Somatic cells can be reprogrammed into induced pluripotent stem cells (iPSCs) through epigenetic manipulation. While the essential role of miRNA in reprogramming and maintaining pluripotency is well studied, little is known about the functions of miRNA from exosomes in this context. To fill this research gap,we comprehensively obtained the 17 sets of cellular mRNA transcriptomic data with 3.93 × 10bp raw reads and 18 sets of exosomal miRNA transcriptomic data with 2.83 × 10bp raw reads from three categories of human somatic cells: peripheral blood mononuclear cells (PBMCs), skin fibroblasts(SFs) and urine cells (UCs), along with their derived iPSCs. Additionally, differentially expressed molecules of each category were identified and used to perform gene set enrichment analysis. Our study provides sets of comparative transcriptomic data of cellular mRNA and exosomal miRNA from three categories of human tissue with three individual biological controls in studies of iPSCs generation, which will contribute to a better understanding of donor cell variation in functional epigenetic regulation and differentiation bias in iPSCs.
体细胞可通过表观遗传操作重编程为诱导多能干细胞(iPSCs)。miRNA 在重编程和维持多能性中的重要作用已得到充分研究,但对于外泌体 miRNA 在这方面的功能知之甚少。为了填补这一研究空白,我们从外周血单核细胞(PBMCs)、皮肤成纤维细胞(SFs)和尿细胞(UCs)这三种人类体细胞以及它们衍生的 iPSCs 中,全面获得了 17 组细胞 mRNA 转录组数据和 18 组外泌体 miRNA 转录组数据,每组数据分别有 3.93×10bp 原始读长和 2.83×10bp 原始读长。此外,还鉴定了每个类别的差异表达分子,并用于进行基因集富集分析。我们的研究提供了从三种人类组织来源的三种个体生物对照的细胞 mRNA 和外泌体 miRNA 的比较转录组数据集,这将有助于更好地理解 iPSCs 生成过程中供体细胞在功能表观遗传调控和分化偏倚方面的差异。
