light of the Minimal Information for Studies of Extracellular Vesicles (MISEV2023). In doing so, we identify striking parallels in the biogenesis, contents, and roles of MVs and exosomes, opening opportunities for new avenues of research and understanding. We also explore the debate around whether MVs really contain HA, and propose emerging technologies, particularly in the field of imaging, to improve our understanding of MVs and galvanise research in the area over the coming years. By taking a closer look at MV biogenesis, we will be able to make use of the emerging technologies around EVs more widely, with the aim of fully understanding these vital vesicles and harnessing their potential therapeutic benefits.</p>","PeriodicalId":185,"journal":{"name":"Journal of Bone and Mineral Research","volume":" ","pages":""},"PeriodicalIF":5.1,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144191310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forty percent of older US adults take multivitamin/multimineral (MVM) supplementation. The effects of MVM supplementation on fractures are unclear. Preclinical and observational studies suggest that MVM and flavanols may have beneficial effects on bone. We conducted an ancillary study to Cocoa Supplement and Multivitamin Outcomes Study (COSMOS; NCT05232669) designed to investigate incident fracture and injurious falls in 21 442 COSMOS participants (12 666 females aged ≥65 yr and 8776 males aged ≥60 yr) randomized in a 2 × 2 factorial design to 1 of 4 intervention groups: cocoa extract + MVM, cocoa extract + MVM placebo, cocoa extract placebo + MVM, or double placebo. The daily cocoa extract supplement contained 500 mg/d flavanols and 80 mg/d (-)-epicatechin (Mars Edge); the daily MVM supplement was Centrum Silver (Haleon). The median (interquartile range) duration of the intervention was 3.6 (3.2-4.2) yr. Annually, participants self-reported incident fractures. In intention-to-treat analyses, we examined the effects of cocoa extract and MVM on the primary outcomes of total clinical fracture (hip, upper leg, forearm/wrist, pelvis, upper arm/shoulder, spine, knee, or other), hip fracture, and nonvertebral fracture, and secondary outcomes of clinical spine, forearm/wrist, major osteoporotic, and pelvic fracture using Cox proportional hazards models. During the intervention period, 2083 incident clinical fractures occurred. Compared with placebo, cocoa extract was not significantly associated with lower risk of incident clinical fracture (adjusted hazard ratio [aHR] 1.03, 95% CI 0.95-1.12) or nonvertebral fracture (aHR 1.05, 95% CI 0.96-1.14). MVM supplementation was not associated with lower risk of total clinical fracture (aHR 1.09, 95% CI 1.00-1.19), hip fracture (aHR 1.06, 95% CI 0.80-1.42), or nonvertebral fracture (aHR 1.10, 95% CI 1.00-1.20).

Nevertheless, its involvement in regulating postnatal bone homeostasis and bone mass accrual remains unclear. In this study, we generated mice lacking Kdm6b gene specifically in mesenchyme and osteoprogenitor cells using a conditional strategy. The adult mice of both mutant strains had decreased cancellous bone mass. The absence of Kdm6b in mesenchyme led to decreased numbers of osteoblasts and osteoclasts, increased marrow adipocytes, as well as repressed bone formation and resorption. Additionally, Kdm6b-deficient bone marrow stromal cells (BMSCs) displayed impaired osteogenic differentiation and exerted an inhibitory effect on osteoclastogenesis. RNA-seq combined with gene expression analysis uncovered downregulation of collagen triple helix repeat containing 1 (CTHRC1) and a lower RANKL/osteoprotegerin (OPG) ratio in BMSCs of the mutant mice. Further mechanistic explorations demonstrated that KDM6B epigenetically upregulated CTHRC1 expression by removing the repressive H3K27me3 mark from its promoter, thereby triggering PKCδ/MAPKs signaling to facilitate osteoblast differentiation. CTHRC1 was able to mitigate the dysregulated osteogenic and adipogenic differentiation induced by Kdm6b deficiency. This study provides evidence that KDM6B regulates postnatal bone homeostasis through balancing osteoblast and osteoclast differentiation. Given its predominant promotion of osteoblastic bone formation over osteoclastic bone resorption, KDM6B tends to promote postnatal bone mass accrual.</p>","PeriodicalId":185,"journal":{"name":"Journal of Bone and Mineral Research","volume":" ","pages":"671-687"},"PeriodicalIF":5.1,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
