Project description: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%). After adaptation to the serum-free medium, SFM-1, only 1.0 % (H1-RPE) and 1.9% (H9-RPE) were expressed in amounts that were statistically different. For RPE signature genes, statistical differences were observed for 1.0 % (H1-RPE) and 1.9% (H9-RPE) of the transcripts. For some barrier-function related mRNAs the statistical differences were greater than these small differences would predict. For adhesion proteins and plasma membrane transporters, the differences were as great as 6.9% and 4.3%, respectively. After adaptation to SFM-1, the statistical differences between H1- and H9-RPE were only 0.4% for all transcripts, 1.4% for signature genes, and 0.7% for membrane transporters. No statistical differences were observed for the transcripts related to tight junctions, adhesion junctions or ion channels. In summary, SFM-1 promoted the maturation of stem cell-derived RPE, and the statistical difference between two stem cell lines was minimal. RNA sequencing of hfRPE from three fetuses (reference sample) and three independent isolates of RPE derived from the H1, and three from the H9, human embryonic stem cell (hESC) lines. The cultures were maintained in a serum-free medium, SFM-1. Comparisons were also made to cultures maintained in the medium used to differentiate the cells, KSR.

Project description:To investigate the tRF/tiRNA expression pattern in the development of choroidal neovascularization, we built a laser-induced choroidal neovascularization mouse model and performed the tRF/tiRNA sequencing on RPE-choroid-sclera complexes at different time points after model establishment, while the tissues from mice without treatment were used as control group.

Project description:Retinal Pigment Epithelial (RPE) cells are located behind the retina and are critical for photoreceptor survival. Loss of RPE is associated with several pathogenic conditions such as Age Related Macular Degeneration and Retinitis Pigmentosa. RPE derived from human embryonic stem cells (hESC) offer a potential source for producing these cells for therapy. Here we report the molecular and cellular characterization of RPE differentiated from hESC. hESC derived RPE are capable of proliferation and lose their epithelial characteristics before becoming confluent and re-differentiating back into their typical pigmented, cobblestoned appearance. During the proliferative phase, they adopt a mesenchymal morphology and express mesenchymal markers. Our results demonstrate that this apparent Epithelial-Mesenchymal Transition is not regulated by the classical EMT transcription factors SNAIL and SLUG. Furthermore, it is possible to regulate RPE de-differentiation and re-differentiation by modulating the Wnt and BMP pathway respectively. These findings further our understanding of the genesis and expansion of RPE which is essential for their therapeutic use.

Project description: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. Herein, through RPE specific conditional mutagenesis of Dicer1 or DGCR8, the importance of miRNA for RPE differentiation was uncovered. Interestingly, miRNAs were found to be dispensable for maintaining the RPE fate and survival, and yet they are essential for acquisition of important RPE properties such as the expression of genes involved in the visual cycle pathway, pigmentation and cell adhesion. Importantly miRNAs of the RPE were found to be required for maturation of the adjacent photoreceptors, specifically for the morphogenesis of the outer segments. The profiles of miRNA and mRNA altered in the Dicer1 deficient RPE point to a key role of miR-204 in regulation of RPE differentiation program in vivo and uncovers the importance of additional novel RPE miRNAs. The study exposes the combined regulatory activity of miRNAs of the RPE, which is required for RPE differentiation and for the development of the adjacent neuroretina. Effect of Dicer 1 deficiency on RPE miRNA and mRNA.
