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.

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.

Proteomic signatures of schizophrenia-sourced iPSC-derived brain organoids

Project description:Schizophrenia is a complex and severe neuropsychiatric disorder, with a wide range of debilitating symptoms. Several aspects of its multifactorial complexity are still unknown, and some are accepted to be an early developmental deficiency with a more specifically neurodevelopmental origin. Understanding timepoints of disturbances during neural cell differentiation processes could lead to an insight into the development of the disorder. In this context, human brain organoids and neural cells differentiated from patient-derived induced pluripotent stem cells are of great interest as a model to study the developmental origins of the disease. Here we evaluated the differential expression of proteins of schizophrenia patient-derived neural progenitors, early neurons, and brain organoids. Using bottom-up shotgun proteomics with a label-free approach for quantitative analysis. Multiple dysregulated proteins were found in pathways related to synapses, in line with postmortem tissue studies of schizophrenia patients. However, organoids and immature neurons exhibit impairments in pathways never before found in patient-derived induced pluripotent stem cell studies, such as spliceosomes and amino acid metabolism. In conclusion, here we provide comprehensive, large-scale, protein-level data that may uncover underlying mechanisms of the developmental origins of schizophrenia.

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.
