In this study, we evaluated the cell phenotype, proliferation, and differentiation potential, as well as the anti-oxidative stress ability of human umbilical cord-derived MSCs (hMSCs) manipulated with adipogenic priming and subsequent dedifferentiation. After an in vitro differentiation and dedifferentiation procedure, the resultant dedifferentiated hMSCs (De-hMSCs) displayed properties similar to their original counterparts, including immunophenotype and mesodermal potential. Upon re-induction, De-hMSCs exhibited a significantly higher adipogenic differentiation capability than unmanipulated hMSCs. Importantly, De-hMSCs showed a significantly enhanced ability to resist tert-butyl hydroperoxide (t-BHP) induced apoptosis compared to undifferentiated hMSCs. Mechanisms involving bcl-2 family proteins and autophagy may contribute to the demonstrated advantages of dedifferentiation-reprogrammed hMSCs. These results indicate that adipogenic dedifferentiation promotes adipogenesis and cell persistence, as well as preserves the stemness of human umbilical cord-derived MSCs that have been committed to the adipocytic lineage.

In this study, we examined the effect of Ang 1-7 on inflammation of white adipose tissue (WAT) in dietary-induced obese mice. Monocyte chemoattractant protein-1 (MCP-1) produced by white adipocytes and tumour necrosis factor-α (TNF-α) produced by macrophages are pro-inflammatory cytokines and interact to form a pathogenic loop to exacerbate obesity-induced inflammation. We found that Ang 1-7 reduced MCP-1 and TNF-α gene expressions and the number of crown-like structures, which are histological hallmarks of the pro-inflammatory process, in visceral epididymal WAT (eWAT) and reduced circulating MCP-1 and TNF-α levels, accompanied by improvement in insulin resistance, in dietary-induced obese mice. Furthermore, Ang 1-7 reduced MCP-1 and TNF-α secretions in 3T3-L1 white adipocytes and RAW 264.7 macrophages, respectively, which are <i>in vitro</i> experimental models mimicking obesity condition. Our results suggest that Ang 1-7 directly acts on WAT to mitigate obesity-induced inflammation. Thus, this study provides novel insights into the underlying mechanism of anti-obesity effects of Ang 1-7.</p>","PeriodicalId":7226,"journal":{"name":"Adipocyte","volume":"14 1","pages":"2449027"},"PeriodicalIF":3.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11730366/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142969170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
