The biology of adult brain neural stem cells
My research focuses on neural stem cell-driven cytogenesis in the adult brain and more specifically on the activity of the subependymal zone neurogenic/gliogenic niche. I have investigated the structural features of the niche (extracellular matrix, ependymal cells and the cerebrospinal fluid, blood vessels) in respect to the regulation of adult neural stem cell behaviour. How is the niche microenvironment altered when stem cells become activated in order to regenerate the neural tissue? How has the structure of the niche changed during evolution? Recently I have started exploring more intensively the oligodendrogenic properties of the subependymal zone, especially in the context of the ageing brain and of demyelinating diseases, as well as the potential to develop new methods to isolate neural progenitors from the niche.
