(Submitter supplied) Retinal pigment epithelium (RPE) cells can be obtained through in vitro differentiation of both embryonic stem cell (ESC) and induced pluripotent stem cells (iPSC) for cell replacement therapy. We have previously identified 87 signature genes relevant to RPE cell differentiation and function through transcriptome analysis of both human ESC- and iPSC-derived RPE as well as normal fetal RPE. Here, we profiled miRNA expression through small RNA-seq in human ESCs and their RPE derivatives. more...

(Submitter supplied) Using the paradigm of in vitro differentiation of hESCs/iPSCs into retinal pigment epithelial (RPE) cells, we have recently profiled mRNA and miRNA transcriptomes to define a set of RPE mRNA and miRNA signature genes implicated in directed RPE differentiation. In this study, in order to understand the role of DNA methylation in RPE differentiation, we profiled genome-scale DNA methylation patterns using the method of reduced representation bisulfite sequencing (RRBS). more...

(Submitter supplied) Retinal pigment epithelial cells differentiated from human induced pluripotent stem cells (hiPSCs), called iRPE, are being explored as a cell-based therapy for the treatment of retinal degenerative diseases, especially age-related macular degeneration (AMD). The success of RPE implantation is believed to be linked to the use of biomimetic scaffolds that simulate Bruch’s membrane and aid in its maturation and integration. more...

(Submitter supplied) Retinal pigment epithelium (RPE) cells show heterogeneous level of pigmentation when cultured in vitro. We used Automated Live imaging and cell Picking System (ALPS) with single cell RNA sequencing (scRNA-seq) to analyze the correlation between color intensities and gene expression profiles of human-induced pluripotent stem (iPS) cell-derived RPE cells.

(Submitter supplied) The retinal pigment epithelial (RPE) cell line ARPE-19 provides a widely-used alternative to native RPE. However, retention of the native RPE phenotype becomes problematic after multiple passages. We wished to determine if suitable culture conditions and differentiation could restore RPE-appropriate gene expression to ARPE-19. ARPE-19 cells at passages p9 to p12, grown in DMEM containing high glucose and pyruvate with 1% fetal bovine serum, were differentiated for up to 4 months. more...

(Submitter supplied) Age-related macular degeneration is a progressive disease resulting in impaired central vision. Degeneration of the retinal pigmented epithelial (RPE) monolayer is associated with the progression of the disease. To date no treatment is able to stop this progression, however new cell replacement studies using human embryonic stem cells (hESC) to generate RPE show a promising prospective. To improve cell replacement strategies a better understanding about the development of RPE cells is necessary. more...

(Submitter supplied) Retinal Pigment Epithelium (RPE) derived from two human embryonic stem cell lines, H1 and H9, were compared with human fetal RPE (hfRPE) using RNA-seq. Nominally, the transcriptome of H1-derived RPE showed greater overlap with hfRPE. For cells maintained in the medium used to differentiate RPE, 6.2% (H1-RPE) and 4.2% (H9-RPE) of the transcripts were expressed in amounts that were statistically different from hfRPE (false discovery rate: 5%). more...

(Submitter supplied) To assess the geome-wide similarities between primary fetal retinal pigmented epithelium (RPE) and stem-cell derived RPE, we performed whole genome microarray expression on primary RPE and both embryonic stem cell (ESC) derived RPE and induced pluripotent stem cell (iPSC) derived RPE. We found ES-derived RPE better resembles fetal RPE than iPS-derived RPE.

(Submitter supplied) Dysfunction of the retinal pigmented epithelium (RPE) results in degeneration of photoreceptors and vision loss and is correlated with common blinding disorders in humans. Although many protein-coding genes are known to be expressed in RPEs and important for their development and maintenance, virtually nothing is known about the in vivo roles of non-protein coding transcripts in RPEs. The expression patterns of microRNAs (miRNAs) have been analyzed in a variety of ocular tissues, and few were implicated to play role in RPE based on studies in cell lines. more...

(Submitter supplied) Comparing iPS derived RPE cells from human AMD and non-AMD donors It has been a challenge to model retinal disorders such as geographic atrophy (GA) in in vivo animals, primarily because several factors, including genetics and aging itself, contribute to disease phenotype of age-related macular degeneration (AMD). We generated retinal pigment epithelial (RPE) cells from patients with advanced AMD and assessed their ability to model disease. more...

(Submitter supplied) 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.

(Submitter supplied) Human ESCs are pluripotent cells that have the capacity of self renewal for a prolonged period in vitro, and can differentiate into derivatives of all three primary germ layers: endoderm, mesoderm and ectoderm. Human ESCs are responsive to a wide range of factors in vitro that can direct their differentiation into specific cell types. We analyzed the effect of nicotinamide (NIC) on differentiation of hESCs in vitro. more...

(Submitter supplied) 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. more...

(Submitter supplied) We evaluate whether human induced pluripotent stem cell-derived retinal pigment epithelium (iPSC-RPE) cells can be used to prioritize and functionally characterize causal variants at age-related macular degeneration (AMD) risk loci. We generated iPSC-RPE from six subjects and show that they have morphological and molecular characteristics similar to native RPE. We generated RNA-seq, ATAC-seq, and H3K27ac ChIP-seq data and observe high similarity in gene expression and enriched transcription factor motif profiles between iPSC-RPE and human fetal-RPE. more...
