A Human Pluripotent Stem Cell Surface N-Glycoprotein resource including New Markers, Extracellular Epitopes, and Drug Targets

ABSTRACT: Detailed knowledge of cell surface proteins for isolating well-defined populations of human pluripotent stem cells (hPSCs) would significantly enhance their characterization and translational potential. Normal H9 human embryonic stem cells and the KB3 human induced pluripotent stem cell lines were analyzed by Cell Surface Capture Technology, and in parallel transcript profiles from five independent samples (i.e., Replicas 1-5 for each) were performed to facilitate protein and transcriptomic comparisons.

Isolation of epiblast stem cells from pre-implantation mouse embryos

Project description:Pluripotent stem cells provide a platform to interrogate control elements that function to generate all cell types of the body. Despite their utility for modeling development and disease, the relationship of mouse and human pluripotent stem cell states to one another remains largely undefined. We have shown that mouse embryonic stem (ES) cells and epiblast stem cells (EpiSCs) are distinct, pluripotent states isolated from pre- and post-implantation embryos respectively. Human ES cells are different than mouse ES cells and share defining features with EpiSCs, yet are derived from pre-implantation human embryos. Here we show that EpiSCs can be routinely derived from pre-implantation mouse embryos. The pre-implantation-derived EpiSCs exhibit molecular features and functional properties consistent with bona fide EpiSCs. These results provide a simple method for isolating EpiSCs and offer direct insight into the intrinsic and extrinsic mechanisms that regulate the acquisition of distinct pluripotent states. 6 total samples were analyzed. Three pluripotent cell types (mES cells, E3.5 EpiSCs, and E5.5 EpiSCs) were compared with and without treatment of SB431542 for 4 days.

AQP5-Expressing Cells Serve as Stem Cells and Cancer Origins in the Distal Stomach

Project description:Isolating adult stem cells from human stomach epithelia has proven challenging due to a lack of surface markers that are amenable to antibody-based sorting approaches. Here, through comparative expression profiling of mouse Lgr5+ adult stem cells along the gastrointestinal tract, we identify novel pylorus-specific stem cell markers, including the membrane protein Aqp5. FACS-based isolation of endogenous AQP5+ cells from healthy human pyloric stomach revealed their stem cell identity in organoid assays. Using new Aqp5-driven CreERT2 mouse models to selectively target conditional mutations to the pyloric stem cell compartment in vivo, we establish pyloric stem cells as a major source of Wnt-driven invasive gastric cancer. The new stem cell markers and mouse models described here will be an invaluable resource for deciphering early gastric cancer formation and for isolating and characterizing human stomach stem cells as a prerequisite to potentially exploiting their regenerative medicine potential in the clinic.

AQP5-Expressing Cells Serve as Stem Cells and Cancer Origins in the Mouse and Human Pyloric Stomach

Project description:Isolating adult stem cells from human stomach epithelia has proven challenging due to a lack of surface markers that are amenable to antibody-based sorting approaches. Here, through comparative expression profiling of mouse Lgr5+ adult stem cells along the GI tract, we identify novel pylorus-specific stem cell markers, including the membrane protein Aqp5. FACS-based isolation of endogenous AQP5+ cells from healthy human pyloric stomach revealed their stem cell identity in organoid assays. Using new Aqp5-driven CreERT2 mouse models to selectively target conditional mutations to the pyloric stem cell compartment in vivo, we establish pyloric stem cells as a major source of Wnt-driven invasive gastric cancer.

Cell-surface proteomics identifies differences in signalling and adhesion protein expression between naive and primed human pluripotent stem cells

Project description:Naive and primed human pluripotent stem cells (hPSC) provide valuable models to study cellular and molecular developmental processes. The lack of detailed information about cell-surface protein expression in these two pluripotent cell types prevents an understanding of how the cells communicate and interact with their microenvironments. Here, we used plasma membrane profiling to directly measure cell-surface protein expression in naive and primed hPSC. This unbiased approach quantified over 1700 plasma membrane proteins including those involved in cell adhesion, signalling and cell interactions. Notably, multiple cytokine receptors upstream of JAK-STAT signalling were more abundant in naive hPSC. In addition, functional experiments showed that FOLR1 and SUSD2 proteins are highly expressed at the cell surface in naive hPSC but are not required to establish human naive pluripotency. This study provides a comprehensive stem cell proteomic resource that uncovers differences in signalling pathway activity and has identified new markers to define human pluripotent states.

Metabolites of human neurons and stem cells (siNeuron metabolomics)

Project description:There are a total of four samples each for this analysis. Each sample consists of the cells grown on three 10 cm culture plates. Each plate should have 2x106 cells for a total of 6x106 cells per sample when all three plates are combined. The first sample is undifferentiated human embryonic stem cells, the second sample is human glutamatergic neurons derived from those human embryonic stem cells, the third sample is undifferentiated human induced pluripotent stem cells and the fourth sample is human glutamatergic neurons derived from those human induced pluripotent stem cells.
