摘要: 【目的】建立绵羊(Ovis aries)诱导性多能干细胞系,为绵羊转基因育种、应用绵羊诱导性多能干细胞奠定基础。【方法】利用电转将OCT4、SOX2、KLF4、l-Myc、Lin28转染至绵羊成纤维细胞中并诱导培养至有光滑隆起、边缘整齐的细胞克隆,形态学、碱性磷酸酶(AP)染色、免疫荧光染色以及实时荧光定量PCR检测克隆细胞的生物学特性;利用高通量测序技术对诱导0、10、20、30 d的阳性细胞的差异表达基因进行筛选。【结果】克隆细胞中SOX2、OCT4、SSEA-1蛋白免疫荧光染色均呈阳性; OCT4、SOX2、Nanog基因表达量均极显著高于成纤维细胞;0和30 d转录组测序表明,被注释到GO数据库的差异表达基因有9 465个,其中,上调基因6 987个,下调基因2 478个;KEGG分析共有5 773个基因注释到259个通路中,其中,P53信号通路显著富集,且其在干细胞增殖方面起着非常重要的作用。【结论】初步成功建立了绵羊诱导性多能干细胞。

Abstract: 【Objective】 The aim of this study is to establish sheep (ovis aries) induced multifunctional cell lines in the hope of laying the foundation for sheep transgenic breeding.【Method】Colonies derived from ovine fibroblasts transfected with OCT4, SOX2, KLF4, 1-Myc and Lin 28 by electroporation displayed smooth domes with sharp edges when grown in human iPSCs medium. Morphology, alkaline phosphatase(AP) staining, immunofluorescence staining and real-time fluorescence quantitative PCR were used to detect the biological characteristics of cloned cells. Also, the experiment adopted the high fluxtranscriptome sequencing technology to screen the differentially expressed genes of 0 d, 10 d, 20 d and 30 d cloned cells.【Result】The results showed that the SOX2, OCT4, SSEA-1 protein and immunofluorescence staining of the cloned cells were positive. The expression of OCT4, SOX2, and Nanog genes in cloned cells were significantly higher than those in fibroblasts. The results of 0 d and 30 d transcriptom sequencing showed that 9,465 differentially expressed genes were annotated to the GO database, of which 6,987 were up-regulated and 2,478 were down-regulated. The KEGG analysis had a total of 5,773 genes annotated to 259 pathways, of which the P53 signaling pathway was significantly enriched. What happened here played a very important role in stem cell proliferation.【Conclusion】The above results suggest that ovine induced pluripotent stem cells have been successfully established, which had laid the foundation for further study and application of ovine induced pluripotent stem cells.
