Project description: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.
Project description:Human neuroblatoma cell lines (N=25) and retinal pigmented epithelium cell lines (N=4) were analyzed for gene expression under untreated/baseline growth conditions. Expression profiling and characterization of a set of Neuroblastoma and retinal pigmented epithelium cell lines
Project description: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. Gene expression was measured in primary fetal RPE, ES-derived RPE, iPS-derived RPE. ES cells and BJ fibroblasts were used as controls.
Project description:Study the gene expression profiling of human retinal pigmented epithelium cell line ARPE-19 treated with or without human recombinant Cochlin protein for 24 hours.
Project description:Microarray study comparing trabecular meshwork-derived cells (TMDCs) from the iridocorneal angle of the human eye, with other human cell types such as scleral fibroblasts, corneal fibroblasts, retinal pigmented epithelial (RPE) cells, corneal stroma, human embryonic stem cells (hESC), neural precursors differentiated from hESC, human umbilical vein endothelial (HUVEC) cells and human adipose-tissue-derived mesenchymal stromal cells (MSC)
Project description:To characterize gene expression changes in mice following serous retinal detachments, we employed whole genome microarray expression profiling as a tool to identify genes with the potential effects on the neural retina as well as retinal pigmented epithelium. Total RNA was harvested from nm3342 (mutant) and age-matched wild-type (C57Bl/6J) mice at P30 or P365 for examination using microarray analysis. Retinas and retinal pigmented epithelium was harvested from both age-matched mutant and wild-type mice.
Project description:The pigmented portion of ciliary epithelium in the adult mammalian eye harbors mitotically quiescent retinal sphere cells, which are capable of self-renewal and differentiating into retinal neurons when assayed in vitro; however, very little is known about the molecular mechanism controlling the proliferation and differentiation of these adult retinal stem cells or their molecular resemblance to mutipotent stem/progenitor cells during early eye development. This experiment studies the gene expression of first passage and primary human and mouse retinal sphere cells. Experiment Overall Design: this experiment include 4 samples and 12 replicates
Project description: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. In the current study we therefore do extensive genetic profiling of hESC derived RPE cells at different stages during development based on their pigmentation.
