Differential 5-FU responses of crypt-derived organoids embedded in collagen versus Matrigel, and their transcriptomic comparison with villus-derived organoids

ABSTRACT: We compared the effects of 5-fluorouracil (5-FU) on gene expression profiles of mouse crypt-derived intestinal organoids embedded in either Matrigel (MG) or collagen type I (COL). Distinct sets of genes were upregulated in COL-embedded organoids following 5-FU treatment, suggesting that collagen-based ECM uniquely modulates inflammatory and DNA-damage responses. We further compared COL-embedded crypt-derived organoids with COL-embedded villus-derived organoids (V-organoids) and found that their transcriptional profiles were highly similar. These results indicate that collagen embedding promotes the emergence of revival stem cell–like signatures regardless of the cellular origin of the organoids.

Gene expression profiles of intestinal organoids under collagen/Matrigel culture and 5-fluorouracil treatment in human

Project description:In this study, we examined how 5-fluorouracil (5-FU) treatment modulates transcriptional programs in human intestinal organoids cultured in Matrigel or collagen matrices. By comparing Matrigel-embedded and collagen-embedded organoids under control and 5-FU–treated conditions, we identified ECM-dependent and treatment-specific gene expression changes associated with cellular stress responses, epithelial regeneration, and matrix-driven phenotypic differences.

RNA-seq of wildtype mouse small intestinal organoids grown in Matrigel or in/on collagen.

Project description:We aimed to analyse the effect of different extra-cellular matrices on the growth of small intestinal organoids. Small intestinal crypts of wildtype mice were harvested and grown under standard Matrigel organoid conditions. After establishment of organoids (passaged 1-2), organoids were grown in Matrigel, on collagen or in a drop of collagen. Growth in a droplet of collagen requires addition of Wnt3a, therefore all samples are either provided with standard culture conditions (ENR) or with ENR+50%Wnt3a-CM (WENR). Samples were grown in specified matrix for at least 1-2 passages before RNA was purified.

Single-cell RNA-sequenceing analysis of mouse intestinal organoids cultured in Matriel or type I collagen

Project description:Intestinal epithelial regeneration depends on cellular plasticity under inflammatory conditions. Two major forms of plasticity have been described: spatial plasticity, in which mature cells dedifferentiate into crypt base columnar (CBC) stem cells, and fetal reversion, where cells adopt a fetal-like transcriptional state. To investigate the cellular mechanisms underlying these processes, we performed single-cell RNA sequencing on mouse intestinal epithelial organoids cultured in either Matrigel or collagen-based matrices. Combined single-cell transcriptomic and functional analyses revealed bidirectional interconversion between CBCs and revival stem cells (revSCs), as well as the reprogramming of absorptive enterocytes toward revSC-like states. This dataset provides a high-resolution atlas of epithelial stem cell states and plasticity transitions, facilitating further investigation of regenerative hierarchies in the mouse intestine.

Tissue extracellular matrix hydrogels as alternative to Matrigel for culturing gastrointestinal organoids

Project description:Matrigel, a mouse tumor extracellular matrix (ECM) protein mixture, is an indispensable component of most organoid tissue culture. However, it has limited the utility of organoids for drug development and regenerative medicine due to its tumor-derived origin, batch-to batch variation, high cost, and safety issues. Here, we demonstrate that gastrointestinal (GI) tissue-derived ECM hydrogels are a suitable substitute for Matrigel in GI organoid culture. We found that the development and function of GI organoids grown in GI ECM hydrogels are comparable or often superior to those in Matrigel. In addition, GI ECM hydrogels enabled long-term subculture and transplantation of GI organoids by providing GI tissue-mimetic microenvironments. Tissue-specific and age-related ECM profiles of GI ECM hydrogels that affect organoid development were also elucidated through proteomic analysis. Together, our results suggest that ECM hydrogels derived from decellularized GI tissues are an effective alternative to the current gold standard, Matrigel, and produce organoids suitable for GI disease modeling, drug development, and tissue regeneration.

