Vascular organoids differentiation from human induced pluripotent stem cells (iPSC)

Project description:We have established a vascular organoid culture system with self-assembled endothelial networks that are covered by a basement membrane and pericytes. CD31+ endothelial cells, and CD140b positive pericytes were FACS sorted and RNA-seq was performed.

Proteomic analysis of induced pluripotent stem cell-derived kidney organoids

Project description:Kidney organoids were generated from a control iPSC line using a previously published protocol (https://doi.org/10.1038/nprot.2016.098). Organoids were collected at three timepoints during the protocol (day 14, 18 and 25) and prepared for proteomic analyses. The focus of the study was to define the proteomic composition of kidney organoids during differentiation with a particular emphasis on the extracellular matrix and its comparison to in vivo systems. Following a ample fractionation and matrix enrichment strategy, samples were prepared for high resolution label-free tandem mass spectrometry to define the proteomic composition of human kidney organoids.

Proteomics characterisation of induced pluripotent stem cells and cortical brain organoids.

Project description:A method was developed to reproducibly produce neural retina and cortical brain regions from confluent cultures of stem cells. The spontaneously generated cortical organoids were isolated and cultured in suspension conditions for maturation. Proteomic analysis of both the original induced pluripotent stem cells and the cortical organoids demonstrated the increased presence of synaptic components, indicating maturity.

Patient-iPSC-derived kidney organoids show functional validation of a ciliopathic renal phenotype

Project description:Purpose: A proof of concept study examining the disease modelling capabilities of patient iPSC derived kidney organoids. Methods: A proband was diagnosed by genome sequencing with compound heterozygous IFT140 mutations. A one-step reprogramming/gene-editing protocol of proband fibroblasts was used to derive both uncorrected patient and isogenic gene-corrected induced pluripotent stem cells (iPSC) which were differentiated to kidney organoids. Organoids were examined by immunofluorescence. Additionally, epithelial cells magnetically sorted from whole kidney organoids underwent transcriptional profiling and spheroid culture. Results: Differential expression analysis of organoid epithelial cell fractions demonstrated apicobasal polarity, cell-cell junction and dynein motor assembly downregulation in patient organoids. Defective ciliary morphology and spheroid culture were rescued in gene corrected organoids. Conclusions: This study validates patient iPSC-derived kidney organoids as a novel, faithful and patient-specific model to further the study of inherited renal disease in regenerated, human, in vitro tissue.

1H NMR metabolite monitoring during the differentiation of human induced pluripotent stem cells provides new insights into the molecular events that regulate embryonic chondrogenesis

Project description:The integration of cell metabolism with signalling pathways, transcription factor networks and epigenetic mediators is critical in coordinating molecular and cellular events during embryogenesis. Induced pluripotent stem cells (IPSCs) are an established model for embryogenesis, germ layer specification and cell lineage differentiation, advancing the study of human embryonic development and the translation of innovations in drug discovery, disease modelling and cell-based therapies. The metabolic regulation of IPSC pluripotency is mediated by balancing glycolysis and oxidative phosphorylation, but there is a paucity of data regarding the influence of individual metabolite changes during cell lineage differentiation. We used <sup>1</sup>H NMR metabolite fingerprinting and footprinting to monitor metabolite levels as IPSCs are directed in a three-stage protocol through primitive streak/mesendoderm, mesoderm and chondrogenic populations. Metabolite changes were associated with central metabolism, with aerobic glycolysis predominant in IPSC, elevated oxidative phosphorylation during differentiation and fatty acid oxidation and ketone body use in chondrogenic cells. Metabolites were also implicated in the epigenetic regulation of pluripotency, cell signalling and biosynthetic pathways. Our results show that <sup>1</sup>H NMR metabolomics is an effective tool for monitoring metabolite changes during the differentiation of pluripotent cells with implications on optimising media and environmental parameters for the study of embryogenesis and translational applications.

Lineage recording in human cerebral organoids (whole organoids)

Project description:Induced pluripotent stem cell (iPSC) derived organoid systems provide models to study human organ development. Single-cell transcriptome sequencing enables highly-resolved descriptions of cell state heterogeneity within these systems and computational methods can reconstruct developmental trajectories. However, new approaches are needed to directly measure lineage relationships in these systems. Here we establish an inducible dual channel lineage recorder, iTracer, that couples reporter barcodes, inducible CRISPR/Cas9 scarring, and single-cell transcriptomics to analyze state and lineage relationships in iPSC-derived systems. This data set include the iTracer data of 12 cerebral organoids.

Single cell analysis of iPSC-derived midbrain organoids (GBA1 mutant and controls)

Project description:Mutations in the lysosomal enzyme β-glucocerebrosidase (GCase), which cause Gaucher´s disease, are the most frequent genetic risk factor for Parkinson’s disease (PD). Here, we employed single-cell genomic approaches in induced pluripotent stem cell (iPSC)-derived midbrain organoids to dissect the mechanisms underlying GCase-related neurodegeneration.

Hepatic differentiation of liver organoids

Project description:We analyzed gene expression profiles of self-organizing, multi-cellular, 3D liver organoids derived by co-culture of induced Pluripotent Stem Cell and stromal progenitors. We report the RNA-seq results of liver organoid at day0, day2, day4, day6 of co-culture. We also report RNA-seq results of constituent of the liver organoid, which are human iPSC at hepatic specification stage, human Mesenchymal stem cells derived from bone marrow, human umbilical vein endothelial cell. As controls, we also report RNS-seq results of un-differentiated human iPSC, human iPSC at definitive endoderm stage, human liver tissue, and primary cultured human hepatocytes isolated from unused donor livers.
