Pluripotent stem cells hold great investigative potential for developmental biology and regenerative medicine. Recent studies suggest that long noncoding RNAs (lncRNAs) may function as key regulators of the maintenance and the lineage differentiation of stem cells. However, the underlying mechanisms by which lncRNAs affect the reprogramming process of somatic cells into pluripotent cells remain largely unknown. Using fibroblasts and induced pluripotent stem cells (iPSCs) at different stages of reprogramming, we performed RNA transcriptome sequencing (RNA-Seq) to identify lncRNAs that are differentially-expressed in association with pluripotency. An RNA reverse transcription-associated trap sequencing (RAT-seq) approach was then utilized to generate a database to map the regulatory element network for lncRNA candidates. Integration of these datasets can facilitate the identification of functional lncRNAs that are associated with reprogramming. Identification of lncRNAs that regulate pluripotency may lead to new strategies for enhancing iPSC induction in regenerative medicine.
多能干细胞在发育生物学和再生医学方面具有巨大的研究潜力。最近的研究表明,长非编码 RNA(lncRNA)可能作为干细胞的维持和谱系分化的关键调节因子发挥作用。然而,lncRNA 影响体细胞重编程为多能细胞的过程的潜在机制在很大程度上仍是未知的。我们使用不同重编程阶段的成纤维细胞和诱导多能干细胞(iPSC),进行了 RNA 转录组测序(RNA-Seq),以鉴定与多能性相关的差异表达的 lncRNA。然后利用 RNA 逆转录相关的陷阱测序(RAT-seq)方法生成一个数据库,以绘制 lncRNA 候选物的调控元件网络。整合这些数据集可以促进与重编程相关的功能 lncRNA 的鉴定。鉴定调节多能性的 lncRNA 可能为再生医学中增强 iPSC 诱导提供新的策略。
