Adult limbal neurosphere cells: a potential autologous cell resource for retinal cell generation

, 2014
The Corneal limbus is a readily accessible region at the front of the eye, separating the cornea and sclera. Neural colonies (neurospheres) can be generated from adult corneal limbus in vitro.

Hamartomas of the Retina and Optic Disc

Türk Oftalmoloji Dergisi, 2022
Hamartomas are local malformation of cells that demonstrate abnormal proliferation in the area where they are normally present. Retinal and optic disc hamartomas include astrocytic hamartoma, congenital hypertrophy of the retinal pigment epithelium ...

AMD-Like Substrate Causes Epithelial Mesenchymal Transition in iPSC-Derived Retinal Pigment Epithelial Cells Wild Type but Not C3-Knockout

, 2021
The Bruch’s membrane (BrM) is a five-layered extracellular matrix (ECM) that supports the retinal pigment epithelium (RPE). Normal age-related changes in the BrM may lead to RPE cell damage and ultimately to the onset and progression of age-related ...

Expression of R345W-Fibulin-3 Induces Epithelial-Mesenchymal Transition in Retinal Pigment Epithelial Cells

Frontiers in Cell and Developmental Biology, 2020
PurposeTo investigate the role of protein misfolding in retinal pigment epithelial (RPE) cell dysfunction, the effects of R345W-Fibulin-3 expression on RPE cell phenotype were studied.MethodsPrimary RPE cells were cultured to confluence on Transwells and

Annexin A2 promotes proliferative vitreoretinopathy in response to a macrophage inflammatory signal in mice

Nature Communications
Proliferative vitreoretinopathy is a vision-threatening response to penetrating ocular injury, for which there is no satisfactory treatment. In this disorder, retinal pigment epithelial cells, abandon their attachment to Bruch’s membrane on the scleral ...

Molecular Responses of Human Retinal Cells to Infection with Dengue Virus

Mediators of Inflammation, 2017
Recent clinical reports indicate that infection with dengue virus (DENV) commonly has ocular manifestations. The most serious threat to vision is dengue retinopathy, including retinal vasculopathy and macular edema.

Molecular Basis of The Retinal Pigment Epithelial Changes That Characterize The Ocular Lesion in Toxoplasmosis

Microorganisms, 2019
When a person becomes infected with Toxoplasma gondii, ocular toxoplasmosis is the most common clinical presentation. The medical literature describes retinitis with surrounding hyperpigmentation secondary to proliferative changes in the retinal pigment ...

Induced retinal pigment epithelial cells with anti-epithelial-to-mesenchymal transition ability delay retinal degeneration

iScience, 2022
Summary: The hostile microenvironment of the retina in patients with age-related macular degeneration (AMD) may trigger epithelial-to-mesenchymal transition (EMT) of grafted retinal pigment epithelial (RPE) cells, thus attenuating the therapeutic outcome.

Quantified F-Actin Morphology Is Predictive of Phagocytic Capacity of Stem Cell-Derived Retinal Pigment Epithelium

Stem Cell Reports, 2018
Summary: With stem cell-derived retinal pigment epithelial (RPE) replacement therapies in clinical testing, establishing potency of RPE prior to transplantation is imperative. Phagocytosis of photoreceptor outer segment fragments (POS) is a key indicator
