Global transcriptional analysis of human extended pluripotent stem cells, human primed pluripotent stem cells, mouse extended pluripotent stem cells, and mouse embryonic stem cells by RNA-seq

ABSTRACT: All mammals develop from embryonic founder cells with the ability to generate all of the differentiated cells that constitute the organism. Capture of stem cells with such developmental potential in vitro has been a major challenge in stem cell biology. Here, we show that a chemical cocktail enables the derivation of a new stem cell type from both mice and humans, designated as extended pluripotent stem (EPS) cells. A single human or mouse EPS cell is able to contribute to both embryonic and extraembryonic lineages in inter- and intra-species chimeric mouse conceptuses respectively. Compared to known pluripotent stem cells, EPS cells show upregulation of gene modules marking embryonic cells from early preimplantation development. Further analysis shows that PARP1 inhibition is required for maintaining EPS potency. Our findings constitute a first step towards capturing authentic mammalian totipotency in vitro, and open new avenues for basic and translational research.

Genome-wide analysis of chromatin state in extended pluripotent stem cells, primed pluripotent stem cells, and naïve pluripotent stem cells

Project description:Among all known cultured stem cell types, pluripotent stem cells (PSCs) sit atop the landscape of developmental potency and are characterized by their unrestricted developmental potential, able to generate all cell types of an adult organism. However, PSCs show limited contribution to the extraembryonic (ExEm) tissues, in particular, those giving rise to the placenta in vivo. To date, it remains unknown whether stem cells with both embryonic and extraembryonic developmental potency can be captured and maintained in vitro. Here, we identify a new chemical cocktail that allows for the generation of stem cells with extended developmental potency from mouse and human, designated as extended pluripotent stem (EPS) cells, which is capable of chimerizing both embryonic and extraembryonic tissues. Importantly, a single mouse EPS (mEPS) cell shows widespread contribution to both embryonic and extraembryonic lineages in chimeric mouse conceptuses at late-gestation stages, and permits generation of high-grade germline competent chimeras as well as single EPS-derived viable mice by tetraploid complementation. Furthermore, human EPS (hEPS) cells contribute to embryonic and extraembryonic tissues in interspecies chimeric mouse conceptuses. Compared to known PSCs, EPS cells show unique gene modules that upregulate in embryonic cells from early preimplantation development. Further analysis shows that PARP1 inhibition is required for maintaining EPS potency. Our findings constitute a first step towards capturing pluripotent stem cells with extraembryonic developmental potentials in culture, and open new avenues for generating mammalian PSCs with robust chimeric competency for basic and translational research.

Generation of functional hepatocytes from extended pluripotent stem cells

Project description:We established efficiently differentiation protocol of human extented pluripotent stem (EPS) cells to functional hepatocytes (EPS-Heps) by simply adding a pre-treatment step before applying the directed differentiation protocol for conventional human pluripotent stem cells. Importantly, compared to hepatocytes derived from conventional human pluripotent stem cells, EPS-Heps transcriptionally more resemble primary human hepatocytes.

Generation of Blastocyst-like Structures from Extended Pluripotent Stem Cells

Project description:A single mouse blastomere from until 8-cell embryo can generate an entire blastocyst. Whether blastomere-like extended pluripotent stem cells (EPS cells) retain a similar generative capacity remains unknown. Here, we established a 3D differentiation system that enabled the generation of blastocyst-like structures from EPS cells (EPS-blastoids) through lineage segregation and self-organization. EPS-blastoids resembled blastocysts in morphology and cell lineage allocation. EPS-blastoids formation recapitulated key morphogenetic events during preimplantation and early postimplantation development in vitro. Upon transfer, some EPS-blastoids underwent implantation, induced decidualization, and generated live, albeit disorganized, tissues in utero. Single cell and bulk RNA-sequencing analysis revealed that EPS-blastoids contained all three blastocyst cell lineages and shared transcriptional similarity with natural blastocysts. We also provide proof-of-concept that EPS-blastoids can be generated from somatic cells via cellular reprograming. EPS-blastoids provide a unique platform for studying early embryogenesis, and pave the way to generate viable synthetic embryos using cultured cells.

Chromatin accessibility of xeno-free and feeder-cultured human extended pluripotent stem cells by ATAC-seq

Project description:Extended pluripotent stem (EPS) cells have shown great applicative potentials in generating synthetic embryos, directed differentiation and disease modeling. However, the lack of a xenofree culture condition has significantly limited their wide applications. We developed a chemically defined and xeno-free culture condition for culturing and deriving human EPS cells, which can be long-term stably propagated in vitro, as well as preserve their embryonic and extraembryonic developmental potentials.

Recapitulating human peri-gastrulation development via self-organization of extended pluripotent stem cells

Project description:Stem cell models that replicate the gastrulation process in human embryos have been created, but they lack the essential extraembryonic cells needed for early embryonic development and patterning. Here, we introduce a robust and efficient method that prompts human extended pluripotent stem (EPS) cells to self-organize into embryo-like structures, called peri-gastruloids, which encompass both embryonic (epiblast) and extraembryonic (hypoblast) tissues. These peri-gastruloids simulate critical stages of human peri-gastrulation development, such as forming amniotic and yolk sac cavities, developing bilaminar and trilaminar embryonic discs, specifying primordial germ cells, initiating gastrulation, and early neurulation. Single-cell RNA sequencing unveiled transcriptomic characteristics of these human peri-gastruloids, which closely resemble the primary peri-gastrulation cell types found in human and non-human primates. Our results emphasize the remarkable self-organizing ability of EPS cells to generate advanced human embryo-like structures. This peri-gastruloid platform allows for further exploration beyond gastrulation and may potentially aid in the development of human fetal tissues for use in regenerative medicine.
