The comparison of these values with national and internationally accepted regulations was conducted, and evaluation of health risks for consumers was performed. Oncorhynchus mykiss samples were bought in April, May, and June of 2022 and 2023. The heavy metal concentrations were determined using inductively coupled plasma mass spectrometry (ICP-MS). Fish tissues were wet digested in Teflon vessels. The outcomes were contrasted with established regulatory limits for heavy metals in fish. Fortunately, the metal concentrations detected in the fillets were found to be below the permissible levels set by regulations, indicating that the fish were not significantly contaminated. Furthermore, the estimated daily intake (EDI) and target hazard quotient (THQ) values, which are utilized to evaluate the possible health risks connected with heavy metal exposure, were calculated. It was reassuring to find that both EDI and THQ values were below the acceptable thresholds, suggesting that the consumption of O. mykiss is not likely to pose a threat to human health.

The biological behavior of mesenchymal stem cells is notably influenced by varying concentrations of magnesium (Mg<sup>2+</sup>), strontium (Sr<sup>2+</sup>), and zinc (Zn<sup>2+</sup>) ions; however, their specific effects on hMSMSCs have not been comprehensively studied. We isolated hMSMSCs and identified their mesenchymal stem cell characteristics by flow cytometry and multilineage differentiation experiments. Subsequently, the hMSMSCs were cultured in media containing different concentrations of these metal ions. The proliferation and viability of hMSMSCs were assessed using CCK-8 and Calcein AM/PI staining. After osteogenic induction, cells were evaluated for alkaline phosphatase (ALP) activity, ALP staining, and Alizarin Red staining. Additionally, qRT-PCR was used to detect differences in osteogenic gene expression, and immunofluorescence staining was used to observe variations in OCN protein levels. The results indicated that 1 mM Mg<sup>2+</sup>, 0.01 mM Sr<sup>2+</sup>, and 0.001 mM Zn<sup>2+</sup> significantly improved the proliferation and activity of hMSMSCs. These concentrations also notably enhanced ALP secretion, increased bone-related gene expression, and augmented osteocalcin expression and formation of extracellular calcium nodules, thereby improving osteogenic differentiation. However, higher concentrations of Mg<sup>2+</sup>, Sr<sup>2+</sup>, and Zn<sup>2+</sup> decreased cell viability and osteogenic differentiation. Mg<sup>2+</sup>, Sr<sup>2+</sup>, and Zn<sup>2+</sup> promote osteogenic differentiation and proliferation of hMSMSCs in a concentration-dependent manner, indicating that the type and concentration of ions in the extracellular environment can significantly alter hMSMSCs behavior, which is a crucial consideration for material design in maxillary sinus elevation applications.</p>","PeriodicalId":8917,"journal":{"name":"Biological Trace Element Research","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141987359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
