Transcriptional profiles of embryonic stem cell derived gastrointestinal tissue.

Project description:Successful differentiation methods have been developed in several endodermal organs, including liver, pancreas, and intestine from embryonic stem cell and induced pluripotent stem cells. Compare to these organs, however, little has been known in gastric differentiation from embryonic stem cells. Here, we established a method of gastrointestinal tissue differentiation methods, including stomach regions from embryonic stem cells. These gastrointestinal tissue built gut primordium-like spheroids, which is also able to mature into adult tissue containing all differentiated cells in three-dimensional culture. These embryonic stem cells derived gastrointestinal tissue possessed the similar gene expression profile that of adult stomach. These data indicated that functional gastrointestinal tissue can be derived from embryonic stem cells by mimicking in vivo development and could be useful for investigating gastrointestinal study such as disease modeling.

Modelling Plasticity and Dysplasia of Pancreatic Ductal Organoids Derived from Human Pluripotent Stem Cells

Project description:Full protein measurements from in vitro differentiation of the human embryonic stem cell line HUES8 into pancreatic progenitors (PP) and pancreatic duct-like organoids (PDLOs). Protein intensities were quantified by mass spectrometry analysis from PPs at day 13 and from PDLOs at day 59. Please see related publication “Modelling Plasticity and Dysplasia of Pancreatic Ductal Organoids Derived from Human Pluripotent Stem Cells” for experimental details.

Metabolomic Profiling of Human Pluripotent Stem Cell Differentiation into Lung Progenitors

Project description:Metabolism is vital to cellular function and tissue homeostasis during human lung development. In utero, embryonic pluripotent stem cells undergo endodermal differentiation towards a lung progenitor cell fate that can be mimicked in vitro using induced human pluripotent stem cells (hiPSCs) to study genetic mutations. To identify differences between wild type and surfactant protein B (SFTPB)-deficient cell lines during endoderm specification towards lung, we used an untargeted metabolomics approach to evaluate the developmental changes in metabolites. We found that the metabolites most enriched during the differentiation from pluripotent stem cell to lung progenitor cell, regardless of cell line, were sphingomyelins and phosphatidylcholines, two important lipid classes in fetal lung development. The SFTPB mutation had no metabolic impact on early endodermal lung development. The identified metabolite signatures during lung progenitor cell differentiation may be utilized as biomarkers for normal embryonic lung development.

Comprehensive secretome and proteome analysis for human fetal brain self-organized organoids

Project description:To understand whether the intrinsic capacity of the fetal brain in vitro self-organizes into organoids (FeBOs) to secrete a tissue-like “matrisome” is linked to the maintenance of cell-to-cell organization and integrity, we compared the secretome of intact FeBOs and FeBO-derived neurospheres. We also performed side-by-side comparative proteomic analysis of FeBOs and human fetal brain tissue to investigate if the extracellular matrix (ECM) production in the FeBOs resembled a proper tissue-like ECM niche. Moreover, we also included proteomic analysis of unguided pluripotent stem cell (PSC)-cerebral organoids and PSC-cortical spheroids to understand how the human brain tissue ECM-niche compared not only to the FeBOs but also to PSC-derived 3D brain models.

Enrichment, proteome analysis and transplantation of human embryonic stem cell derived dopaminergic progenitors expressing LMX1a

Project description:Despite the progress in safety and efficacy of cell therapy with pluripotent stem cells (PSCs), the presence of residual undifferentiated stem cells or proliferating neural progenitor cells (NPCs) with rostral identity has remained a major challenge. Here we reported the generation of an LMX1A knock-in GFP reporter human embryonic stem cell (hESC) line that marks the early dopaminergic progenitors during neural differentiation. Purified GFP positive cells in vitro exhibited expression of mRNA and proteins that characterized and matched the midbrain dopaminergic identity. Further proteomic analysis of enriched LMX1A+ cells identified several membrane associated proteins including CNTN2, enabling prospective isolation of LMX1A+ progenitor cells. Transplantation of hPSC-derived purified CNTN2+ progenitors enhanced dopamine release from transplanted cells in the host brain and alleviated Parkinson’s disease symptoms in animal models. Our study establishes an efficient approach for purification of large numbers of hPSC-derived dopaminergic progenitors for therapeutic applications.

Compared gene expression profile of gastric and intestinal progenitors grown as spheroids in the ex vivo culture system

Project description:In adult stomach, Lgr5 is a marker of epithelial glandular stem cells that grow in the three dimensional ex vivo culture system as organoids. However, little is known about the markers that characterize fetal progenitors before cytodifferentiation and their potential involvement in regenerative processes in adults. Using the ex vivo culture system, we isolated epithelial progenitors from the fetal stomach. These cells generated stable undifferentiated immortal spheroids showing lower growth factor requirements as compared to the adult-type gastric Lgr5-expressing organoids. Although very similar in their gene expression profiles, cultured fetal gastric and intestinal spheroids differentially expressed Sox2/Cdx2 genes involved in regional pre-patterning. Accordingly, gastric but not intestinal spheroids, spontaneously converted into the cell lineages of the adult glandular stomach ex vivo. In vivo, the Trop2 marker enriched in the fetal gastric spheroids was transiently expressed in the gastric epithelium before cytodifferentiation while it remained barely detectable under glandular homeostasis in adults. However, upon specific ablation of the Lgr5 stem cell pool, highly proliferative Trop2-expressing cells rapidly emerged in the adult epithelium, qualifying Trop2 as a marker of Lgr5-independent gastric stem cells. Together, these data indicate that the Trop2 receptor identifies gastric fetal progenitors and adult stem/progenitor cells involved in regeneration of glandular stomach.

PDX1+ cell budding morphogenesis in a stem cell-derived islet spheroid system

Project description:Remarkable advancements in protocol development have been achieved to manufacture insulin-secreting islets from human pluripotent stem cells. Distinct from current approaches, we devised a tunable strategy to generate islet spheroids enriched for major islet cell types by incorporating PDX1+ cell budding morphogenesis into the differentiation process of staged transcriptional programming. In this process that appears to mimic normal islet morphogenesis, the differentiating islet spheroids self-organize with endocrine cells that are intermingled or arranged in a core-mantle architecture, accompanied with functional heterogeneity. Through in vitro modelling of human pancreas development, we illustrate the importance of PDX1 in eliciting cell budding morphogenesis, and the requirement for EphB3/4 signaling. We show how RFX6 deficiency affects pancreatic patterning and uncover an expected role of RFX6 in early pancreas morphology. The tunable differentiation system and stem cell-derived islet models described in this work may facilitate addressing fundamental questions in islet biology and probing human pancreas diseases.