RNA-Seq of human spinal cord organoids generated in Matrigel and alginate

Project description:This experiment compares the transcriptome profile of human spinal cord organoids generated from iPSCs in Matrigel, 1% alginate hydrogel, or 2% alginate hydrogel. Spinal cord organoids were generated from human iPSCs and then encapsulated in the respective hydrogels before further maturation. Organoids were harvested on days 30, 60, and 90 for each group. In addition to the differences between hydrogel groups, neuronal and glial markers at each time point were also assessed for the development of the organoids.

Single cell RNA-seq of hiPSC-derived kidney organoids differentiated within self-assembling peptide hydrogels and the animal-derived matrix Matrigel

Project description:scRNA-seq was used to characterise hiPSC-derived kidney organoids differentiated within fully synthetic self-assembling peptide hydrogels of variable mechanical strengths and compare these to organoids differentiated within the animal-derived matrix, Matrigel. Organoids were matured in the respective matrices until day 24 of differentiation and 6 organoids per support matrix were then pooled and dissociated using the cold-active protease from Bacillus licheniformis. Cells were processed on the 10x Genomics Chromium platform using the Single-Cell 3’ v3.1 protocol. The NextSeq500 (Illumina) was used to sequence the libraries generated and initial processing of the data was carried out using the 10X Genomic Cell Ranger v3.1.0 pipeline.

Gene expression profiles of HYDROX-cultured human liver organoids compared to those of Matrigel-cultured human liver organoids.

Project description:Human liver organoids, an in vitro 3D culture system to recapitulate biological tissue, are expected to be used for drug discovery. However, Matrigel, the most widely used extracellular matrix for organoid culture, has concerns about safety and reproducibility since it is murine-derived. Morever, low hepatic functions of human liver organoids compared to primary human hepatocytes is considered a challenge. Herein, we attempted to culture human liver organoids, established from primary (cryopreserved) human hepatocytes (PHH), using HYDROX, a chemically defined 3D nanofiber. While proliferative capacity of human liver organoids was lost by HYDROX-culture, the gene expression level of a hepatocyte marker CYP3A4 and the CYP3A4 metabolic activity in HYDROX-cultured liver organoids were significantly improved, comparable to those of PHH. HYDROX-cultured liver organoids when treated with hepatotoxic drugs such as acetaminophen showed similar cell viability to that of PHH, suggesting that HYDROX-cultured liver organoids could be applied to drug-induced hepatotoxicity test. Furthermore, HYDROX-cultured liver organoids maintained its functions for up to 35 days and could be used to estimate chronic drug-induced hepatotoxicity such as those of fialuridine. Our findings demonstrated that human liver organoids obtained high liver functions by HYDROX-culture, meaning that HYDROX could contribute to drug discovery as a novel biomaterial.

iPSC-derived type IV collagen α5-expressing kidney organoids model Alport syndrome

Project description:Alport syndrome (AS) is a hereditary glomerulonephritis caused by COL4A3, COL4A4 or COL4A5 gene mutations and characterized by abnormalities of glomerular basement membranes (GBMs). Due to a lack of curative treatments, the condition proceeds to end-stage renal disease even in adolescents. Hampering drug discovery is the absence of effective in vitro methods for testing the restoration of normal GBMs. Here, we aimed to develop kidney organoid models from AS patient iPSCs for this purpose. We established iPSC-derived collagen α5(IV)-expressing kidney organoids and confirmed that kidney organoids from COL4A5 mutation-corrected iPSCs restore collagen α5(IV) protein expression. Importantly, our model recapitulates the differences in collagen composition between iPSC-derived kidney organoids from mild and severe AS cases. Furthermore, we demonstrate that a chemical chaperone, 4-phenyl butyric acid, has the potential to correct GBM abnormalities in kidney organoids showing mild AS phenotypes. This iPSC-derived kidney organoid model will contribute to drug discovery for AS.
