(Submitter supplied) Enteroendocrine cells (EECs) constitute only a small proportion of Villin-1 (Vil1)-expressing intestinal epithelial cells (IECs) of the gastrointestinal tract; yet, in sum, they build the largest endocrine organ of the body, with each of them storing and releasing a distinct set of peptides for the control of feeding behavior, glucose metabolism, and gastrointestinal motility. Like all IEC types, EECs are continuously renewed from intestinal stem cells in the crypt base and terminally differentiate into mature subtypes while moving up the crypt-villus axis. more...

(Submitter supplied) Enteroendocrine cells (EECs) alter hormone expression while migrating along the crypt-villus axis. We report this swich is regulated by a BMP morphogen gradient. Single cell RNA sequencing of control and BMP4 stimulated EECs was performed using organoids from different hormone reporter mice. We show that BMP4 stimulation can switch different subsets of EECs from their crypt to villus state.

(Submitter supplied) In this study, similarities between EECs and β-cells were evaluated in detail. To obtain specific subtypes of EECs, cell sorting by flow cytometry was conducted from STC-1 cells (a heterogenous EEC line), and each single cell was cultured and passaged. Five EEC subtypes were established according to hormone expression, measured by quantitative RT-PCR and immunostaining: L, K, I, G and S cells expressing glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide, cholecystokinin, gastrin and secretin, respectively. more...

(Submitter supplied) Enteroendocrine cells are hormonal secreting cells in the gut. However, as they comprise <1% of the total epithelial cell population, studies on their response to stimuli have been limited. Chang-Graham, Danhof, Engevik, and Tomaro-Duchesneau et al (PMID 31029854) developed a model enteroid system to overcome this limitation. By driving expression of NGN3 in human jejunal enteroids, their system allows for analysis of hormonal secretion and transcriptional analysis in response to a stimulus. more...

(Submitter supplied) Analysis of FACS-sorted intestinal Neurog3+/+ and Neurog3+/- cells from Neurog3 fluorencent reporter mice carrying two-(+/+) or one- (+/-) Neurog3 alleles. In the intestine, Neurog3 is an enteroendocrine (EE) lineage determinating transcription factor that transiently expressed in early EEC progenitors. By comparison the molecular profiles of Neurog3+/+ and Neurog3+/- cells, we hypothesized that Neurog3 gene dosage regulates the allocation of EE progenitor fates towards EEC vs. more...

(Submitter supplied) Objective: Enteroendocrine cells (EECs) survey the gut luminal environment and co-ordinate hormonal, immune and neuronal responses to it. They exhibit well characterized physiological roles ranging from the control of local gut function to whole body metabolism, but little is known regarding the regulatory networks controlling their differentiation, especially in human gut. The small molecule Isoxazole-9 (ISX-9) has been shown to stimulate neuronal and pancreatic beta-cell differentiation, both closely related to EEC differentiation. more...

(Submitter supplied) Background and aims: Enteroendocrine cells (EECs) and their hormones are essential regulators of whole-body energy homeostasis. EECs sense luminal nutrients and microbial metabolites and subsequently secrete a variety of hormones acting locally or at distance. Impaired development of EECs during embryogenesis is life-threatening in newborn mice and humans due to compromised nutrient absorption. However, the physiological importance of the EEC system in adult mice has not been directedly studied. more...

(Submitter supplied) To identify the genes differentially expressed in jejunal enteroendocrine cells (EECs) under a high fat diet we purified EEC (eYFP+) and non-EEC(eYFP-) using FACS from jejunal villi of Neurog3eYFP/+ mice (Mellitzer et al, Mol. Endo 2004) fed with a normal chow or high fat diet (HFD). In Neurog3eYFP/+ mice enteroendocrine progenitors and their descendants are labeled with eYFP. We then purified the RNA and perfomed gene exspression profiling using RNAseq.

(Submitter supplied) Background: Endocrine cells of the digestive system, including the pancreatic endocrine cells (PECs) clustered in the islets of Langerhans and the enteroendocrine cells (EECs) scattered in the intestinal epithelium, play an important role in metabolism. Although EECs and PECs are located in distinct organs, they share many features and several common genes control their differentiation. In this study, we investigated comprehensively the similarity of EECs and PECs by defining their transcriptomic landscape and comparing the regulatory networks controlled by pax6b, a key player in both EECs and PECs. more...

(Submitter supplied) Aim: The mammalian gut is the largest endocrine organ. Dozens of hormones secreted by enteroendocrine cells regulate a variety of physiological functions of the gut but also of the pancreas and brain. Here, we examined the role of the helix-loop-helix transcription factor ID2 during the differentiation of intestinal stem cells along the enteroendocrine lineage. Methods: To assess the functions of ID2 in the adult mouse small intestine, we used single-cell RNA sequencing, genetically modified mice, and organoid assays. more...

(Submitter supplied) Enteroendocrine L-cells release hormones that control metabolism and appetite and are targets under investigation for the treatment of diabetes and obesity. Understanding L-cell diversity and expression profiles is critical for identifying target receptors that will translate into altered hormone secretion. We performed single cell RNA sequencing of mouse L-cells from the upper small intestine to distinguish cellular populations, revealing that L-cells form 3 major clusters: a group with typical characteristics of classical L-cells, including high expression of Gcg and Pyy; a cell type overlapping with Gip-expressing K-cells; and a unique cluster expressing Tph1 and Pzp that was predominantly located in duodenal villi and co-produced 5HT. more...

(Submitter supplied) Lgr5+ adult intestinal stem cells are highly proliferative throughout life. Single Lgr5+ stem cells can be cultured into 3D epithelial organoids containing all cell types at nearnormal ratios. Culture conditions to generate the main cell types have been established previously, but signals inducing the various types of enteroendocrine cells (EECs) have remained elusive. Here we generate quiescent Lgr5+ stem cells in vitro by inhibition of the EGF-receptor (EGFR) and mitogen-associated protein kinase (MAPK) signaling pathways in organoids, a state that can be readily reversed. more...

(Submitter supplied) Enteroendocrine cells (EECs) secrete serotonin (enterochromaffin [EC] cells) or specific peptide hormones (non-EC cells) that serve vital metabolic functions. The basis for terminal EEC diversity remains obscure. By forcing activity of the transcription factor (TF) NEUROG3 in 2D cultures of human intestinal stem cells, we replicated physiologic EEC differentiation and examined transcriptional and cis-regulatory dynamics that culminate in discrete cell types. more...
