Downregulation of ETS rescues diabetes-induced reduction of endothelial progenitor cells [PDF]

, 2009
Background Transplantation of vasculogenic progenitor cells (VPC) improves neovascularization after ischemia. However, patients with type 2 diabetes mellitus show a reduced VPC number and impaired functional activity. Previously, we demonstrated that p38

Stabilization of the retinal vascular network by reciprocal feedback between blood vessels and astrocytes [PDF]

, 2005
Development of the retinal vasculature is controlled by a hierarchy of interactions among retinal neurons, astrocytes and blood vessels. Retinal neurons release platelet-derived growth factor (PDGFA) to stimulate proliferation of astrocytes, which in ...

Molecular Characterization of Human Retinal Progenitor Cells

Investigative Opthalmology & Visual Science, 2009
To examine the molecular profile of fetal human retinal progenitor cells (hRPCs) expanded in vitro and those grown in a co-culture system with mouse retina through the analysis of protein and gene expression and neurotransmitter-stimulated calcium dynamics.hRPCS were isolated from human retina of 14 to 18 weeks gestational age (GA) and expanded in ...

Profound Re-Organization of Cell Surface Proteome in Equine Retinal Pigment Epithelial Cells in Response to In Vitro Culturing [PDF]

, 2012
The purpose of this study was to characterize the cell surface proteome of native compared to cultured equine retinal pigment epithelium (RPE) cells. The RPE plays an essential role in visual function and represents the outer blood-retinal barrier.

TULP4, a novel E3 ligase gene, participates in neuronal migration as a candidate in schizophrenia

CNS Neuroscience &Therapeutics, EarlyView., 2023
Mutations identified from four SCZ pedigrees resulted in decreased TULP4 expression. Tulp4 knockdown caused delayed neuron migration in embryonic mice, and impaired cognition and prepulse inhibition in adult mice. These phenotypes may be related to TULP4 through its involvement in the formation of a novel E3 ubiquitin ligases.

PlexinA2 and Sema6A are required for retinal progenitor cell migration [PDF]

Development, Growth & Differentiation, 2016
In the vertebrate retina six types of neurons and one glial cell type are generated from multipotent retinal progenitor cells (RPCs) whose proliferation and differentiation are regulated by intrinsic and extrinsic factors. RPCs proliferate undergoing interkinetic nuclear migration within the neuroblastic layer, with their nuclei moving up and down ...

Individual retinal progenitor cells display extensive heterogeneity of gene expression. [PDF]

PLoS ONE, 2008
The development of complex tissues requires that mitotic progenitor cells integrate information from the environment. The highly varied outcomes of such integration processes undoubtedly depend at least in part upon variations among the gene expression ...

Single-cell RNA sequencing unravels the transcriptional network underlying zebrafish retina regeneration

eLife, 2023
In the lesioned zebrafish retina, Müller glia produce multipotent retinal progenitors that generate all retinal neurons, replacing lost cell types. To study the molecular mechanisms linking Müller glia reactivity to progenitor production and neuronal ...

In Vitro Isolation and Expansion of Human Retinal Progenitor Cells [PDF]

Experimental Neurology, 2002
Human retinal development proceeds with temporal and spatial precision. Although differentiation starts around the beginning of the third month of gestation, the majority of cells in the outer neuroblastic layer of human neural retina are still proliferating, as evidenced by their Ki-67 immunoreactivity.
