Semaphorins are a large family of proteins that are classically associated with axon guidance. These proteins and their interacting partners, the neuropilins and plexins are now known to be key mediators in a variety of processes throughout the nervous system ranging from synaptic refinement to the correct positioning of neuronal and glial cell bodies. Recently, much attention has been given to the...
Cell surface markers of neuronal precursor cells are of interest since they allow the isolation of these cells from mixed populations of cells. The monoclonal antibody (mAb) 2F7, a cell surface marker, has been shown to label neuronal precursors and post-mitotic neurones in the embryonic rat spinal cord and cortex. Little is known about the expression of the epitope recognised by mAb 2F7 in other...
The neurosphere culture system is widely used to expand neural stem/progenitor cells in vitro and to provide a source of cells for transplantation approaches to CNS disorders. This study describes the populations of neurones, astrocytes and oligodendrocytes which differentiated from embryonic day (E) 14 rat cortical and striatal tissue grown as neurosphere cultures over three passages. The percentages...
