Hippocampal Mossy Cells Provide a Fate Switch for Adult Neural Stem Cells
(Cell Press, 2018-08)
The pathways that convert neural stem cells (NSCs) into functional neurons in the adult hippocampus are tightly regulated. In this issue of Neuron, Yeh et al. (2018) demonstrate that the activity of dentate mossy cells ...
Bifunctional Hydrogels Containing the Laminin Motif IKVAV Promote Neurogenesis
(Cell Press, 2017-11)
Engineering of biomaterials with specific biological properties has gained momentum as a means to control stem cell behavior. Here, we address the effect of bifunctionalized hydrogels comprising polylysine (PL) and a 19-mer ...
Conductive hydrogels based on agarose/alginate/chitosan for neural disorder therapy
(Elsevier, 2019-11)
Electroactive scaffolds derived from carbohydrate hydrogels were synthesized, resulting in a large shift in the conductivity of chitosan (CS) from 10−6 S/cm to about 10-3 S/cm, assigned to CS-oligoaniline. Several analyses ...
Insights into Stem Cell Factor chemotactic guidance of neural crest cells revealed by a real-time directionality-based assay
(Elsevier Gmbh, 2012-05)
The extracellular environment through which neural crest cells (NCCs) translocate and differentiate plays a crucial role in the determination of cell migration and homing. In the trunk, NCC-derived melanocyte precursor ...
Activation of Hes1 and Msx1 in transgenic mouse embryonic stem cells increases differentiation into neural crest derivatives
(MDPI, 2018-12)
The neural crest (NC) comprises an ectodermal multipotent cell population that produces peripheral neurons, cartilage and smooth muscle cells, among other phenotypes. The participation of Hes1 and Msx1 when expressed in ...
Molecular characterization of wdr68 gene in embryonic development of Xenopus laevis
(Elsevier Science, 2018-08)
WDR68, also known as DCAF7, is a WD40 repeated domain protein highly conserved in eukaryotic organisms in both plants and animals. This protein participates in numerous cellular processes and exerts its function through ...
Neurocristopathies: New insights 150 years after the neural crest discovery
(Academic Press Inc Elsevier Science, 2018-05)
The neural crest (NC) is a transient, multipotent and migratory cell population that generates an astonishingly diverse array of cell types during vertebrate development. These cells, which originate from the ectoderm in ...
TGFβ-signaling and FOXG1-expression are a hallmark of astrocyte lineage diversity in the murine ventral and dorsal forebrain
(Frontiers Research Foundation, 2018-11)
Heterogeneous astrocyte populations are defined by diversity in cellular environment, progenitor identity or function. Yet, little is known about the extent of the heterogeneity and how this diversity is acquired during ...
Kat6b Modulates Oct4 and Nanog Binding to Chromatin in Embryonic Stem Cells and Is Required for Efficient Neural Differentiation
(Academic Press Ltd - Elsevier Science Ltd, 2019-03)
Chromatin remodeling is fundamental for the dynamical changes in transcriptional programs that occur during development and stem cell differentiation. The histone acetyltransferase Kat6b is relevant for neurogenesis in ...
