Pig pluripotent stem cells have tremendous potential because the pig is a valuable animal as both an agricultural resource and as a preclinical model of human therapy. To date, a lack of understanding of pig pluripotency has inhibited the derivation of embryonic stem cells (ESCs) and transgene-free induced pluripotent stem cells. Therefore, there has been no accessible or reliable transcriptome data for researching the genuine pig pluripotency network. Our previous study isolated authentic pig ESCs, which had teratoma-forming and direct differentiation ability, that were derived by activating the FGF2, ACTIVIN A, and WNT pathways. Here, we aimed to provide detailed information on transcriptome data of the newly derived pig ESCs and perform a comparative analysis with pig preimplantation embryo transcriptomes in a public database.
The transcriptome data of ESCs derived from in vitro fertilized and parthenogenetic embryos were generated by HiSeq 2500. Then, differentially expressed genes (DEGs) from each sample were compared with fibroblasts, and gene expression profiling was carried out for comparative analysis. Our data, as the first transcriptome dataset for genuine pig pluripotent cells, could be a general reference for explaining the molecular mechanism of species-specific pluripotency and improving understanding of the embryo development of domestic animals.
猪多能干细胞具有巨大潜力,因为猪作为农业资源和人类治疗的临床前模型都是一种有价值的动物。迄今为止,对猪多能性缺乏了解阻碍了胚胎干细胞(ESC)和无转基因诱导多能干细胞的获得。因此,目前尚无用于研究真正的猪多能性网络的可获取或可靠的转录组数据。我们之前的研究分离出了具有形成畸胎瘤和直接分化能力的真正猪ESC,这些细胞是通过激活FGF2、激活素A和WNT信号通路而获得的。在此,我们旨在提供新获得的猪ESC转录组数据的详细信息,并与公共数据库中的猪植入前胚胎转录组进行比较分析。
通过HiSeq 2500生成了来自体外受精和孤雌生殖胚胎的ESC转录组数据。然后,将每个样本的差异表达基因(DEG)与成纤维细胞进行比较,并进行基因表达谱分析以进行比较分析。我们的数据作为首个真正的猪多能细胞转录组数据集,可为解释物种特异性多能性的分子机制以及增进对家畜胚胎发育的理解提供通用参考。
