Project description:Pluripotent stem cells can be generated by pure small molecule compounds. However, only fibroblasts, a heterogeneous cell population, were reported for use in chemical reprogramming, and the efficiency is relatively low, raising the possibility that chemically induced pluripotent stem cells (CiPSCs) are derived from a specific cell subpopulation residing in fibroblast culture. Thus, it is of interest to know whether chemical reprogramming can be induced in other cell types, even using the same chemical cocktail. Here, using lineage tracing, we verify the generation of CiPSCs from fibroblasts. We further demonstrate that neural stem cells (NSCs) and small intestinal epithelial cells (IECs), cell types from the ectoderm and endoderm, respectively, can be chemically reprogrammed into pluripotent stem cells. CiPSCs derived from NSCs and IECs resemble mouse embryonic stem cells (ESCs) in terms of proliferation rate, global gene expression profiling, epigenetic status, self-renewal and differentiation capacity, and germline transmission competency. Interestingly, in the chemical reprogramming process from different cell types, a pluripotency gene Sall4 was commonly expressed in the initial stage, and the same core small molecules were required, suggesting conservatism underlying chemical reprogramming from different cell types. Moreover, the use of these small molecules should be fine-tuned to meet the requirement of reprogramming from different cell types. Together, these findings demonstrate that our reported chemical reprogramming approach can be reproduced in different cell types and suggest that chemical reprogramming is a promising strategy with the potential to be extended to more initial cell types. We analyzed the gene expression profiles of NSC-derived CiPSCs and IEC-derived CiPSCs ,using RNA-Sequencing. NSCs, IECs, and embryonic stem cells (R1) are controls.

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.

Project description:The columnar epithelial cells comprising the intestinal tract, stomach, and uterus can be cultured in vitro as organoids or in adherent culture. However, the proliferation of these columnar epithelial cells in adherent culture is limited. Likewise, human pluripotent stem cell (hPSC)-derived intestinal epithelial cells do not show extensive or clonal propagation in vitro. In this study, we induced proliferation of hPSC-derived small intestinal epithelium for a longer time by utilizing mesenchymal stromal cells derived from self-organized intestinal organoids as feeders. The proliferating cells exhibited columnar form, microvilli and glycocalyx formation, and cell polarity, as well as expression of drug-metabolizing enzymes and transporters. It is noteworthy that small intestinal epithelial stem cells cannot be cultured in adherent culture alone, and the stromal cells cannot be replaced by other feeders. Organoid-derived mesenchymal stromal cells resemble the trophocytes essential for maintaining small intestinal epithelial stem cells and play a crucial role in adherent culture. The high proliferative expansion, productivity, and functionality of hPSC-derived small intestinal epithelial stem cells could have potential applications in pharmacokinetic and toxicity studies and regenerative medicine.

Project description:Human intestinal epithelial organoids (IEO) culture models are rapidly emerging as novel experimental tools to investigate fundamental aspects of intestinal epithelial (patho)physiology. Cellular source and culture protocols vary between different IEO models and reliable markers for their characterization/validation are currently limited. Here, we provide the following reference datasets of transcriptomic profiling by RNA-sequencing: Purified intestinal epithelial cells (EpCAM+) from paediatric ileum and colon, Intestinal organoid cultures from paediatric ileum and colon, Purified intestinal epithelial cells (EpCAM+) from foetal small intestine and foetal large intestine, Intestinal organoid cultures from foetal small intestine and foetal large intestine, Intestinal organoid cultures derived from induced pluripotent stem cells.<br> Complementary data from methylation profiling on the same samples have been deposited at ArrayExpress under accession number E-MTAB-4957 ( https://www.ebi.ac.uk/arrayexpress/experiments/E-MTAB-4957 ).</br>

Project description:We developed a compartmental model of the small intestinal epithelium that describes stem and progenitor cell proliferation and differentiation and cell migration onto the villus. The model includes a negative feedback loop from villus cells to regulate crypt proliferation and integrates heterogeneous epithelial-related processes, such as the transcriptional profile, citrulline kinetics and probability of diarrhea.

Project description:PD0325901 is involved in improving reprogramming efficiency during inducing pluripotent stem cells (iPSC) or maintain a blastocyst-like state in embryonic stem cells (ESC). However, the knowledge about this small molecule regulating miRNAs in ESC was limited. To understand the role of miRNAs during PD03-induced ESC maintenance and gain an insight how PD0325901 regulates miRNAs expression; we performed small RNA sequencing using Illumina HiSeq 2000 under the compounds treatment. The data show the miRNAs regulated by PD0325901.

Project description:Pluripotent stem cells can be induced from somatic cells, providing an unlimited cell resource for regenerative medicine. However, genetic manipulation and difficult-to-manufacture strategies used in reprogramming limit their clinical applications. Here, we show pluripotency can be induced from mouse somatic cells by specific small-molecule compounds. The completely chemically-induced pluripotent stem cells (CiPSCs) can be stably maintained in embryonic stem cell (ESC) culture medium and resemble ESCs in terms of their gene expression profiles, epigenetic status, and potential for differentiation and germline transmission. These findings suggest that exogenous master genes are dispensable for cell fate reprogramming and pave the way for the clinical application of somatic reprogramming techniques.
