Integrative analysis of reprogramming human fibroblast cells to naïve pluripotency [RNA-seq]

ABSTRACT: Derivation of human naïve cells in the ground state of pluripotency provides promising avenues for developmental studies and therapeutic manipulations. However, the molecular mechanisms involved in establishment and maintenance of human naïve pluripotency remain poorly understood. Using the human inducible reprogramming system together with 5iLAF naïve induction strategy, we performed integrative analysis across the timeline from human fibroblasts to naïve iPSCs, which reveals ordered expression waves of gene networks sharing signatures with embryonic development process from post-implantation to pre-implantation stages. We also observed a significant transient re-activation of transcripts with 8-cell-stage-like characteristics in late naïve reprogramming stages. Moreover, combined quantitative proteomics analysis with transcriptional dynamics during naïve pluripotency induction, we identified ALPPL2 as the specific surface marker for human naïve pluripotency. Altogether, our study deepens the understanding of molecular mechanisms of human naïve pluripotency.

Integrative analysis of reprogramming human fibroblast cells to naïve pluripotency [RRBS]

Identification of ALPPL2 as a novel specific and functional surface marker for naïve pluripotency

Project description:We report ALPPL2 as a prominently specific and functional surface marker for naïve pluripotency. By performing RNA-seq analysis of TJ-1# and iCRISPR nESCs and pESCs, APG+ cells at different time points during naïve reprogramming, we validate ALPPL2’s specificity for naïve pluripotent state at transcriptional level. Deep analysis of the transcriptome differences between Wild Type (WT), ALPPL2 knockdown (AKD) cells via RNA-seq, Wild Type (WT), ALPPL2 knockout (AKO) and IGFBP1 knockout (IKO) individual colonies in detail via Smart-seq, and performing RNA immunoprecipitation (RIP) using IGF2BP1 antibody in nESCs followed by RNA-seq or qPCR analysis, we identify that ALPPL2 is essential for both establishment and maintenance of naïve pluripotency via interacting with IGF2BP1 to stabilize TFCP2L1 and STAT3 mRNA level.

Tankyrase inhibition facilitates RNA-mediated reprogramming of human somatic cells to naïve pluripotency

Project description:In contrast to conventional human pluripotent stem cells (hPSC) that are related to post-implantation embryo stages, naïve hPSC exhibit features of pre-implantation epiblast. Naïve hPSC are established by resetting conventional hPSC, or are derived from dissociated embryo inner cell masses. Here we investigate conditions for transgene-free reprogramming of human somatic cells to naïve pluripotency. We find that RNA-mediated induction of naïve pluripotency is enhanced by Wnt inhibition. We demonstrate application to independent human fibroblast cultures and endothelial progenitor cells and show that induced naïve hPSC can be clonally expanded with a diploid karyotype. They exhibit distinctive surface marker, transcriptome, and methylome properties of naïve epiblast identity. Induced naïve hPSC lines undergo somatic lineage differentiation following formative transition. Efficient, facile, and reliable induction of transgene free naïve hPSC offers a robust platform for delineation of human reprogramming trajectories and for evaluating the attributes of isogenic naïve versus conventional hPSC.

Integrative analyses of human reprogramming reveal dynamic nature of induced pluripotency [shRNA]

Project description:Induced pluripotency is a promising avenue for disease modeling and therapy, but the molecular principles underlying this process, particularly in human cells, remain poorly understood due to donor-to-donor variability and intercellular heterogeneity. Here we constructed and characterized a clonal, inducible human reprogramming system that provides a reliable source of cells at any stage of the process. This system enabled integrative transcriptional and epigenomic analysis across the human reprogramming timeline at high resolution. We observed distinct waves of gene network activation, including the ordered re-activation of broad developmental regulators followed by early embryonic patterning genes and culminating in the emergence of a signature reminiscent of pre-implantation stages. Moreover, complementary functional analyses allowed us to identify and validate novel regulators of the reprogramming process. Altogether, this study sheds light on the molecular underpinnings of induced pluripotency in human cells and provides a robust cell platform for further studies.
