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

ABSTRACT: 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.

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

Project description: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.

The Long Noncoding RNA Lncenc1 Regulates Glycolysis in Naive Mouse ES Cells II

Project description:The naive embryonic stem cells (nESCs) display unique characteristics mirroring naive pluripotency in vivo, but the molecular mechanisms underlying the self-renewal of nESCs remain incompletely understood. Here we analyzed stranded transcriptomes in mouse nESCs and epiblast-like cells (EpiLCs), and identified 135 long non-coding RNAs (lncRNAs) preferentially expressed in nESCs. We further investigated the functions of Lncenc1, a highly abundant lncRNA in mouse nESCs. Knockdown or knockout of Lncenc1 in mouse nESCs leads to significantly decreased expression of core pluripotency genes and significant reduction of colony formation capability. Furthermore, depletion of Lncenc1 down-regulates the glycolysis pathway, as indicated by significant decreases of glycolysis genes expression, glucose consumption, lactate production and Seahorse data. Mechanically, Lncenc1 associates with RNA-binding proteins PTBP1 and HNRNPK functionally. Together, we demonstrate that Lncenc1 regulates the glycolysis in mouse nESCs, suggesting novel functions of lncRNAs in linking energy metabolism and pluripotent stem cells.

Amplification of Germ Cells through Parthenogenesis Faithfully Maintain Genomic Imprinting [RRBS]

Project description:We asked whether oocyte number could be amplified through parthenogenesis of mouse oocytes, without requiring creation of a paternal genome and a genetically unique genome. Parthenotes develop to a blastocyst-like stage, and from this parthenogenetic ESCs (pESCs) can be derived with high efficiency. Like ESCs, pESCs maintain unlimited self-renewal and pluripotency, as well as germline competence. Further, we demonstrate that their expression pattern of imprinted maternal genes resembles that observed in oocytes. pESCs can be directed to differentiate into primordial germ cell-like cells (PGCLCs) and form oocytes that produce fertile pups and reconstitute ovarian endocrine functions. The transcriptome and imprinting pattern of PGCLCs differentiated from pESCs more closely approximate those of in vivo produced embryonic PGCs, than PGCLCs produced from ESCs. Parthenogenesis offers a promising route for deriving PGCLCs and amplifying oocytes by faithfully maintaining maternal genes, without fertilization.
