Project description:Derivation of naive state of mouse embryonic stem cells (mESCs) in LIF+serum (LS) culture condition is strain dependent, whereas derivation of ground state mESCs is readily possible from all strains tested so far in “2i” culture condition. ESCs can be derived from the post-implantation stage mouse embryos (EpiSCs), showing primed characteristics. In the present study, we characterized and compared the transcriptional profile of naïve, primed and ground state mESCs. Considering the importance of genetic background of mouse model for ESCs derivation in conventional culture conditions, all ESCs lines used in the study were derived from the same strain of mice. We found distinct transcriptional profiles between naive, primed and ground state mESCs. Primed state mESCs exhibit lower expression of pluripotency markers along with higher expression of lineage specific markers compared to naive and ground state mESCs. We also demonstrate that the differentiation propensity of ESCs to specific germ layer varies depending on the pluripotency state of ESCs.

Project description:We describe the global cell fate roadmap during primed-to-naive transition process by bulk mRNA-seq and ATAC-seq analysis among transition intermediates across different time points. We report that activation of ALPG is a landmark event for naive state establishment. Further investigation into transitioning cells with dynamic fluorescence presents intermediates branching into TE-like subpopulations with capacities of TSC derivation.

Project description:Here we propose a set of molecular criteria for evaluating the naive human pluripotent state. We show by RNA-seq that transcription of transposable elements provides a sensitive measure of the concordance between pluripotent stem cells and early human development. RNA-seq of 4 naive ES samples in 4i/LA, 3 naive ES samples in 5i/LA, 2 transgene-dependant naive ES cell samples, and 5 primed ES cell samples (in hESM)

Project description:The extent of naive characteriztics of recently reported naive human pluripotent stem cells (hPSCs) obtained in different naive-permissive media, is unclear. Moreover, these naive hPSCs were mainly derived by conversion from primed hPSCs or by direct derivation from human embryos rather than by somatic cell reprogramming. Here, we derived genetically matched human naive hPSCs by direct reprogramming of fibroblasts as well as primed-to-naive conversion using different naive conditions (NHSM, RSeT, 5iLAF and t2iLGöY). Comprehensive characterization showed that naive hPSCs obtained in these different conditions represent a spectrum of naive characteriztics irrespective of whether they were derived by conversion or reprograming. Importantly, only t2iLGöY hPSCs displayed a similar transcriptome to human cells from the inner cell mass, karyotypic stability and require re-priming for trilineage differentiation. Furthermore, our analyses identified KLF4 as a key reprogramming factor which enables conversion of primed hPSCs into naive t2iLGöY hPSCs. These findings underscore the role that reprogramming factors can play for the derivation of bona fide naive hPSCs and provide a molecular and functional reference for all the analysed conditions, which will help accelerate the downstream applications of naive hiPSCs.

Project description:Naive and primed human pluripotent stem cells (hPSC) provide valuable models to study cellular and molecular developmental processes. The lack of detailed information about cell-surface protein expression in these two pluripotent cell types prevents an understanding of how the cells communicate and interact with their microenvironments. Here, we used plasma membrane profiling to directly measure cell-surface protein expression in naive and primed hPSC. This unbiased approach quantified over 1700 plasma membrane proteins including those involved in cell adhesion, signalling and cell interactions. Notably, multiple cytokine receptors upstream of JAK-STAT signalling were more abundant in naive hPSC. In addition, functional experiments showed that FOLR1 and SUSD2 proteins are highly expressed at the cell surface in naive hPSC but are not required to establish human naive pluripotency. This study provides a comprehensive stem cell proteomic resource that uncovers differences in signalling pathway activity and has identified new markers to define human pluripotent states.

Project description:We have pioneered human pluripotent stem cell (hPSC) manufacturing in stirred suspension bioreactors. Cell therapies require large numbers of quality-controlled hPSCs yet technologies are limited in their ability to efficiently grow and scale clinically-viable hPSCs. We report here that naive hPSCs exhibit superior growth in suspension bioreactors compared to their primed counterpart. Naive hPSCs exhibited a shorter lag phase, and grew into more uniform, homogenous aggregates. Compared to static culture, gene expression analyses revealed that the bioreactor environment promoted the upregulation of naïve- and downregulation of primed-associated transcripts in both primed and naive hPSCs. Bioreactor-cultured naive hPSCs similarly showed more hypomethylated DNA and less primed hPSC-associated surface protein marker compared to statically-cultured naive hPSCs. Gene expression, epigenetic, and cell surface protein marker analyses all suggest that the bioreactor environment promotes the transition from primed-to-naive pluripotent state. Our research shows that reprogramming conventional hPSCs to the naive pluripotent state enhances hPSC manufacturing.

Project description:We introduce a method for generating transgene-free and high-quality naive human induced pluripotent stem cells (iPSCs) using a modified Sendai virus (SeV) vector reprogramming system. This reprogramming method realizes the derivation of naive iPSCs from various somatic cells accompanied with fast and robust SeV vector removal at early passages. The established naive iPSCs have superior naive-specific differentiation ability compared with iPSCs derived from conventional methods.
