RNA sequencing of human brain organoids to evaluate sex-specific and opto-FGFR-mediated responses to Simplified 5 Ion GCR Simulation

ABSTRACT: This study aims to characterize transcriptomic responses to Simplified 5 Ion GCR Simulation (simGCRsim) in human brain organoids derived from hiPSCs. Two independent RNA-seq experiments were conducted. The first set compared male- and female-derived organoids to evaluate sex-specific transcriptional responses to GCR. The second set assessed organoids derived from i) male hiPSCs expressing optogenetically-controlled FGFR (opto-FGFR) or mock constructs to explore FGFR signaling as a potential countermeasure and ii) one female hiPSC line (SC2131), with or without GCR exposure. Together, these datasets provide insight into both intrinsic sex differences and FGFR-dependent protective mechanisms in human neural tissues in the context of space radiation exposure.

Gene expression analysis of hiPSC-derived renal angiomyolipoma organoids

Project description:Angiomyolipomas (AMLs) are the most common renal manifestation in patients with Tuberous Sclerosis Complex. The recapitulation of AMLs experimentally has remained a challenge, precluding the study of tumor mechanisms. Here we used Next-Generation Sequencing to analyze the transcriptomes of renal organoids derived from TSC2-/-, TSC2+/- or TSC2+/+ human induced pluripotent stem cells (hiPSCs) derived from a patient diagnosed with Tuberous Sclerosis Complex. Organoids derived from TSC2-/- hiPSCs but not from isogenic TSC2+/- or TSC2+/+ hiPSCs shared a common transcriptional signature and a myomelanocytic cell phenotype with kidney AMLs.

Microarray-based Gene Expression Analysis of human cerebral organoids from urinary epithelial cells

Project description:Analysis of human cerebral organoids developed from both WA09 human embryonic stem cells and human urinary epithelial cell derived hiPSCs. The hypothesis tested was that organoids developed from human urinary epithelial cell derived hiPSC have similar gene expression patterns as WA09 derived organoids subjected to the same organoid development process.

Human iPSC-derived renal collecting duct organoids model cystogenesis in ADPKD

Project description:Here, establishing expansion cultures of hiPSC-derived ureteric bud tip cells, an embryonic precursor that gives rise to collecting ducts, we succeeded in advancing the developmental stage of collecting duct organoids and showed that all collecting duct organoids derived from PKD1-/- hiPSCs spontaneously develop multiple cysts, clarifying the initiation mechanisms of cystogenesis.

Hepatotoxicity evaluation of co-exposure of microplastics and TBBPA by 3D biofabricated multicellular organoids

Project description:We combined human induced pluripotent stem cells (hiPSCs) and 3D printing to mass-produced liver Disse space-like organoids in microspheres hydrogels (DOs). After 5 days of co-culture, the cells within the microspheres were aggregated and developed into liver organoids, composed of iPSC-derived hepatocytes, endothelial cells, and hepatic stellate cells (LX2). These organoids mirrored the hepatotoxicity of polystyrene microplastics (PS-MPs), TBBPA, and complexes MPTA with healthy and patient-derived organoids.

Mesenchymal stem/stromal cells from human pluripotent stem cell-derived brain organoid enhance the ex vivo expansion and maintenance of hematopoietic stem/progenitor cells

Project description:We report a novel method for harvesting MSCs from 3D human brain organoids under serum-free culture condition. The stromal cells, derived from both H1-hESCs and human induced pluripotent stem cells (hiPSCs) forebrain organoids, were capable of differentiating into the classical mesenchymal-derived cells (osteoblasts, chondrocytes, and adipocytes). These cells expressed MSC markers, thus named pluripotent stem cell-derived MSCs (pMSCs).To investigate the role of pMSCs, we compared the RNA sequencing of pMSCs ,umbilical cord-MSC,hiPSCs and H1 hESCs.To investigate the function pMSC in the regulation of umbilical cord blood HSPCs, we compared the RNA sequencing of CD34+ cells after co-culturing with and without pMSC and UC-MSCs,respectively.We then performed gene expression profiling analysis using data obtained from RNA-seq of 9 kinds of different cells.

Genetically engineering self-organization of human pluripotent stem cells into a liver bud-like tissue using Gata6

Project description:Human induced pluripotent stem cells (hiPSCs) have potential for personalized and regenerative medicine. While most methods of utilizing these cells have focused on deriving homogenous populations of specialized cells, there has been modest success in producing hiPSC-derived organotypic tissues or organoids. Here we present a novel approach for generating and then co-differentiating hiPSC-derived progenitors. With a genetically engineered pulse of GATA6 expression, we initiate rapid emergence of all three germ layers as a complex function of GATA6 expression levels and tissue context. Within two weeks we obtain a complex tissue that recapitulates early developmental processes and exhibits a liver bud-like phenotype, including haematopoietic and stromal cells, as well as a neuronal niche. Our approach addresses two major issues in derivation of tissues from hiPSCs: using a single autologous hiPSCs as source and generating a range of stromal cells that co-develop with parenchymal cells to form complex tissues. Gene expression profiling (microarray) of iPS cells (PGP1) at X days post- doxycycline induction of mouse Gata6. Either total cells or immunomagnetic isolation of cells with specific surface markers. Three samples per group.
