Skeletal muscle has been recently recognized as a secretory organ, with human myogenic progenitor cells (hMPCs) releasing extracellular vesicles (EVs). Here, we investigate the role of hMPC-derived EVs as mediators in skeletal muscle aging. This heterologous approach enables the analysis of age-related variations in EV burden and their impact on human muscle stem cell function. Therefore, we isolated EVs from hMPCs obtained from <i>vastus lateralis</i> muscle biopsies of young and elderly subjects. Then, we characterized EVs for specific marker, size, and concentration and analyzed their miRNA expression and proteomic profiles to delineate the bioactive cargo that influences recipient cell signaling. Next, we tested the ability of EVs to modulate on hMPCs. Specifically, we treated elderly hMPCs with young EVs and vice versa to analyze viability and differentiation. Our results demonstrate that EVs released by young hMPCs carry regenerative signals that mitigate the functional decline of aged muscle stem cells. Conversely, the EVs derived from elderly hMPCs compromise the regenerative capacity of their younger counterparts. Therefore, these results suggest that hMPCs release EVs and that their cargo is modulated by donor age. Moreover, the EVs significantly modulated hMPCs' viability and differentiation in cell culture.</p>","PeriodicalId":8826,"journal":{"name":"Biochemistry Research International","volume":"2026 ","pages":"5967706"},"PeriodicalIF":2.9,"publicationDate":"2026-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13310389/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148343728","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}

This research examined the anxiolytic, antidepressant, analgesic, and anti-inflammatory potentials of the acetone extract of <i>P. scandens</i> whole plant (APS) on in vivo mice and rat models. The elevated plus maze (EPM) and hole board tests (HBTs) were carried out to assess the anxiolytic effects, while antidepressant activity with forced swimming test (FST) and tail suspension test (TST) and the acetic acid-induced writhing and formalin-induced licking tests on Swiss albino mice were used to evaluate the analgesic activity, and the carrageenan-induced rat paw edema model was applied for anti-inflammatory effect. APS at 400 mg/kg exhibited significant anxiolytic (<i>p</i> < 0.001) and antidepressant (<i>p</i> < 0.01) effects. This study also demonstrated that APS has dose-dependent and significant analgesic effects for acetic acid-induced writhing (<i>p</i> < 0.05) and formalin-induced licking tests (<i>p</i> < 0.01), respectively, as well as anti-inflammatory (<i>p</i> < 0.001) activities compared to the standard diclofenac sodium. Furthermore, 11 compounds were detected in the extract through GC-MS. These phytochemicals exhibited significant binding affinities, excellent pharmacokinetics, and a safe toxicological profile, as reported by in silico molecular docking and ADMET analysis. The outcomes of this study confirmed that the presence of bioactive compounds in APS offers it considerable potential as a multimodal therapeutic substance with neuropharmacological, analgesic, and anti-inflammatory properties.</p>","PeriodicalId":8826,"journal":{"name":"Biochemistry Research International","volume":"2026 ","pages":"2685178"},"PeriodicalIF":2.9,"publicationDate":"2026-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13100811/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147760983","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}
