Project description:We explored the trophoblast differentiation model using human induced pluripotent stem cells (hiPSCs) to gain new insights into the early development of human placenta. In our previous study, we have optimized culture conditions for hiPSC-derived trophoblasts. To identify the characteristics of trophoblast lineage cells derived from BMP4-treated hiPSCs, we collected cells using a pan-trophoblast marker, KRT7, with flow cytometry and performed comprehensive gene expression analysis.

Project description:Trophoblast differentiation from human ESC has been achieved by exposing the cells to BMP4 with or without supplementation of ALK4/5/7 inhibitor (A83-01) and FGF2 signaling inhibitor (PD173074) (BAP). Here the two differentiation conditions, BMP4 and BAP were applied to two sets of human PSC lines, H1 ESC and iPSC that latter was generated by DOX-inducible lentiviral (V) transductions of umbilical cord mesenchymal cells. The V-iPSC showed residual transgene expressions from the viral vectors in DOX-free culture condition. When the both ESC and iPSC lines were differentiated simultaneously, similar time dependent morphological changes were observed but BMP4 treated V-iPSC showed a minor yet consistent lag in the differentiation progression compared to BMP4 treated hESC. Although both differentiated ESC and V-iPSC showed dominant trophoblast phenotypes, the BMP4 treated V-iPSC also expressed gene markers consistent with the presence of mesoendoderm. The BAP condition provided more efficient differentiation than BMP4 alone, and the BAP-differentiated iPSC and ESC never expressed mesoendoderm markers. Five samples, one control of undifferentiated V-iPSC (FGF2) and four differentiated samples included two H1 ESC (treated with BMP4 or BMP4+A83-01) and similarly treated two V-iPSC were analyzed. Trophoblast differentiation was conducted with BMP4 (10 ng/ml) with or without supplementation of ALK4/5/7 inhibitor (A83-01; 1 μM) to H1 ESC and V-iPSC, respective reagents were added to FGF2-free MEF-CM from the second day culture of following passages for up to six additional days.

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:Trophoblast is the primary epithelial cell type in the placenta, a transient organ required for proper fetal growth and development. We have identified a CDX2+/p63+ cytotrophoblast (CTB) subpopulation in the early post-implantation human placenta, which is significantly reduced later in gestation. CTB differentiate into different trophoblast subtypes, which are responsible for gas/nutrient exchange (syncytiotrophoblast/STB) and invasion and maternal vascular remodeling (extravillous trophoblast/EVT). Study of early human placental development is severely hampered by lack of a representative trophoblast stem cell (TSC) model, with the capacity for self-renewal and the ability to differentiate into both STB and EVT. We describe a reproducible protocol, using defined media containing BMP4, by which human embryonic stem cells (hESC) can be differentiated into CDX2+/p63+ CTB-like cells. These cells can be replated to further differentiate into STB- and EVT-like cells, based on marker expression, hormone secretion and invasive ability. Differentiation of hPSC-derived CTB in hypoxia leads to reduced hCG secretion and STB-associated gene expression, instead inducing EVT differentiation in a hypoxia-inducible factor-dependent manner. Human embryonic stem cells (hESC) (WA09/H9) were maintained on Geltrex-coated plates (BD Biosciences ) in StemPro (Thermo Fisher) + bFGF (12 ng/ml). Undifferentiated hESC (D-2) were switched to minimal media (EMIM (Erb et al., 2011) containing KO DMEM/F12 (Gibco), 1% Insulin-Transferrin-Selenium Mix (Sigma-Aldrich), 1% NEAA (Gibco), 2mM L-Glutamine (Corning), 0.1mM 2-mercaptoethanol (Gibo), and 2% BSA (Gemini Bio Products)) for 2 days then treated with BMP4 (StemRD, 10ng/ml) for 3 days in minimal media+BMP4 (D3). At D3, cells were replated onto Geltrex in Feeder Conditioned Media +BMP4 and cultured in normoxia (20% O2) or hypoxia (2% O2) for 2 days (D3+2) to assess the effect of hypoxia. Cells were infected with lentiviral shRNA for shScramble (control) or shARNT, the beta subunit of the Hypoxia Inducible Factor (HIF) complex to assess the effect of ARNT knockdown. Each sample includes biological triplicates.

Project description:Human pluripotent stem cells (hPSC) exposed to BMP4 (B) and inhibitors of ACTIVIN signaling (A83-01; A) and FGF2 (PD173074; P) in absence of FGF2 (BAP conditions) differentiate into colonies primarily comprised of trophoblast. In an attempt to isolate trophoblast stem cells, colonies of hESC were exposed to BAP for 24 h at which time they had begun to transition into a CDX2-positive state. Cultures were then dissociated into single cells by trypsin and grown on a gelatin substratum. Under these conditions, organized CDX2+/KRT7- colonies began to emerge within a few days. The self-renewing cell lines were not TBSC, but met standard criteria for pluripotency. They were named H1BP cells. They differed from the progenitor hPSC in morphology, ability to be clonally propagated from single cells onto gelatin, requirements for FGF2, and transcriptome profile.

Project description:The excitement and controversy surrounding the potential role of human embryonic stem (ES) cells in transplantation therapy have often overshadowed their potentially more important use as a basic research tool for understanding the development and function of human tissues. Human ES cells can proliferate without a known limit and can form advanced derivatives of all three embryonic germ layers. What is less widely appreciated is that human ES cells can also form the extra-embryonic tissues that differentiate from the embryo before gastrulation. The use of human ES cells to derive early human trophoblast is particularly valuable, because it is difficult to obtain from other sources and is significantly different from mouse trophoblast. Here we show that bone morphogenetic protein 4 (BMP4), a member of the transforming growth factor-beta (TGF-beta) superfamily, induces the differentiation of human ES cells to trophoblast. DNA microarray, RT-PCR, and immunoassay analyses demonstrate that the differentiated cells express a range of trophoblast markers and secrete placental hormones. When plated at low density, the BMP4-treated cells form syncytia that express chorionic gonadotrophin (CG). These results underscore fundamental differences between human and mouse ES cells, which differentiate poorly, if at all, to trophoblast. Human ES cells thus provide a tool for studying the differentiation and function of early human trophoblast and could provide a new understanding of some of the earliest differentiation events of human postimplantation development.

Project description:During implantation, the blastocyst trophectoderm attaches to the endometrial epithelium and continues to differentiate into all trophoblast subtypes, which are the major components of a placenta. Aberrant trophoblast proliferation and differentiation are associated with placental diseases. However, due to ethical and practical issues, there is almost no available cell or tissue source to study the molecular mechanism of human trophoblast differentiation, which further becomes a barrier to the study of the pathogenesis of trophoblast-associated diseases of pregnancy. In this study, our goal was to generate a proof-of-concept model for deriving trophoblast lineage cells from induced pluripotency stem (iPS) cells from human fibroblasts. In future studies the generation of trophoblast lineage cells from iPS cells established from patient's placenta will be extremely useful for studying the pathogenesis of individual trophoblast-associated diseases and for drug testing.Combining iPS cell technology with BMP4 induction, we derived trophoblast lineage cells from human iPS cells. The gene expression profile of these trophoblast lineage cells was distinct from fibroblasts and iPS cells. These cells expressed markers of human trophoblasts. Furthermore, when these cells were differentiated they exhibited invasive capacity and placental hormone secretive capacity, suggesting extravillous trophoblasts and syncytiotrophoblasts.Trophoblast lineage cells can be successfully derived from human iPS cells, which provide a proof-of-concept tool to recapitulate pathogenesis of patient placental trophoblasts in vitro.
