Conditional activation of Bmi1 in embryonic and postnatal neural stem/progenitor cells in mouse models: analysis of its effect on their biological properties and tumourigenesis [PDF]

open access: yes, 2011
PhDThe Polycomb group protein Bmi1 is a key transcriptional regulator of self renewal of embryonic and adult neural stem and progenitor cells (NSPC) and its over-expression has been shown to occur in several types of brain tumour.

Early evolution of radial glial cells in Bilateria [PDF]

open access: yes, 2017
Bilaterians usually possess a central nervous system, composed of neurons and supportive cells called glial cells. Whereas neuronal cells are highly comparable in all these animals, glial cells apparently differ, and in deuterostomes, radial glial cells ...

Cellular and Molecular Mechanisms regulating Cell Proliferation during the Forebrain Development of the Mouse [PDF]

open access: yes, 2005
The predominant precursor cell type during cortical neurogenesis are radial glia cells, which receive extrinsic and intrinsic signals that might influence cell proliferation and neurogenesis.

2116 Exploring Müller cell-cone interactions in human fovea using 3-dimensional volume electron microscopy (EM)

open access: yesJournal of Clinical and Translational Science, 2018
OBJECTIVES/SPECIFIC AIMS: Müller cells, radial glial cells of the retina, are the principal repository of xanthophyll pigment (lutein, zeaxanthin, meso-zeaxanthin), which are modifiable by diet and visible clinically by autofluorescence imaging.

Niche-independent symmetrical self-renewal of a mammalian tissue stem cell. [PDF]

open access: yes, 2005
Pluripotent mouse embryonic stem (ES) cells multiply in simple monoculture by symmetrical divisions. In vivo, however, stem cells are generally thought to depend on specialised cellular microenvironments and to undergo predominantly asymmetric divisions.

Neurogliogenesis and visual system development in "Drosophila" : genetic/genomic analysis of the "Glial cells missing" and "Egghead" genes [PDF]

open access: yes, 2005
Complex nervous systems are made up by two major cell types, neuronal and glial cell types. A general observation that has been made by lineage analysis of neurogliogenesis in vertebrates and invertebrates is that neurons and glia often share common ...

Ion activities and potassium uptake mechanisms of glial cells in guinea-pig olfactory cortex slices. [PDF]

open access: yes, 1987
1. Double-barrelled ion-sensitive micro-electrodes were used to measure changes in the intracellular activities of K+, Na+ and Cl- (aiK, aiNa, aiCl) in glial cells of slices from guinea-pig olfactory cortex during repetitive stimulation of the lateral ...

Tight junction protein occludin regulates progenitor Self-Renewal and survival in developing cortex

open access: yeseLife, 2019
Occludin (OCLN) mutations cause human microcephaly and cortical malformation. A tight junction component thought absent in neuroepithelium after neural tube closure, OCLN isoform-specific expression extends into corticogenesis.

Mouse embryonic stem cells as a discovery tool in neurobiology [PDF]

open access: yes, 2012
Mouse ES cells can recapitulate, under suitable tissue culture conditions, early events in neurogenesis. As wildtype or genetically modified ES cells can be grown in unlimited quantities, their differentiation into neurons represents an attractive model

Radial glial cells defined and major intermediates between embryonic stem cells and CNS neurons

open access: yes, 2005
Radial glial cells have been identified as a major source of neurons during development. Here, we review the evidence for the distinct "glial" nature of radial glial cells and contrast these cells with their progenitors, the neuroepithelial cells. Recent
