Intravitreal Injection of Human Retinal Progenitor Cells for Treatment of Retinal Degeneration [PDF]

open access: yesMedical Science Monitor, 2020
BACKGROUND Retinal degeneration causes irreversible blindness. Human retinal progenitor cells (hRPCs) have the potential to treat retinal diseases. The vitreous cavity is a relatively immune-privileged site that is suitable for stem cell transplantation in the treatment of retinal diseases.

Expression of SIRT1 and DBC1 in Developing and Adult Retinas

open access: yesStem Cells International, 2012
Sirtuin 1 (SIRT1) is a deacetylase that can regulate various biological processes via repression of transcription. Its activity has been linked to the differentiation of neural progenitor cells, although little is known about its function during retinal ...

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

open access: yesPLoS ONE, 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.

Clues from Crouzon: Insights into the potential role of growth factors in the pathogenesis of myelinated retinal nerve fibers. [PDF]

open access: yes, 2016
PurposeWe present a case of bilateral extensive peripapillary myelinated retinal nerve fibers (MRNF) in an individual with Crouzon syndrome, an inherited form of craniosynostosis caused by overactivation of fibroblast growth factor receptor 2.

Progress of stem/progenitor cell-based therapy for retinal degeneration

open access: yesJournal of Translational Medicine, 2017
Retinal degeneration (RD), such as age-related macular degeneration (AMD) and retinitis pigmentosa, is one of the leading causes of blindness. Presently, no satisfactory therapeutic options are available for these diseases principally because the retina ...

Notch pathway mutants do not equivalently perturb mouse embryonic retinal development.

open access: yesPLoS Genetics, 2023
In the vertebrate eye, Notch ligands, receptors, and ternary complex components determine the destiny of retinal progenitor cells in part by regulating Hes effector gene activity. There are multiple paralogues for nearly every node in this pathway, which

The ratio of VEGF/PEDF expression in bone marrow mesenchymal stem cells regulates neovascularization [PDF]

open access: yes, 2011
Angiogenesis, or neovascularization, is a finely balanced process controlled by pro- and anti-angiogenic factors. Vascular endothelial growth factor (VEGF) is a major pro-angiogenic factor, whereas pigment epithelial-derived factor (PEDF) is the most ...

Cell Fate of Retinal Progenitor Cells: In Ovo UbC-StarTrack Analysis

open access: yesInternational Journal of Molecular Sciences, 2022
Clonal cell analysis outlines the ontogenic potential of single progenitor cells, allowing the elucidation of the neural heterogeneity among different cell types and their lineages. In this work, we analyze the potency of retinal stem/progenitor cells through development using the chick embryo as a model.

The Retinal Pigment Epithelium Is a Notch Signaling Niche in the Mouse Retina

open access: yesCell Reports, 2017
Summary: Notch signaling in neural progenitor cell is triggered by ligands expressed in adjacent cells. To identify the sources of active Notch ligands in the mouse retina, we negatively regulated Notch ligand activity in various neighbors of retinal ...

Glucocorticoid agonists enhance retinal stem cell self-renewal and proliferation

open access: yesStem Cell Research & Therapy, 2021
Background Adult mammalian retinal stem cells (RSCs) readily proliferate, self-renew, and generate progeny that differentiate into all retinal cell types in vitro.
