Neurobiology of Disease, 2009 In recent years, GDNF has emerged as a protective and restorative agent in several models of neurodegeneration; however, the exact molecular mechanisms responsible for these effects are not yet fully understood. Here we examined the effects of astrocytes

Morris Water Maze Learning in Two Rat Strains Increases the Expression of the Polysialylated Form of the Neural Cell Adhesion Molecule in the Dentate Gyrus But Has No Effect on Hippocampal Neurogenesis [PDF]
, 2005 In the current study, the authors investigated whether Morris water maze learning induces alterations in hippocampal neurogenesis or neural cell adhesion molecule (NCAM) polysialylation in the dentate gyrus.

Human Amniotic Fluid Cells Form Functional Gap Junctions with Cortical Cells
Stem Cells International, 2012 The usage of stem cells is a promising strategy for the repair of damaged tissue in the injured brain. Recently, amniotic fluid (AF) cells have received a lot of attention as an alternative source of stem cells for cell-based therapies.

Molecular mechanisms of neurogenic aging in the adult mouse subventricular zone [PDF]
, 2019 In the adult rodent brain, the continuous production of new neurons by neural stem/progenitor cells (NSPCs) residing in specialized neurogenic niches and their subsequent integration into pre-existing cerebral circuitries supports odour discrimination ...

Frontiers in Cellular Neuroscience, 2022 The adult neurogenic niches are complex multicellular systems, receiving regulatory input from a multitude of intracellular, juxtacrine, and paracrine signals and biological pathways. Within the niches, adult neural stem cells (aNSCs) generate astrocytic

Frontiers in Neuroscience, 2022 Postnatal and adult neurogenesis takes place in the dentate gyrus of the hippocampus in the vast majority of mammals due to the persistence of a population of neural stem cells (NSCs) that also generate astrocytes and more NSCs.

Essential role for PDGF signaling in ophthalmic trigeminal placode induction [PDF]
, 2008 Much of the peripheral nervous system of the head is derived from ectodermal thickenings, called placodes, that delaminate or invaginate to form cranial ganglia and sense organs.

Radial glia in the proliferative ventricular zone of the embryonic and adult turtle, Trachemys scripta elegans. [PDF]
, 2014 To better understand the role of radial glial (RG) cells in the evolution of the mammalian cerebral cortex, we investigated the role of RG cells in the dorsal cortex and dorsal ventricular ridge of the turtle, Trachemys scripta elegans.

Naked cuticle is essential for Drosophila wing development beyond Wingless signaling
FEBS Open Bio, EarlyView.Naked cuticle (Nkd), a Wnt signaling inhibitor, assumes extensive roles in Drosophila wing development. Overexpressing Nkd causes smaller, crumpled wings, while also perturbing multiple signaling pathways and developmental genes. A specific region (R1S) is critical for Nkd's function as a signaling integrator, offering new insights for studying its ...

Functional anterior pituitary generated in self-organizing culture of human embryonic stem cells
Nature Communications, 2016 It is difficult to generate functional human anterior pituitary tissues in vitro. Here, Ozone et al. generate human anterior pituitary from embryonic stem cells by recapitulating in vivodevelopment, and demonstrate this tissue secretes hormones and ...
