Single cell transcriptome profiling of mouse and hESC-derived pancreatic progenitors

ABSTRACT: Human embryonic stem cells (hESCs) are a potential unlimited source of insulin-producing β-cells for diabetes treatment. A greater understanding of how β-cells form during embryonic development will improve current hESC differentiation protocols. As β-cells are formed from NEUROG3-expressing endocrine progenitors, this study focused on characterizing the single-cell transcriptomes of mouse and hESC-derived endocrine progenitors. To do this, 7,223 E15.5 and 6,852 E18.5 single cells were isolated from Neurog3-Cre; Rosa26mT/mG embryos, allowing for enrichment of endocrine progenitors (yellow; tdTomato + EGFP) and endocrine cells (green; EGFP). From a NEUROG3-2A-eGFP CyT49 hESC reporter line (N5-5), 4,497 hESC-derived endocrine progenitor cells were sequenced. Differential expression analysis reveals enrichment of markers that are consistent with progenitor, endocrine, or novel cell-state populations. This study characterizes the single-cell transcriptomes of mouse and hESC-derived endocrine progenitors and serves as a resource (https://lynnlab.shinyapps.io/embryonic_pancreas/) for improving the formation of functional β-like cells from hESCs.

RNA-seq of Human Embryonic Stem Cell derived pancreas progenitor differentiation, Day 13 of wildtype, HES1-/-, NEUROG3-/- and HES1-/-NEUROG3-/- genotypes

Project description:To better understand the mechanism by which HES1 regulates pancreas development we took advantage of recent developments in directed differentiation of human embryonic stem cells (hESCs) to the pancreatic endocrine lineage via a series of progenitor stages (Figure 1 and (Rezania et al., 2014). Using the iCRISPR platform (González et al., 2014), we introduced indels in the HES1 and NEUROG3 genes, either singly or in combination in iCRISPR H1 cells. Using previously described gRNAs (Zhu et al., 2016) to target exon2 of the NEUROG3 gene and exon2 of the HES1 gene we detected by Sanger and RNA-sequencing a 2 bp insertion and a T insertion, respectively, resulting in premature STOP codons in two/multiple clonal cell lines carrying the introduced mutation and the loss of NEUROG3 by immunostaining We then subjected two or more clonal lines of H1-iCRISPR (wildtype), HES1−/−, NEUROG3−/− and HES1−/−NEUROG3−/− (abbreviated H1N3-dKO or H1−/−N3−/−) to differentiation to β-like cells using a modified version of the protocol from Rezania et al. (2014). Marker analysis showed that all cell lines maintained pluripotency (OCT4+) as hESC and were able to differentiate to FOXA2+ and SOX17+ co-positive definitive endoderm (DE, Day 3), PDX1+ cells at the posterior foregut stage (PF, Day 7), to bipotent progenitors marked by PDX1+ and NKX6-1+ at the Pancreatic Endoderm stage (PE, Day 10), and the Endocrine Precursor stage (EP, Day 13)

Genome wide profiling of NEUROG3 occupancy in human pancreatic endocrine progenitors [CUT&RUN]

Project description:Despite this critical role in islet cell development, the precise function and downstream genetic programs regulated directedly by NEUROG3 remain elusive. We therefore mapped genome-wide NEUROG3 occupancy in human induced pluripotent stem cell (iPSC)-derived endocrine progenitors and determined NEUROG3 dependency of associated genes to uncover direct targets. To this aim, we generated a novel hiPSC line (NEUROG3-HA-P2A-Venus), where NEUROG3 is HA-tagged and fused to a self-cleaving fluorescent VENUS reporter. We used the CUT&RUN technique, an alternative method to CHIP-seq allowing transcription factor profiling from a low cell number, to map NEUROG3 occupancy and epigenetic marks in pancreatic endocrine progenitors (PEP) differentiated from this hiPSC line. To optimize the stringency and relevance of NEUROG3 binding sites, we focused our analysis on regions identified both with HA and NEUROG3 antibodies and integrated NEUROG3 occupancy data with chromatin status and gene expression in PEPs and their NEUROG3-dependence. Mapping of NEUROG3 genome occupancy in PEPs uncovers an unexpectedly broad, direct control of the endocrine gene regulatory network (GRN) and raises novel hypotheses on how this master regulator controls islet and beta cell differentiation.

