Construction of multilayered small intestine-like tissue by reproducing interstitial flow

ABSTRACT: Recent advances have made modeling human small intestines in vitro possible, but it remains a challenge to recapitulate fully their structural and functional characteristics. We suspected interstitial flow within the intestine, powered by circulating blood plasma during embryonic organogenesis, to be a vital factor. We aimed to construct an in vivo-like multilayered small intestinal tissue by incorporating interstitial flow into the system and, in turn, developed the micro-small intestine systems by differentiating definitive endoderm and mesoderm cells from human pluripotent stem cells simultaneously on a microfluidic device capable of replicating interstitial flow. This approach enhanced cell maturation and led to the development of a three-dimensional small intestine-like tissue with villi-like epithelium and an aligned mesenchymal layer. Our micro-small intestine system not only overcomes the limitations of conventional intestine models but also offers a unique opportunity to gain insights into the detailed mechanisms underlying intestinal tissue development.

Construction of small intestine-like tissue by reproducing interstitial flow on-chip

Project description:Significant progress has been recently achieved in generating in vitro human small intestine models. Nonetheless, there remains ample opportunity for enhancement, both in terms of structure and function, within the current model. In this study, our objective is to construct a multilayered small intestinal tissue composed of an intestinal epithelium, supportive mesenchymal cells, and an extracellular matrix. We developed a multilayered small intestinal tissue by differentiating human induced pluripotent stem cells on a microfluidic device capable of replicating interstitial flow. Under the interstitial flow exposure, a three-dimensional villus-like epithelium and mature intestinal epithelial cells, including polarized enterocytes or goblet cells, were observed in the small intestine tissue-on-a-chips. Further analysis revealed that intestinal fibroblasts and collagen fiber are localized to the basolateral side of the intestinal epithelium. Moreover, we confirmed that small intestine tissue-on-a-chips are useful for pharmaceutical and infectious disease research. Our small intestine tissue-on-a-chips not only overcome the limitations of conventional small intestine models but also offer a unique opportunity to understand the mechanisms underlying intestinal tissue development.

Multilayered Omics Revealsl Sex- and Depot-Dependent Adipose Progenitor Cell Heterogeneity

Project description:White adipose tissue (WAT) harbors functionally diverse subpopulations of adipose progenitor cells that differentially impact tissue plasticity in a sex- and depot-dependent manner. To date, the molecular basis of this cellular heterogeneity has not been fully defined. Here, we describe a multilayered omics approach to dissect adipose progenitor cell heterogeneity from in three dimensions: progenitor subpopulation, sex, and anatomical localization. We applied state-of-the-art mass spectrometry methods to quantify 4870 proteins in eight different stromal cell populations from perigonadal and inguinal WAT of male and female mice and acquired transcript expression levels of 15477 genes using RNA-seq. Notably, our data highlight the molecular signatures defining sex differences in PDGFR+ preadipocyte differentiation and identify regulatory pathways that functionally distinguish adipose tissue PDGFRb+ subpopulations. The data are freely accessible as a resource at "Pread Profiler. Together, the multilayered omics analysis provides unprecedented insights into adipose stromal cell heterogeneity.

Gene expression of donor monocytes recovered from various tissues of recipient mice one day after transfer

Project description:Monocyte are recruited to almost all peripheral tissues. Micro-environmental stimuli appeared to alter monocyte transcription once they enter the intestine and their subsequent development in the tissue. We therefore investigated whether there is tissue specific monocyte adaption and differentiation in vivo by examining donor monocytes in various tissues i.e. small intestine, liver, spleen and BM.

The aryl hydrocarbon receptor partially controls tissue adaptaion of intestinal eosinophils in mice

Project description:To determine how AHR affects eosinophil adaptation to the intestinal environment, eosinophils were sorted from the small intestine from WT, Ahr knockout and Ahrr knockout mice and compared by RNA sequencing. The canonical AHR pathway was active in murine intestinal eosinophils and limited eosinophil survival in the small intestine in a cell-intrinsic manner. Eosinophils from AHR-deficient mice retained increased expression of pathways associated with bone marrow eosinophils and failed to fully express the intestinal gene expression program, including extracellular matrix organization and cell junction pathways. Thus, our study demonstrates that the response to environmental triggers via AHR shapes tissue adaptation of eosinophils in the small intestine.

R-spondin 1 and noggin facilitate expansion of resident stem cells from non-damaged gallbladders.

Project description:Pioneering studies within the last few years have allowed the in vitro expansion of tissue-specific adult stem cells from a variety of endoderm-derived organs, including the stomach, small intestine and colon. Here we derived organoids from mouse gallbladder tissue (gallbladder organoids), from mouse liver (including the extrahepatic biliary ducts and gallbladder; liver organoids) and from mouse small intestine tissue (intestinal organoids). RNA was prepared from these organoids and used to assay expression of 21,258 genes using Affymetrix gene expression arrays. RNA was also prepared from mouse gallbladder, liver and small intestine tissues and used to assay gene expression in these tissues. Finally, gallbladder organoids were induced to differentiate by removing R-spondin 1 and noggin from the culture media and subjected to gene expression array analysis. RNA was extracted from mouse gallbladder organoids, differentiated gallbladder organoids, liver organoids, small intestine organoids, gallbladder tissue, liver tissue and small intestine tissue and then used for hybridization of Affymetrix gene expression microarrays.

Smarcad1 coordinates innate immunity-linked gene expression in the intestinal epithelium [Cocr RNA-seq]

Project description:Smarcad1 is one of the most conserved chromatin remodelling factors, from yeast to human, with suggested functions in gene silencing, heterochromatin maintenance and genome stability. However, its role in tissue function is poorly understood. As this factor is highly expressed in the stem- and proliferative zone in the intestinal epithelium, we explored the role of this factor in this tissue. Intestine tissue-specific deletion of Smarcad1 resulted in notable changes in gene expression in the small intestine, colon and organoids from small intestine.
