Long-term in vitro expansion of epithelial organoids from human colon, adenoma, adenocarcinoma and Barrett's Esophagus

ABSTRACT: Background & Aims: We have recently established long-term culture conditions under which single crypts or stem cells derived from murine small intestine expand over long periods of time. Growing crypts undergo multiple crypt fission events, whilst simultaneously generating villus-like epithelial domains in which all differentiated cell types are present. We have now adapted the culture conditions to grow similar epithelial organoids from mouse colon and human small intestine and colon. Methods: Based on the murine small intestinal culture system, we optimized the murine and human colon culture system. Results: Addition of Wnt3A to the growth factor cocktail allowed mouse colon crypts to expand indefinitely. Further addition of nicotinamide, a small molecule Alk inhibitor and a p38 inhibitor was essential for long-term human small intestine and colon culture. The culture system also allowed growth of murine Apcmin adenomas, human colorectal cancer and human esophageal metaplastic Barrett’s epithelium. Conclusion: The culture technology should be widely applicable as a research tool for infectious, inflammatory and neoplastic pathologies of the human gastrointestinal tract. Moreover, regenerative applications may become feasible with ex vivo expanded intestinal epithelia.

Moreover, regenerative applications may become feasible with ex vivo expanded intestinal epithelia. Human organoids were grown embedded in Matrigel in HISC (Human intestinal stem cell culture) medium. Additionally, human small intestinal crypts and villi were isolated independently from a freshly operated sample. RNA was isolated using the RNeasy Micro kit (Qiagen). Samples were labled according to Agilent guidelines with Cy3, whereas human reference RNA (Stratagene) was labeled in Cy5. Feature Extraction Software was used to extract and normalize data.

Small and large intestine differ in basal ERK pathway activity

Project description:In this experiment, we determined the differences in the transcriptomes of freshly isolated murine small intestine and colon derived crypts. The data shows that the mRNA profiles of the two tissues significantly differ in their ground state. Interestingly, we found that the expression levels of ERK pathway components as well as their positive and negative regulators significantly differ between small intestinal and colonic crypts. This observation indicates that the ERK pathway displays higher basal activity in the small intestine compared to the colon.

Enhancing single-cell cellular state inference by incorporating molecular network features

Project description:Although small intestine epithelium has been studied widely in murine, a comprehensive expression landscape in human is still lacking. To explore the cellular diversity of human small intestine epithelium, we sampled the ileal crypts from two patients suffered from right-sided colon cancer while their ilea were relatively normal. scRNA-seq libraries were generated using the 10X v3 Kit, which could guarantee both throughput and quality

In vitro expansion of human gastric epithelial stem cells and their primary response to bacterial infection

Project description:We previously established long-term 3D organoid culture systems for several murine tissues (intestine, stomach, pancreas and liver) as well as human intestine and pancreas. Here, we describe culture conditions to generate long-term 3D culture from human gastric stem cells. The technology can be applied to study the epithelial response to infection with Helicobacter pylori. Human gastric cultures can expand indefinitely in 3D Matrigel. Cultures can be generated from normal tissue, from single sorted stem cells, or from tumor tissue. Organoids maintain many characteristics of the respective tissue in terms of histology, marker expression and euploidy. Organoids from normal tissue express markers of four lineages of the stomach and self-organize in gland and pit-domains. They can be directed to specifically express either lineages of the gastric gland, or the gastric pit by addition of Nicotinamide and withdrawal of Wnt. While gastric pit lineages react marginally to bacterial infection, gastric gland lineages mount a strong inflammatory response. The gastric culture system provides a unique tool to study gastric pathologies.

Adult stem cells in the small intestine are intrinsically programmed with their location-specific function

Project description:Differentiation and specialisation of epithelial cells in the small intestine is regulated in two ways. First, there is differentiation along the crypt-villus axis of the intestinal stem cells into absorptive enterocytes, Paneth, goblet, tuft, enteroendocrine or M-cells, which is mainly regulated by WNT. Second, there is specialization along the cephalocaudal axis with different absorptive and digestive functions in duodenum, jejunum and ileum that is controlled by several transcription factors such as GATA4. However, so far it is unknown whether location-specific functional properties are intrinsically programmed within stem cells or if continuous signalling from mesenchymal cells is necessary to maintain the location-specific identity of the small intestine. By using the pure epithelial organoid technique, we show that region-specific gene expression profiles are conserved throughout long-term cultures of both mouse and human intestinal stem cells and correlated with differential Gata4 expression. Furthermore, the human organoid culture system demonstrates that Gata4-regulated gene expression is only allowed in absence of WNT signalling. These data show that location-specific function is intrinsically programmed in the adult stem cells of the small intestine and that their differentiation fate is independent of location-specific extracellular signals. In light of the potential future clinical application of small intestine-derived organoids, our data imply that it is important to generate GATA4-positive and GATA4-negative cultures to regenerate all essential functions of the small intestine.

DNA methylation analysis validates organoids as a viable model for studying human intestinal aging (methylation)

Project description:The epithelia of the intestine and colon turn over rapidly and are maintained by adult stem cells at the base of crypts. While the small intestine and colon have distinct, well-characterized physiological functions, it remains unclear if there are fundamental regional differences in stem cell behavior or region-dependent degenerative changes during aging. Mesenchyme-free organoids provide useful tools for investigating intestinal stem cell biology in vitro and have started to be utilized for investigating age-related changes in stem cell function. However, it is unknown whether organoids maintain hallmarks of age in the absence of an aging niche. Here we test whether stem cell enriched organoids preserve the DNA methylation-based aging profiles associated with the tissues and crypts from which they were derived. To address this, we use standard human methylation arrays and the human 'epigenetic clock' as a biomarker of age to analyze in vitro derived three-dimensional stem cell-enriched intestinal organoids. We find that human stem cell-enriched spheroids maintain segmental differences in methylation patterns and that age, as measured by the epigenetic clock, is largely maintained in spheroids. Surprisingly, we find that small intestine spheroids exhibit striking epigenetic age reduction relative to colon spheroids.

Reg4+ Deep Crypt Secretory cells function as epithelial niche for Lgr5+ stem cells in colon

Project description:Lgr5+ stem cells reside at crypt bottoms of the small and large intestine. Small intestinal Paneth cells supply Wnt3, EGF and Notch signals to neighboring Lgr5+ stem cells. While the colon lacks Paneth cells, Deep Crypt Secretory (DCS) cells are intermingled with Lgr5+ stem cells at crypt bottoms. Here, we report Reg4 as a marker of DCS cells. To investigate a niche function, we eliminated DCS cells using the diphtheria-toxin receptor gene knocked into the murine Reg4 locus. Ablation of DCS cells results in loss of stem cells from colonic crypts and disrupts gut homeostasis and colon mini-gut formation. In agreement, sorted Reg4+ DCS cells promote organoid formation of single Lgr5+ colon stem cells. Stem cells are forced to generate DCS cells in vitro by combined Notch inhibition and Wnt activation. We conclude that Reg4+ DCS cells serve as Paneth cell equivalents in the colon crypt niche.
