Transcriptional profiles of neural crest-derived progenitor cells from the small bowel and subcutaneous adipose tissue

ABSTRACT: Neural stem cells (NSCs) are most commonly sourced from neural tissue such as the central nervous system or the enteric nervous system (ENS) of the gut. Emerging evidence has shown that adipose tissue contains its own complex nervous system consisting of sympathetic and sensory innervation. The entirety of the peripheral nervous system is the progeny of Wnt1-expressing cells of the embryonic neural crest. This includes the ENS, autonomic neurons, and Schwann cell precursors that provide peripheral glial cells. Counterintuitive to their name, however, embryonic Schwann cell precursors represent multipotent stem cells that migrate along embryonic nerve fibers and contribute to glial and non-glial cell populations, including melanocytes, neuroendocrine chromaffin cells, enteric neurons, sympathetic neurons and mesenchymal stem cells from the bone marrow, depending on local environmental cues. However, no equivalent progenitors are known to exist postnatally in the nerve fiber niche. Schwann cells have been demonstrated to give rise to enteric neurons postnatally, suggesting they retain neuronal progenitor properties and offer a potential source of NSCs for regenerative therapies. In this study, we compare the transcriptomic properties of neural crest-derived NSCs from the intestine (enteric neural progenitors) and the nerve fibers of the subcutaneous adipose tissue and evaluate the effects of different methods of NSC culture and isolation.

Enteric glia express proteolipid protein 1 and are a transcriptionally unique population of glia in the mammalian nervous system

Project description:To identify the gene expression profile of enteric glia and assess the transcriptional similarity between enteric and extraenteric glia, we performed RNA sequencing analysis on PLP1-expressing cells in the mouse intestine. This analysis shows that enteric glia are transcriptionally unique and distinct from other cell types in the nervous system. Enteric glia express many genes characteristic of the myelinating glia, Schwann cells and oli- godendrocytes, although there is no evidence of myelination in the murine ENS. Total RNA expression profiles of PLP1 expressing enteric glial cells (GFP+) and non-glial cells (GFP-negative) were obtained from the ileum and colon of juvenile PLP1-eGFP transgenic mice.

RNA Expression Data from developing enteric nervous system (ENS) and bowel

Project description:The enteric nervous system (ENS) can control most essential gut functions owing to its organization into complete neural circuits consisting of a multitude of different neuronal subtypes. We used microarrays to identify transcription factor networks and signaling pathways involved in diversification and differentiation of enteric neurons during development of the enteric nervous system.

Loss of enteric neuronal Ndrg4 promotes colorectal cancer via increased release of Nid1 and Fbln2

Project description:The N-Myc Downstream-Regulated Gene 4 (NDRG4), a prominent biomarker for colorectal cancer (CRC), is specifically expressed by enteric neurons. Considering that nerves are important members of the tumor microenvironment, we here establish different Ndrg4 knockout (Ndrg4-/-) CRC models and an in-direct co-culture of primary enteric nervous system (ENS) cells and intestinal organoids to identify whether the ENS, via NDRG4, affects intestinal tumorigenesis. Linking immunostainings and gastrointestinal motility (GI) assays, we show that absence of Ndrg4 does not trigger any functional or morphological GI-abnormalities. However, combining in vivo, in vitro and quantitative proteomics data, we uncover that Ndrg4 knockdown is associated with enlarged intestinal adenoma development and that organoid growth is boosted by the Ndrg4-/- ENS cell secretome, which is enriched for Nidogen-1 (Nid1) and Fibulin-2 (Fbln2). Moreover, NID1 and FBLN2 are expressed in enteric neurons, enhance tumorigenic capacities of CRC cells and are enriched in human CRC secretomes. Hence, we provide evidence that the ENS, via loss of Ndrg4, is involved in colorectal pathogenesis and that ENS-derived Nidogen-1 and Fibulin-2 enhance colorectal carcinogenesis.

Single-cell profiling coupled with lineage analysis reveals vagal and sacral neural crest contributions to the developing enteric nervous system

Project description:During development, much of the enteric nervous system (ENS) arises from the vagal neural crest that emerges from the caudal hindbrain and colonizes the entire gastrointestinal tract. However, a second contribution to the ENS comes from the sacral neural crest that arises in the caudal neural tube and populates the post-umbilical gut. By coupling single cell transcriptomics with axial-level specific lineage tracing in avian embryos, we compared the contributions of embryonic vagal and sacral neural crest cells to the pre-umbilical and post-umbilical chick ENS and the associated peripheral ganglia (the Nerve of Remak and pelvic plexuses) at embryonic day (E) 10.

