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

Cell 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 ...

The association between neural crest‐derived glia and melanocyte lineages throughout development and disease

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common

Preclinical Evaluation of a Cell-Based Gene Therapy Using the Sleeping Beauty Transposon System in Choroidal Neovascularization

Molecular Therapy: Methods & Clinical Development, 2019
Age-related macular degeneration (AMD) is a progressive retinal disorder characterized by imbalanced pro- and antiangiogenic signals. The aim of this study was to evaluate the effect of ex vivo cell-based gene therapy with stable expression of human ...

Role of SoxE transcription factors in development and disease

Developmental Dynamics, EarlyView.
Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

Zebrafish inversin mutants develop scoliosis in the absence of laterality defects

Developmental Dynamics, EarlyView.
Abstract Background Human mutations in INVERSIN are associated with nephronophthisis, variable penetrance of situs inversus and congenital heart disease. Inversin has been shown to localize to cilia and many of the patient phenotypes are attributed to disrupted cilia function.

Zebrafish ventral gastrula fate map reveals neural crest progenitor domain

Developmental Dynamics, EarlyView.
Abstract Background Fate maps relate progenitor cell positions to later fates and locations of their progeny, revealing early embryonic organization. Previous zebrafish fate maps identified the origin of germ layers and derivative cell fates, but ventral gastrula progenitor domains were not fully resolved. In particular, the neural crest, a multipotent

A Review of Artificial Intelligence in Ophthalmology: Key Aspects, Challenges, and Future Directions

Eye &ENT Research, EarlyView.
ABSTRACT Artificial intelligence (AI) is increasingly reshaping ophthalmology because the specialty depends heavily on structured imaging, quantitative measurements, and repeatable diagnostic workflows. This review provides a clinically grounded and translationally oriented synthesis of AI in ophthalmology, covering methodological foundations ...

Epinephrine, but not dexamethasone, induces apoptosis in human retinal pigment epithelium cells in vitro: Possible implications on the pathogenesis of central serous chorioretinopathy

Philippine Journal of Ophthalmology, 2004
Objective: The pathogenesis of central serous chorioretinopathy is poorly understood. It is believed to be due to dysfunction of the retinal pigment epithelium and/or choroid, and has been associated with elevated levels of epinephrine and administration
