✦ Synopsis

Neural stem cells are maintained in second most common cell type in this germinal layer. the subventricular zone (SVZ) of the adult mamma-The most actively proliferating cells in the SVZ, type lian brain. Here, we review the cellular organization C, form small clusters dispersed throughout the netof this germinal layer and propose lineage relationwork. These foci of proliferating type C cells are in ships of the three main cell types found in this area. close proximity to chains of type A cells. We discuss The majority of cells in the adult SVZ are migrating possible lineage relationships among these cells and neuroblasts (type A cells) that continue to proliferate. hypothesize which are the neural stem cells in the These cells form an extensive network of tangentially adult SVZ. In addition, we suggest that interactions oriented pathways throughout the lateral wall of the between type A, B, and C cells may regulate proliferalateral ventricle. Type A cells move long distances tion and initial differentiation within this germinal through this network at high speeds by means of chain layer.
