Project description:We show that Retinal pigment epithelium (RPE) secreted-factor, pigment epithelium derived factor (PEDF) secreted/derived from primary or iPSC-derived retinal pigment epithelium (RPE)RPE, dramatically inhibitsed the cell growth of iPSCs. PEDF was detected abundantly in culture supernatant media of primary and iPSC-derived RPE. We examined the gene expression in primary RPE and iPS-derived RPE. Two samples: RPE derived from 253G1 iPSC, Primary RPE.

Project description:We generated hiPSCs from patients fibloblast with retinitis pigmentosa (RP) using retrovirus and Sendai virus vectors, which we differentiated into hiPSC derived retinal pigment epithelium using two different methods (SDIA and SFEB methods). We investigated whether these hiPSC-RPE colonies, which were differentiated from various cell lines and methods, showed similar gene expression patterns to those of native RPE. We classified hiPSC-RPE, hiPSCs, and fibroblasts from RP patients, hRPE (commercially available human fetal RPE, Lonza) , ARPE19 (a human RPE cell line), and other human tissues from 54,675 probe sets using microarray data.

Project description:The retinal pigment epithelium (RPE) is a polarized cell layer that is critical for photoreceptor function and survival. It’s unique relationship to the photoreceptors and its specific physiology makes the RPE a critical determinant of human vision. Therefore we performed global expression profiling of native and cultured human fetal and adult RPE and determined a unique set of highly-expressed genes (called the “signature” set) by comparing the observed RPE gene profiles to the Novartis expression database (SymAtlas: http://wombat.gnf.org/index.html) of 78 tissues.

Project description:The retinal pigment epithelium (RPE) is a polarized cell layer that is critical for photoreceptor function and survival. Itâs unique relationship to the photoreceptors and its specific physiology makes the RPE a critical determinant of human vision. Therefore we performed global expression profiling of native and cultured human fetal and adult RPE and determined a unique set of highly-expressed genes (called the âsignatureâ set) by comparing the observed RPE gene profiles to the Novartis expression database (SymAtlas: http://wombat.gnf.org/index.html) of 78 tissues. A comparative analysis of transcriptomes from human fetal and adult RPE, primary cultures and commonly-used cell lines was performed. Using selection criteria of at least 10-fold higher expression in each of three RPE preparations, we identified 154 RPE signature genes, which were validated by qRT-PCR analysis in RPE and in an independent set of 11 tissues.

Project description:Compare transcriptomes of control and USH1B patient iPSC-derived retinal pigment epithelium (RPE) to elucidate disease mechanisms of Usher syndrome type IB (USH1B). USH1B patient fibroblasts were collected at Great Ormond Street Hospital (GOSH) and reprogrammed to iPSCs. Control and patient iPSCs differentiated in vitro to generate retinal pigment epithelium (RPE) and collected for RNA-seq at 24 week. Sequencing was performed at University College London (UCL) Genomics on a NovaSeq 6000 system. Data aligned to the human genome UCSC hg38 using RNA-STAR 2.5.2b.

Project description:The developmental pathway of the neural retina (NR) and retinal pigment epithelium (RPE) has been revealed by extensive research in mice. However, the molecular mechanisms underlying the development of the human NR and RPE, as well as the interactions between these two tissues, have not been well defined. Here, we analyzed 2,421 individual cells from human fetal NR and RPE using single-cell RNA sequencing (RNA-seq) technique and revealed the tightly regulated spatiotemporal gene expression network of human retinal cells. We identified major cell classes of human fetal retina and potential crucial transcription factors for each cell class. We dissected the dynamic expression patterns of visual cycle and ligand-receptor interaction related genes in the RPE and NR. Moreover, we provided a map of disease-related genes for human fetal retinal cells and highlighted the importance of retinal progenitor cells as potential targets of inherited retinal diseases. Our findings captured the key in vivo features of the development of the human NR and RPE and offered insightful clues for further functional studies.

Project description:The microarray technique was used to investigate gene expression level changes in human retinal pigment epithelium (RPE) microdissected from fetal eyes (13 and 16 weeks of gestation) and adult eyes (40-60 years old). The gene expression analysis of human fetal RPE during development were performed and compared to human native RPE. Of the 45,033 probe sets on the microarray, 30,736 were detected. 3498 differentially expressed genes could be clustered into 8 patterns of expression that were statistically significant. Analyzing expression pattern of genes coding for key functions (pigment synthesis, visual cycle, phagocytosis, adherens and tight junction, transcellular transport) indicates human RPE achieved a high degree of maturity at early pregnancy. Compare to 154 signature genes of RPE, 148 candidate genes were identified in this studies including 53 down-regulated genes and 5 up-regulated genes. qRT2-PCR results showed similar expression trends with the microarray at three time points.These findings indicate human RPE has different expression pattern compared to other animals. A three chip study using total RNA pooled equally from three 13-week fetal eyes, two 16-week fetal eyes and two adult eyes for three time points (13, 16 week gestation and mature adult eye). Experiment was repeated in another group samples. This is a six chip study totally.

Project description:To evaluate the effect of oxidative stress on transcript localization in the retinal pigment epithelium (RPE), we performed poly-A RNA sequencing on nuclear and cytoplasmic fractions from induced pluripotent stem cell-derived retinal pigment epithelium (iPSC-RPE) cells exposed to hydrogen peroxide, as well as untreated controls.
