Project description:To gain insights into which pathways might be dysregulated in JMML, we compared the transcriptome profiles among hiPSC and sorted CD33+ myeloid cells from control and patient samples. NS/JMML-derived CD33+ myeloid cells showed dysregulation in major biological processes. Moreover, a consistent expression pattern among sets of genes related to pluripotency and myeloid regulation was observed in the control, NS and NS/JMML CD33+ myeloid cells further supporting generally successful myelopoiesis. Total RNA obtained from hiPSC and sorted CD33+ myeloid cells (at day 14 of differentiation) from control and patient samples

Project description:MLL-AF4+ blasts from infant B-ALL, CB-derived CD34+CD38-CD19-CD33- HSC, CB-derived CD34+CD19+CD33- B-cell HPCs and CB-derived CD34+CD33+CD19- myeloid HPCs. We used microarray to estudy gene expression profile comparing ALL vs HSC, HPC and myeloid HPSC.

Project description:MLL-AF4+ blasts from infant B-ALL, CB-derived CD34+CD38-CD19-CD33- HSC, CB-derived CD34+CD19+CD33- B-cell HPCs and CB-derived CD34+CD33+CD19- myeloid HPCs. We used microarray to estudy gene expression profile comparing ALL vs HSC, HPC and myeloid HPSC. We used highly FACS-purified (purity>98%) MLL-AF4+ blasts from infant B-ALL, CB-derived CD34+CD38-CD19-CD33- HSC, CB-derived CD34+CD19+CD33- B-cell HPCs and CB-derived CD34+CD33+CD19- myeloid HPCs. For each independent sample technical duplicates were always performed. Total RNA was extracted using TRIol reagent, and quantified on a Nanodrop spectrophotometer and Bioanalyzer. High-quality RNA was reverse transcribed and the obtained cDNA was used as a template to synthesize biotinylanted cDNA, then was fragmented and hybridized as duplicates/triplicates to HG-U133 plus2.0 GeneChips (Affymetrix) according to manufacturer's guideline.

Project description:Human induced pluripotent stem cells (hiPSCs) constitute an important breakthrough in regenerative medicine, particularly in orthopedics, where more effective treatments are urgently needed. Despite the promise of hiPSCs only limited data on in vitro chondrogenic differentiation of hiPSCs are available. Therefore, we compared the gene expression profile of pluripotent genes in hiPSC-derived chondrocytes (ChiPS) to that of an hiPSC cell line created by our group (GPCCi001-A).

Project description:Skeletal muscle research is transitioning towards 3D tissue engineered in vitro models reproducing muscle’s native architecture and supporting measurement of functionality. Human induced pluripotent stem cells (hiPSCs) offer high yields of cells for differentiation. It has been difficult to differentiate high quality, pure 3D muscle tissues from hiPSCs that show contractile properties comparable to primary myoblast-derived tissues. Here, we present a transgene-free method for the generation of purified, expandable myogenic progenitors (MPs) from hiPSCs grown under feeder-free conditions. We defined a protocol with optimal hydrogel and medium conditions that allowed production of highly contractile 3D tissue engineered skeletal muscles with forces similar to primary myoblast-derived tissues. Gene expression and proteomic analysis between hiPSC-derived and primary myoblast-derived 3D tissues revealed a similar expression profile of proteins involved in myogenic differentiation and sarcomere function. The protocol should be generally applicable for the study of personalized human skeletal muscle tissue in health and disease.

Project description:We successfully induced corneal epithelial cells from human iPSCs. Then, we perfomed global expression analysis using microarray to compare the character of hiPSC-derived corneal epithelial cells with that of the other kinds of cells. Total RNA was obtained from human iPSCs (hiPSCs), human iPSC-derived corneal epithelial cells (hiCECs), human corneal limbal epithelial cells (HCECs), human oral keratinocytes (HOKs), human dermal fibroblasts (HDFs) and six weeks-differentiated hiPSCs (hiPSC-derived ocular surface ectoderm, OSE) using the QIAZol reagent. A microarray analysis using Sure Print G3 human 8x60K slides (Agilent technologies) was performed at Takara Bio (Shiga, Japan).

Project description:To incorporate Kupffer cells into hiPSC-LOs, we differentiated erythro-myeloid progenitors (EMPs) from hiPSCs. We compares the gene expression profiles of hiPSC-EMPs with cord-blood hematopoietic stem and progenitor cells (CB-HSPCs); and EMP-generated Kupffer cells (EMP-KC) with human primary Kupffer cells.

Project description:Schizophrenia is a debilitating neurological disorder for which no cure exists. Few defining characteristics of schizophrenic neurons have been identified and the molecular mechanisms responsible for schizophrenia are not well understood, in part due to the lack of patient material for study. Human induced pluripotent stem cells (hiPSCs) offer a new strategy for studying schizophrenia. We have created the first cell-based human model of a complex genetic psychiatric disease by generating hiPSCs from schizophrenic patients and subsequently differentiating these cells to hiPSC-derived neurons in vitro. Schizophrenic hiPSC-derived neurons showed diminished neuronal connectivity in conjunction with decreased neurite number, PSD95-protein levels and glutamate receptor expression. Gene expression profiles of schizophrenic hiPSC-derived neurons identified altered expression of many components of the cAMP and WNT signaling pathways. Key cellular and molecular elements of the schizophrenic phenotype were ameliorated following treatment of schizophrenic hiPSC-derived neurons with the antipsychotic loxapine. 3 independent differentiations (biological replicates) for each of four control and four schizophrenic patients were analyzed.
