However, since SSCs are few in mice, directly studying them is limited, requiring specialized <i>in vitro</i> cultivation. Feeder layers such as mouse embryonic fibroblasts (MEFs), SNL, neonate, and adult mouse testicular stromal feeder cells (TSCs) support <i>in vitro</i> survival and growth. To understand the effectiveness of these feeder layers on SSC proliferation, we compared MEF, SNL, neonatal, and adult TSCs. Furthermore, we identified hub genes and potential pathways in spermatogenesis. Two populations of differentiated and undifferentiated SSCs were compared for mouse SSC colony formation and proliferation effectiveness. Additionally, Cytoscape and STRING databases were employed for protein-protein interaction networks and functional gene enrichment. The expression of three hub genes, including <i>Dazl</i>, <i>Zbtb16</i>, and <i>Stra8</i>, was analyzed using dynamic array chips (Fluidigm) followed by statistical analysis. Our results indicated that undifferentiated SSCs favored MEF feeders, while differentiated SSCs thrived on SNL and primary TSC feeders for long-term culture. Functional enrichment results demonstrated hub genes involvement in cell differentiation, meiosis, regulation of meiotic nuclear division, cell development, and spermatogenesis. Furthermore, mRNA expression levels of <i>Stra8</i>, <i>Zbtb16</i>, and <i>Dazl</i> genes show different patterns among feeder layers and SSC differentiation phases.</p>","PeriodicalId":9708,"journal":{"name":"Cellular reprogramming","volume":" ","pages":"75-85"},"PeriodicalIF":1.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143662437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Guide RNAs (gRNAs) were designed to target the CYP19 gene and cloned into the pX459 vector.

Human umbilical cord MSCs (HucMSCs) were identified via osteogenesis and adipogenic differentiation, as well as flow cytometry.

Fluorescence microscopy revealed the uptake of PKH67-labeled EVs and Cy3-labeled microRNA-21-5p (miR-21-5p) by human skin fibroblasts (HSFs). EVs were cocultured with HSFs, and cell proliferation and migration were assessed using Cell Counting Kit-8, colony formation, scratch, and Transwell assays. miR-21-5p overexpression in EVs was evaluated for its role in promoting HSF functions. The expression levels of miR-21-5p, Krüppel-like factor 6 (KLF6), α-smooth muscle actin, and collagen type I alpha 1 chain were analyzed via quantitative real-time PCR and Western blotting. The interaction between miR-21-5p and KLF6 was confirmed through a dual-luciferase reporter gene assay. HucMSC-derived EVs enhanced the proliferation and migration of HSFs under high glucose by delivering miR-21-5p, which targeted and inhibited KLF6. Overexpression of KLF6 counteracted the pro-proliferative and migratory effects of EVs carrying miR-21-5p.
