hippocampal neural stem/progenitor cells (hipp-ns/pcs) of the adult mammalian brain are important sources of neuronal and gial cell production. in this study, the main goal is to investigate the plasticity of these cells in neuronal/astroglial differentiations. to this end, the differentiation of the hipp-ns/pcs isolated from 3-month-old wistar rats was investigated in response to the embryonic...

objective: embryonic cerebrospinal fluid (e-csf) has an important role in development of embryonic and adult brain. proteomic analysis suggests that this fluid has many morphogenes and cytokines that alter in time and space throughout embryonic life. the aim of this study was to evaluate the developmental effect of embryonic csf on proliferation and differentiation of neuroprogenitor cells in d...

Matrix metalloproteinases (MMPs) foster cellular invasion by disrupting extracellular matrix barriers and thereby facilitate tumor development. MMPs are synthesized by both cancer cells and adjacent stromal cells, primarily macrophages. The production of macrophages is regulated by colony-stimulating factor-1 (CSF-1). Tissue CSF-1 expression increased significantly in embryonic and colon cancer...

In vertebrates, early brain development takes place at the expanded anterior end of the neural tube, which is filled with embryonic cerebrospinal fluid (E-CSF). We have recently identified a transient blood–CSF barrier that forms between embryonic days E3 and E4 in chick embryos and that is responsible for the transport of proteins and control of E-CSF homeostasis, including osmolarity. Here we...

In vertebrates, early brain development takes place at the expanded anterior end of the neural tube. After closure of the anterior neuropore, the brain wall forms a physiologically sealed cavity that encloses embryonic cerebrospinal fluid (E-CSF), a complex and protein-rich fluid that is initially composed of trapped amniotic fluid. E-CSF has several crucial roles in brain anlagen development. ...

The CSF is a complex fluid with a dynamically varying proteome throughout development and in adulthood. During embryonic development, the nascent CSF differentiates from the amniotic fluid upon closure of the anterior neural tube. CSF volume then increases over subsequent days as the neuroepithelial progenitor cells lining the ventricles and the choroid plexus generate CSF. The embryonic CSF co...

The brain ventricular system is composed of a highly conserved set of cavities that contain cerebrospinal fluid (CSF), a protein-rich fluid essential for brain function. However, little is known about the function of embryonic CSF (eCSF), or the mechanisms of CSF production, retention, and circulation that regulate brain ventricle shape and size. Here we present data that begins to dissect the ...

OBJECTIVE Embryonic cerebrospinal fluid (e-CSF) has an important role in development of embryonic and adult brain. Proteomic analysis suggests that this fluid has many morphogenes and cytokines that alter in time and space throughout embryonic life. The aim of this study was to evaluate the developmental effect of embryonic CSF on proliferation and differentiation of neuroprogenitor cells in di...

Cerebrospinal fluid (CSF) includes conserved factors whose function is largely unexplored. To assess the role of CSF during embryonic development, CSF was repeatedly drained from embryonic zebrafish brain ventricles soon after their inflation. Removal of CSF increased cell death in the diencephalon, indicating a survival function. Factors within the CSF are required for neuroepithelial cell sur...
