WebMay 30, 2012 · The balance between these processes regulates neural progenitors' proliferation and brain size. To explore a possible role for FlnA in cell fate specification, we first quantified the number of neural cells expressing several layer-specific markers relative to the number of Sox2+ progenitor cells in E15 and E18 FlnA y /− and FlnA y /+ cortices. WebDec 23, 2016 · Introduction. Microtubules fulfil a wide variety of critical functions throughout the development of the mammalian brain (1, 2): they form the mitotic spindle, provide a framework during cellular migration and process extension and provide a stable platform for intracellular transport.Defects in these processes can result in various neurological …