Retinoic acid signaling within pancreatic endocrine progenitors regulates mouse and human pancreatic islet cell specification

Project description:Retinoic acid (RA) signaling is essential for multiple developmental processes, including appropriate pancreas formation from the foregut endoderm. RA is also required to generate pancreatic progenitors from human pluripotent stem cells. However, the role of RA during the later stages of pancreas development is not well understood. In this study, we generated an inducible system to block RA signaling and demonstrate that disruption of the RA pathway within the Neurog3-expressing endocrine progenitor population is required for appropriate mouse b cell differentiation and repression of critical d cell genes, including Somatostatin. In addition, inhibition of the RA pathway in hESC-derived pancreatic progenitors downstream of NEUROG3 induction impairs INSULIN expression. We further determined that RA-regulation of endocrine cell differentiation is mediated through Wnt pathway components. Together, these data demonstrate the importance of RA signaling in endocrine specification and identify conserved mechanisms by which RA signaling directs endocrine cell fate.

Open chromatin landscape of pancreatic endocrine progenitors

Project description:During embryonic development, islet progenitors are specified from pancreatic duct cells by transient expression of Neurog3, a transcription factor necessary and sufficient for initiation of islet development. To understand the dynamics of Neurog3-dependent endocrine cell fate determination, in this study we used ATAC-Seq to identify accessible genomic regions of purified duct, endocrine progenitor, and endocrine cells isolated from mice with varying Neurog3 dosage

Expression DATA from E11.5 pancreatic buds treated with I-BET151 or JQ1 for 24h

Project description:Bromodomain and Extra-terminal (BET) proteins are epigenetic readers that interact with acetylated lysines of histone tails. Recent studies have demonstrated their role in cancer progression, as they recruit key components of the transcriptional machinery to modulate gene expression. However, their role during embryonic development of the pancreas has never been studied. Using mouse embryonic pancreatic explants and human IPSC, we show that inhibition of BET proteins with either I-BET151 or JQ1 dramatically enhances the number of neurogenin3 (NEUROG3) endocrine progenitors, leading to an increased number of endocrine cells in the pancreatic explants. Despite inducing several β cell markers, BETi also strongly down-regulated Ins1 expression in developed explants and adult β cells. However, removal of BETi from explants prior to β cell development, as NEUROG3 expression peaks, further led to enhanced β cell development with higher expression of insulin and maturation markers UCN3 and MAFA. Altogether, these results show that BET proteins play a major role in the pancreas endocrine differentiation. Furthermore, they highlight the potential use of BETi to improve β cell replacement therapies.

Mesenchymal progenitors from hESCs & profiling vs. BMMSCs

Project description:New potential sources of stem cells for clinical application include bone marrow mesenchymal stem cells (BMMSCs), human embryonic stem cells (hESCs), and induced pluripotent stem cells (iPS). However, each source is not without its own concerns. While research continues in an effort overcome these problems, the generation of mesenchymal progenitors from existing hESC lines may circumvent many of these issues. We report here a comparison of the transcriptome of hESC-derived mesenchymal progenitors (EMPs), its parental hESC line, and 2 donors of adult BMMSCs. A custom-designed oligo-microarray of just over 11,000 highly-expressed genes in stem cells was used to profile the transcriptome of BMMSCs, EMPs, and hESCs.

Neurog3-independant role of Notch signaling in pancreas explants. Microarray of pancreata of Wildtype or Neurog3tTA/tTA (Neurog3-Null) background at E12.5, explanted for 3d + treatment 24h with DAPT/vehicle.

Project description:Since loss of Hes1 and Notch signalling drives progenitors to the endocrine lineage, we set up a pancreas explant system with crosses of heterozygous Neurog3tTA/+, a knock-in allele which makes the homozygote Neurog3tTA/tTA embryos deficient in Neurog3 (hereafter Neurog3-null). Hereby endocrine differentiation is impeded and we can study the Neurog3-independent role of Notch signalling by DAPT inhibition of γ-secretase. E12.5 wildtype and Neurog3-null pancreata were explanted on fibronectin, grown for 3 days, and then treated with vehicle control (0.1% DMSO) or DAPT for 24h. RNA was isolated and subjected to Agilent microarray analysis

Gene expression analysis of hESC-derived-MESP1 expressing progenitors

Project description:A hESC MESP1-MCHERRY reporter line was used to isolate and study the molecular character of MESP1 expressing pre-cardiac progenitors, derived from hESC. MESP1 is a key-transcription factor for pre-cardiac mesoderm and is marking the progenitor for almost all cells of the heart. This reporter line was used to study cardiac differentiation and the derivation of early cardiac progenitors in vitro. hESCs were differentiated towards the cardiac lineage, expressing MESP1-mCherry at day 3 of differentiation. Total RNA obtained from isolated MESP1-mCherry expressing progenitors was compared to that of non-MESP1-expressing progenitors and undifferentiated hESCs in order to characterize MESP1-specific transcription factors and proteins.
