Extracellular vesicles (EVs) can deliver miRNAs between cells and play a crucial role in hepatoblastoma progression. In this study, we explored the differentially expressed miRNAs related to tumor cell-derived EVs and the mechanism by which EVs regulate hepatoblastoma progression. Methods. Bioinformatics analysis was performed to explore the differentially expressed miRNAs between the hepatoblastoma and adjacent normal tissues. TEM, NTA, and western blotting were conducted to identify EVs. The expression of miR-126-3p, miR-126-5p, miR-30b-3p, miR-30b-3p, SRY, IL-1\u03b1, IL-6, and TGF-\u03b2 was detected by RT-qPCR. Immunofluorescence (IF) was used to analyze the expression of PKH67, and flow cytometry was applied to assess the ratio of CD44+ CD90+ CD133+ cells. ELISA was used to evaluate the levels of IL-6 and TGF-\u03b2. A xenograft mouse model was constructed to detect the function of EVs with downregulated miR-126. IHC was performed to calculate \u03b2-catenin levels in tumor tissues. Results. miR-126 was upregulated in hepatoblastoma. EVs derived from hepatoblastoma cells significantly increased the ratio of CD44+ CD90+ CD133+ cells and increased the expression of IL-6, Oct4, SRY, and TGF-\u03b2 in bone marrow mesenchymal stem cells (BMSCs), while EVs with downregulated miR-126 reversed these phenomena. miR-126 downregulation notably attenuated hepatoblastoma tumor growth and decreased the ratio of CD44+ CD90+ CD133+ cells and increased the expression of IL-6, Oct4, SRY, TGF-\u03b2, and \u03b2-catenin in tumor tissues of mice. Furthermore, EVs with downregulated miR-126 inhibited the differentiation of BMSCs into cancer stem cells. Conclusions. Exosomal miR-126 derived from hepatoblastoma cells promoted the tumorigenesis of liver cancer through inducing the differentiation of BMSCs into cancer stem cells.<\/jats:p>","DOI":"10.1155\/2021\/6744715","type":"journal-article","created":{"date-parts":[[2021,10,30]],"date-time":"2021-10-30T01:50:07Z","timestamp":1635558607000},"page":"1-14","source":"Crossref","is-referenced-by-count":15,"title":["miR-126 in Extracellular Vesicles Derived from Hepatoblastoma Cells Promotes the Tumorigenesis of Hepatoblastoma through Inducing the Differentiation of BMSCs into Cancer Stem Cells"],"prefix":"10.1155","volume":"2021","author":[{"given":"Yu","family":"Hu","sequence":"first","affiliation":[{"name":"Department of General Surgery, Xiangya Hospital, Central South University, 410008 Changsha, Hunan Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongyan","family":"Zai","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Xiangya Hospital, Central South University, 410008 Changsha, Hunan Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Xiangya Hospital, Central South University, 410008 Changsha, Hunan Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuanbing","family":"Yao","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Xiangya Hospital, Central South University, 410008 Changsha, Hunan Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenglin","family":"Ou","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Xiangya Hospital, Central South University, 410008 Changsha, Hunan Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9864-5434","authenticated-orcid":true,"given":"Qin","family":"Zhu","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Xiangya Hospital, Central South University, 410008 Changsha, Hunan Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.20.25310"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.3390\/foods10030571"},{"issue":"3","key":"3","first-page":"849","article-title":"Genetic variations in base excision repair pathway genes and risk of hepatoblastoma: a seven-center case-control study","volume":"11","author":"Z.
