Id4 regulates neural progenitor proliferation and differentiation in vivo.
The mechanisms that determine whether a precursor cell re-enters the cell cycle or exits and differentiates are crucial in determining the types and numbers of cells that constitute a particular organ. Here, we report that Id4 is required for normal brain size, and regulates lateral expansion of the proliferative zone in the developing cortex and hippocampus. In its absence, proliferation of st...
متن کاملNFIX regulates neural progenitor cell differentiation during hippocampal morphogenesis.
Neural progenitor cells have the ability to give rise to neurons and glia in the embryonic, postnatal and adult brain. During development, the program regulating whether these cells divide and self-renew or exit the cell cycle and differentiate is tightly controlled, and imbalances to the normal trajectory of this process can lead to severe functional consequences. However, our understanding of...
متن کاملmiR-34a Regulates Mouse Neural Stem Cell Differentiation
BACKGROUND MicroRNAs (miRNAs or miRs) participate in the regulation of several biological processes, including cell differentiation. Recently, miR-34a has been implicated in the differentiation of monocyte-derived dendritic cells, human erythroleukemia cells, and mouse embryonic stem cells. In addition, members of the miR-34 family have been identified as direct p53 targets. However, the functi...
متن کاملConnexin 36 Expression Regulates Neuronal Differentiation from Neural Progenitor Cells
BACKGROUND Gap junction communication has been shown in glial and neuronal cells and it is thought they mediate inter- and intra-cellular communication. Connexin 36 (Cx36) is expressed extensively in the developing brain, with levels peaking at P14 after which its levels fall and its expression becomes entirely neuronal. These and other data have led to the hypothesis that Cx36 may direct neuro...
متن کاملFGF-4 regulates neural progenitor cell proliferation and neuronal differentiation.
The FGF-4 (fibroblast growth factor 4, known as HST-1) protein is an important mitogen for a variety of cell types. However, only limited information is available concerning tissue distribution and the biological role of FGF-4 in the brain. In situ hybridization analysis revealed localization of mouse Fgf-4 mRNA in the normal postnatal mouse hippocampus, subventricular zone (SVZ), and the rostr...
