Dynamic developmental signaling logic underlying lineage bifurcations during human endoderm induction and patterning from pluripotent stem cells [Endoderm RNA-seq and ChIP-seq data sets]

ABSTRACT: Unraveling complex signaling programs animating developmental lineage-decisions is pivotal to differentiate human pluripotent stem cells (hPSC) into pure populations of desired lineages for regenerative medicine. Developmental signals are strikingly temporally dynamic: BMP and Wnt initially specify primitive streak (progenitor to endoderm) yet 24 hours later suppress endoderm and induce mesoderm. At lineage bifurcations we show mutually-exclusive embryonic lineages are segregated through cross-repressive signals: TGFβ and BMP/MAPK duel to respectively specify pancreas versus liver from endoderm. Unilateral endodermal differentiation requires blockade of alternative fates at every stage, revealing a universal developmental strategy for efficient differentiation and anterior-posterior patterning of diverse hPSC lines into highly-pure endodermal populations. This culminated in hPSC-derived hepatic progenitors that, for the first time, engraft long-term in genetically-unconditioned mouse livers and secrete human albumin. Finally, thirty transcriptional and chromatin state maps capturing endoderm commitment revealed endodermal enhancers reside in an unanticipated diversity of "pre-enhancer" chromatin states before activation.

Efficient derivation of purified lung and thyroid progenitors from embryonic stem cells

Project description:Two populations of Nkx2-1+ progenitors in the developing foregut endoderm give rise to the entire post-natal lung and thyroid epithelium, but little is known about these cells, as they are difficult to isolate in a pure form. We demonstrate here the purification and directed differentiation of primordial lung and thyroid progenitors derived from mouse embryonic stem cells (ESCs). Inhibition of TGFβ and BMP signaling, followed by combinatorial stimulation of BMP and FGF signaling can specify these cells efficiently from definitive endodermal precursors. When derived using Nkx2-1GFP knock-in reporter ESCs, these progenitors can be purified for expansion in culture and have a transcriptome that overlaps with developing lung epithelium. Upon induction, they can express a broad repertoire of markers indicative of lung and thyroid lineages and can recellularize a 3D lung tissue scaffold. Thus, we have derived a pure population of progenitors able to recapitulate the developmental milestones of lung/thyroid development.

Mouse embryonic and induced pluripotent stem cells can form definitive endoderm despite differences in imprinted genes

Project description:The directed differentiation of induced pluripotent stem (iPS) and embryonic stem (ES) cells into definitive endoderm (DE) would allow the derivation of otherwise inaccessible progenitors for endodermal tissues. However, a global comparison of the relative equivalency of DE derived from iPS and ES populations has not been performed. Recent reports of molecular differences between iPS and ES cells have raised uncertainty as to whether iPS cells could generate autologous endodermal lineages in vitro. Here, we have shown that both mouse iPS and parental ES cells exhibited highly similar in vitro capacity to undergo directed differentiation into DE progenitors. With few exceptions, both cell types displayed similar surges in gene expression of specific master transcriptional regulators and global transcriptomes that define the developmental milestones of DE differentiation. Microarray analysis showed considerable overlap between the genetic programs of DE derived from ES/iPS cells in vitro and authentic DE from mouse embryos in vivo. Intriguingly, iPS cells exhibited aberrant silencing of imprinted genes known to participate in endoderm differentiation, yet retained a robust ability to differentiate into DE. Our results show that, despite some molecular differences, iPS cells can be efficiently differentiated into DE precursors, reinforcing their potential for development of cell-based therapies for diseased endodermal-derived tissues.

