The overall goal of this procedure is to deliver low volumes of high titer lentiviral particles carrying specific DNA constructs to the adult mouse ventricular-subventricular zone to infect all of its cell types or to the lateral ventricle to affect ependymal cells only.This method can help answer key questions about interactions that neural stem cells of the adult ventricular-subventricular niche have with their neighboring ependymal cells.The main advantage of this technique is that lentiviral vectors integrate into the genome of target cells in a cell cycle independent way, allowing for long-term diffication of rarely dividing cells.Helping me to demonstrate the procedure will be grad student Beatriz Mart
