Specifying the Anterior Primitive Streak by Modulating YAP1 Levels in Human Pluripotent Stem Cells

Project description:Specifying the primitive streak (PS) guides stem cell differentiation in vitro, however much remains to be learned about the transcription networks that direct anterior and posterior PS cells (APS and PPS, respectively) to differentiate to distinct mesendodermal subpopulations. Here, we show that APS genes are predominantly induced in YAP1-/- hESCs in response to ACTIVIN. This finding establishes the Hippo effector YAP1 as a master regulator of PS specification, functioning to repress ACTIVIN-regulated APS genes in hESCs. Moreover, transient exposure of wild-type hESCs to dasatinib, a potent C-SRC/YAP1 inhibitor, enables differentiation to APS-derived endoderm and cardiac mesoderm in response to ACTIVIN. Importantly, these cells can differentiate efficiently to normal beating cardiomyocytes without the cytoskeletal defect seen in YAP1-/- hESC-derived cardiomyocytes. Overall, we uncovered an induction mechanism to generate APS cells using a cocktail of ACTIVIN and YAP1i molecules that holds practical implications for hESC and iPSC differentiation into distinct mesendodermal lineages.

Expression Profile of Chicken Primitive Streak (HH4) Tissues

Project description:In birds and mammals, all mesoderm cells are generated from the primitive streak. Nascent mesoderm cells contain unique dorso-ventral (D/V) identities depending on their relative ingression position along the streak. Molecular mechanisms controlling this initial phase of mesoderm diversification are not well-understood. Using chick model, we generated high-quality transcriptomic datasets of different streak regions and analyzed their molecular heterogeneity. Streak tissues were dissected from stage-matched HH4 chick embryos and were further divided into four equal pieces along its anterio-posterior length (termed “A”, “B”, “C” and “D”, with “A” representing most anterior and therefore most dorsal and “D” most posterior and therefore most ventral). Each of the four regions was represented by three independent samples (n=3), with each sample containing 5-7 μg total RNA derived from 85-93 pooled pieces. 5 μg of RNA from each sample were used to screen Affymetrix Chicken Genome Array without an amplification step.

Induction of pluripotency in human somatic cells via a primitive streak-like state

Project description:During mammalian embryonic development, the primitive streak is initiates the differentiation of pluripotent epiblast cells into germ layers. Pluripotency can be reacquired in committed somatic cells using a combination of handful transcription factors, such as OCT3/4, SOX2, KLF4 and c-MYC (hereafter referred to as OSKM), albeit with low efficiency . Here we show that, during the OSKM-induced reprogramming process toward pluripotency in human cells, intermediate cells transiently show gene expression profiles resembling mesendoderm, which is a major component of the primitive streak. Based on these findings, we discover that forkhead box H1 (FOXH1), a transcription factor required for anterior primitive streak specification during early development, significantly enhances the reprogramming efficiency of human fibroblasts by promoting their maturation, including the mesenchymal to epithelial transition and the activation of late pluripotent markers. These results demonstrate that during the reprogramming process, human somatic cells go through a transient state that resembles mesendoderm.

PI3Kβ and β-Catenin mediate EZH2 removal from promoters controlling human ESC stemness and primitive streak gene expression

Project description:The mechanism governing the transition of human embryonic stem cells towards differentiated cells is only partially understood. To explore this transition, the activity and expression of the ubiquitous phosphoinositide-3-kinase (PI3K α and β) were modulated. This study reports a pathway that dismantles the repression imposed by the EZH2 polycomb repressor on an essential stemness gene, NODAL, and on transcription factors required at differentiation to trigger primitive streak formation. The primitive streak is the site where gastrulation begins to give rise to the three embryonic cell layers from which all human tissues derive. The pathway involves an essential PI3Kβ-non-catalytic action for control of active-RAC1 levels, c-Jun-Nterminal-kinase activation and nuclear β-CATENIN accumulation. β-CATENIN deposition at promoters triggers the release of EZH2 repressor permitting both stemness maintenance (through control of NODAL) and correct differentiation, by allowing primitive streak master genes expression. PI3Kβ -mediated epigenetic control of EZH2/β-CATENIN might be modulated to direct stem cell differentiation.
