RNA-seq of transplanted pluripotent stem cells-derived human intestinal organoids upon mechanical lengthening and human jejunum tissues

ABSTRACT: Human Intestinal Organoids (HIOs) generated from embryonic and/or induced pluripotent stem cell lines offer an avenue to study both developmental and human specific disease states. Recently, progress has been made in scaling and maturing these inherently immature tissues through transplanting them in vivo. However, these resultant grafts best approximate fetal intestinal tissue thus limiting their utility. To induce growth and maturation of HIOs we used a nitinol spring device to mechanically induce enterogenesis of HIO in vivo. HIOs are cultured prior to implantation within the mesentery of immunodeficient mice. They are allowed to grow, vascularize, and mature before a second procedure is performed wherein a compressed nitinol spring is implanted within the lumen of the transplanted HIO (tHIO). Next Generation RNA sequencing was performed across transplanted samples as well as on human surgical samples to highlight the transcriptional similarities and differences between groups. Transcriptionally, the tHIO+S samples were more similar to human tissues than the tHIO. With these initial experiments, we concluded that the application of an intraluminal uniaxial force is a practical method to induce maturation of tHIOs in vivo without concomitant architectural disruptions. While our current system does lack certain complexities, we have demonstrated enterogenesis by means of mechanical manipulation.

Epithelial maturation of human intestinal organoids from pluripotency entirely in vitro

Project description:In vitro human pluripotent stem cell derived intestinal organoids (HIOs) are immature and lack for diverse differentiated secretory cell types. We would like to test the hypothesis whether addition of a mesenchyme secreting ligand which is depleted in canonical organoid culture media could increase the maturity and secretory cell type diversity in HIOs in vitro. To do this, we adapted the directed differentiation protocol of HIOs by growing HIOs in media with EGF, NOGGIN, R-spondin-1 (ENR) for 30 days, isolated epithelial cells with dispase, recovered them with adult intestinal enteroid media with Wnt-3A (WENR). Then we introduced the mesenchyme secreting ligand NRG1 to the established enteroid culture (WENR+NRG1) and compared them to the enteroids grown in control condition (WENR).

Project description:Here, we used single-cell RNA-sequencing (scRNA-seq) to profile pluripotent stem cell-derived human intestinal organoids (HIOs) grown in media comprised of minigut media + varying concentrations of Epiregulin (EREG) 1 ng/ml, 10 ng/ml, 100 ng/ml after 28 days of in vitro growth.

RNA-seq of human intestinal organoids colonized with E. coli and other immature intestinal tissues

Project description:We performed RNA-seq to demonstrate that the epithelium of human pluripotent stem cell-derived human intestinal organoids is globally similar to the immature human epithelium and we utilize HIOs to investigate complex host-microbe interactions in this naive epithelium. RNA was isolated using the mirVana RNA isolation kit and following the \Total RNA\ isolation protocol (Thermo-Fisher Scientific, Waltham MA). RNA library preparation and RNA-sequencing (single-end, 50 bp read length) were performed by the University of Michigan DNA Sequencing Core using the Illumina Hi-Seq 2500 platform. Transcriptional quantitation analysis was conducted using 64-bit Debian Linux stable version 7.10 (\Wheezy\). Pseudoalignment of RNA-seq data was computed using kallisto v0.43.0 and differential expression of pseudoaligned sequences was calculated using the R package DEseq2.

RNA-seq of human intestinal organoids infected with Salmonella enterica at 2.5h and 8h post infection

Project description:The purpose of this experiment was to identify intestinal epithelial responses to various strains of Salmonella enterica. Human intestinal organoids were infected with three serovars of Salmonella; Typhimurium, Enteritidis and Typhi, as well as type 3 secretion system -1 and -2 mutants in Typhimurium in order to identify host responses that were similar and unique to each serovar, and responses that were dependent on these secretion systems.

scRNA-seq of hPSC-derived human intestinal organoids with endogenous vascular endothelial cells

Project description:The development of human pluripotent stem cell (hPSC)- derived small intestinal organoids (HIOs) has led to an improved understanding of human intestinal development and physiology. HIOs generated using directed differentiation lack some cellular populations found in the native organ, including vasculature. We performed single cell RNA sequencing (scRNA-seq) on approximately 13,000 cells at various timepoints (0, 3, 7, and 14 days) across HIO in vitro development and observed a transient population of endothelial-like cells (ECs) present within HIOs early during differentiation. Our data demonstrate that EC-like cells fail to be robustly maintained in long term culture. Here, we have developed a new directed differentiation approach to enhance co-differentiation and maintenance of ECs within HIOs, leading to the development of vascularized HIOs (vHIOs). scRNAseq was used to compare vHIOs to control HIOs after 59d months in culture.

Examination of the role of BMP signaling in patterning of human pluripotent stem cell derived mid/hindgut spheroids and maintenance of this patterning in organoids transplanted under mouse kidney capsules.

Project description:The goal of this study was to test the hypothesis that BMP signaling regulates patterning of human CDX2+ gut tube cultures (Spence et al 2011, Watson et al. 2014). The study is comprised of 2 separate experiments. The first experiment was to determine the immediate impact of BMP signaling on CDX2+ gut tube cultures. To do so we tested spheroids, spheroids after plating in Matrigel and exposed to 3 days of Noggin (100ng/mL), spheroids after plating in Matrigel and exposed to 3 days of EGF alone (100ng/mL, Control), and spheroids after plating in Matrigel and exposed to 3 days of BMP2 (100ng/mL). RNA was collected from spheroids and spheroids after 3 days of patterning. The second experiment examined if patterning was maintained after this initial 3 days of patterning and an addition 8-10 weeks following transplantation in vivo. To do this we grew all Matrigel plated spheroids for an additional 25 days in media containing EGF alone (Control media). We then transplanted these organoids under the mouse kidney capsule and allowed them to mature for 8-10 weeks. We then collected RNA from the transplanted organoids.
