Project description:Naïve human pluripotent stem cells (hPSCs) provide a unique experimental platform of cell fate decisions during pre-implantation development, but their lineage potential remains incompletely characterized. As naïve hPSCs share transcriptional and epigenomic signatures with trophoblast cells, it has been proposed that the naïve state may have enhanced predisposition for differentiation along this extraembryonic lineage. Here we examined the trophoblast potential of isogenic naïve and primed hPSCs. We found that naïve hPSCs can directly give rise to human trophoblast stem cells (hTSCs) and undergo further differentiation into both extravillous and syncytiotrophoblast. In contrast, primed hPSCs do not support hTSC derivation, but give rise to non-self-renewing cytotrophoblasts in response to BMP4. Global transcriptome and chromatin accessibility analyses indicate that hTSCs derived from naïve hPSCs acquire features of pre-implantation trophectoderm. The derivation of hTSCs from naïve hPSCs will enable elucidation of early mechanisms that govern normal human trophoblast development and associated pathologies.

Project description:A limited number of accessible and representative models of human trophoblast cells currently exist for disease modeling and improving our understanding of placentation. Current stem cell models involve either a transition through a naïve stem cell fate or precise dynamic control of multiple interacting growth factor and small molecule cues. Here, we show that simple exposure of hiPSCs to two small molecules, retinoic acid (RA) and the Wnt signaling agonist CHIR 99021 (CHIR), results in rapid, synergistic upregulation of CDX2, an important transcription factor for trophectoderm cell induction and maintenance of the trophoblast cell population. RA+CHIR-treated cells have a transcriptional profile with high similarity to that of primary trophectoderm cells, and they can also be further differentiated into cells with features of syncytiotrophoblasts and extravillous trophoblasts. We assessed RA+CHIR-treated cells for the established set of criteria defining a trophectoderm cell model, and the cells possess all of the features necessary to be considered a valid model. Taken together, our data demonstrate the development of a simple method for the generation of functional trophoblast-like cells that can be used to better understand mechanisms and interactions involving the placenta.

Project description:In human, the functional placenta requires the proper differentiation of trophoblastic subtypes from the trophoblast stem cells (hTSCs). Although successful derivation of hTSCs from the early placentas and blastocysts, these hTSCs face ethical concerns and limited models for trophoblast-related disorders at later stage, such as preeclampsia. Here, we show that both hESCs and hiPSCs are able to be induced to the long-term and proliferative hTSCs under defined culture medium. These induced trophoblast stem cells (iTSCs) are comparable to the hTSC cell line derived from blastocyst in morphology, growth properties, specific genes expression, capacity of differentiating toward extravillous cytotrophoblast and syncytiotrophoblast, and patterns of transcriptome profile, chromatin accessibility and histone modification that are conducive to placenta development and maintenance of hTSCs. Notably, iTSCs meet four criteria defining "trophoblastic" including: expression of specific transcript factors, hypomethylation of ELF5 promoter, lack of expression of HLA-class I molecules and expression of the chromosome 19-encoded miRNA. Moreover, we reveal that addition of BMP4 or absence of H3K27 methyltransferases EZH1/2 could enhance the iTSCs generation. Our results suggest that human TS cells could be derived from human pluripotent stem cells, which expands the source of human TS cells avoiding ethic issues and provides a useful tool for researching placenta development and function, and modeling placenta-originated disorders.