Engineered human pluripotent stem cell-derived intestinal tissues with a functional enteric nervous system

Project description:The enteric nervous system (ENS) of the gastrointestinal (GI) tract controls many diverse functions including motility and epithelial permeability. Perturbations in ENS development or function are common, yet a human model to study ENS-intestinal biology is lacking. We have used a tissue engineering approach with pluripotent stem cells (PSCs) to generate human intestinal tissue containing a functional ENS. We recapitulated normal intestinal ENS development by combining PSC-derived neural crest cells (NCCs) with developing human intestinal organoids (HIOs). When cultured alone, NCCs had full differentiation potential in vitro, however when recombined with HIOs they differentiated into neurons and glial cells. NCC-derived ENS neurons self-assembled within the developing intestinal mesenchyme and exhibited neuronal activity as measured by rhythmic waves of calcium transients. ENS-containing HIOs grown in vivo formed neuroglial structures similar to a myenteric and submucosal plexus, formed interstitial cells of Cajal, and had an electro-mechanical coupling that regulated waves of propagating contraction. This is the first demonstration of a human PSC-derived intestinal tissue with a functional ENS.

Expression data from embryonic day 17 (E17) enteric neural crest-dervied cells (ENCDC) and non-ENCDC

Project description:During the later stages of enteric nervous system (ENS) development, enteric neural crest derived cells (ENCDC) that have colonized the bowel must complete differentiating and mature into neurons and glia. This process is controlled by a complex array of intrinsic and extrinsic factors. We used microarrays to dermine which genes were differntially expressed in ENCDC versus other cells in the developing bowel. We identified many geness enriched in ENCDC with potential roles in the later stages of ENS development

Maturing an Enteric Nervous System in Human Intestinal Organoid-derived Tissue-Engineered Small Intestine

Project description:Acquired or congenital disruption in enteric nervous system (ENS) development or function can lead to significant mechanical dysmotility. ENS restoration through cellular transplantation may provide a cure for enteric neuropathies. We have previously generated human pluripotent stem cell (hPSC)-derived tissue-engineered small intestine (TESI) from human intestinal organoids (HIO). However, HIO-TESI fails to develop an ENS. In a previous report of combined HIO with additional human enteric neural crest cells (ENCC), an ENS was established but lacked maturity. The purpose of our study is to establish a mature ENS derived exclusively from hPSC in HIO-TESI. hPSC-derived ENCC supplementation of HIO-TESI generates ENCC-HIO-TESI with mature submucosal and myenteric ganglia, repopulates excitatory, inhibitory, and sensory neurons, and restores the neuroepithelial circuit and neuron-dependent contractility and relaxation. Our findings validate a novel approach to restoring a functional hPSC-derived ENS in ENCC-HIO-TESI and implicate their potential for the treatment of enteric neuropathies.

Analysis of gene expression in Sox10 Dom mutant sacral neural crest cells

Project description:Hirschsprung’s disease (HSCR) is a congenital disease which is characterized by the reduction or absence of neurons and glial cells in the enteric nervous system (ENS). Failure of neural crest cells (NCCs) to colonize the gut during the embryonic development has been considered as one of the possible causes of the disease. In this study, the migration and gene expression of sacral NCCs from the spontaneous mouse mutant Dominant megacolon (Dom) which is a HSCR animal model expressing a mutated transcription factor Sox10, were analyzed in order to identify candidate genes which may possibly affect the NCC migration in the mutant.

Early shaping of the chromatin landscape specifies vagal neural crest into distinct lineages [RNA-seq]

Project description:Complex traits in enteropathies like Hirschsprung disease underscores a larger gene regulatory network (GRN) driving vagal neural crest (VNC) to form the enteric nervous system (ENS). To dissect the GRN and understand the function of non-coding regulatory regions, we used a novel highly conserved EdnrB E2 enhancer with a FoxD3 NC2 enhancer to generate a comprehensive map of VNC chromatin and transcriptional landscape during ENS development. Together with single-cell transcriptional profiles, we revealed three distinct lineages of VNC (glial, neuronal, and mesenchymal) that are each pre-specified by independent GRNs before delamination. We identified and functionally validated regulatory cores mediating the glial (Tfap2B and Sox10) and neuronal programmes (Sox3/Msx1) that in spatiotemporal combinations with other families of transcription factors, control the timing of enteric cell differentiation. Deconstructing the VNC-GRN identifies factors that pre-specifies cells to their presumptive fate and sheds light on how early GRN dysregulations influence the divergent neural phenotype in enteropathies.