Generation of pancreatic β cells from CD177+ anterior definitive endoderm

Project description:Methods for differentiating human pluripotent stem cells to pancreatic and liver lineages in vitro have been limited by the inability to identify and isolate distinct endodermal subpopulations specific to these two organs. Here we report that pancreatic and hepatic progenitors can be isolated using the surface markers CD177/NB1 glycoprotein and inducible T-cell costimulatory ligand CD275/ICOSL, respectively, from seemingly homogeneous definitive endoderm derived from human pluripotent stem cells. Anterior definitive endoderm (ADE) subpopulations identified by CD177 and CD275 show inverse activation of canonical and noncanonical WNT signaling. CD177+ ADE expresses and synthesizes the secreted WNT, NODAL and BMP antagonist CERBERUS1 and is specified toward the pancreatic fate. CD275+ ADE receives canonical Wnt signaling and is specified toward the liver fate. Isolated CD177+ ADE differentiates more homogeneously into pancreatic progenitors and into more functionally mature and glucose-responsive β-like cells in vitro compared with cells from unsorted differentiation cultures.

The emergent landscape of the mouse gut endoderm at single-cell resolution

Project description:To comprehensively delineate the ontogeny of an organ system, we generated 112,217 single- cell transcriptomes representing all endoderm populations within the mouse embryo until midgestation. We employed graph-based approaches to model differentiating cells for spatio- temporal characterization of developmental trajectories. Our analysis reveals the detailed architecture of the emergence of the first (primitive or extra-embryonic) endodermal population and pluripotent epiblast. We uncover an unappreciated relationship between descendants of these lineages, before the onset of gastrulation, suggesting that mixing of extra-embryonic and embryonic endoderm cells occurs more than once during mammalian development. We map the trajectories of endoderm cells as they acquire embryonic versus extra-embryonic fates, and their spatial convergence within the gut endoderm; revealing them to be globally similar but retaining aspects of their lineage history. We observe the regionalized localization of cells along the forming gut tube, reflecting their extra-embryonic or embryonic origin, and their coordinate patterning into organ-specific territories along the anterior-posterior axis.

Conversion of Gastric Epithelia to Endoderm Progenitors by Small Molecules [gene expression]

Project description:Forced expression of transcription factors for lineage reprogramming brings hope to cell-based therapy. However, its application is hampered by risks of potential genetic aberrations and tumorigenicity. Using defined small molecules in presence of gastric stromal cells as feeders, we reprogramed human gastric epithelia into induced multipotent endodermal progenitors (hiMEPs) with efficiency of up-to-6%. The hiMEPs expressed genes relative to endodermal lineages but not associating with pluripotency, and could be expanded clonogenically remaining as undifferentiated colonies. Upon induction, hiMEPs were able to give rise to multiple functional endodermal cell types, apart from ectodermal or mesodermal lineages. TGFÎ² inhibition and particular Wnt signaling activation were crucial in reprogramming process. Collective advantages of availability from donors without age restriction, capabilities in expansion and differentiation, and no concern of tumorigenesis, let hiMEPs have the considerable application potentials on cell therapies of diseases such as liver failure and diabetes, as well as personalized drug-screenings. Gastric epithelial cells (GECs) were isolated from human stomach. Human induced multipotent endodermal progenitors (hiMEPs) were reprogrammed from GECs by small molecules. The hiMEP-Heps were differentiated from hiMEPs under hepatic differentiation protocol. Fetal-Heps were isolated from aborted fetal liver. Definitve endoderm (DE), primitive gut tube (PGT), and posterior foregut (PFG) were endodermal stem cells derived form human enbryonic stem cells (hESCs).We used RNA sequencing and DNA methylation analysis to detail the global gene expression profile of GECs, hiMEPs, hiMEP-Heps, Fetal-Heps, DE, PGT and PFG to delineate the difference of these cells.

Expression profile of human ESC, ESC-drived definitive endoderm and endodermal progenitor cells

Project description:Endodermal progenitor cells (EP cells) are derived from human embryonic stem cell(ESC)-derived definitive endoderm (DE) cells. EP cells are cultured in high BMP media and DE cells are in high Activin media. Both cells can be further differentiated to liver, pancreas, etc. We used microarray to detail the global gene expression profile of DE cells and EP cells to delineate the difference of DE cells and EP cells. ESCs were sorted by SSEA3 and SSEA4. DE cells and EP cells were sorted by CXCR4 and CD117. Sorted cells were lysed in RLT buffer. RNA was extracted and hybridized to Affimetrix microarrays. Each group had 3 biological replicates.
