Abstract
During brain development, the embryonic cerebrospinal fluid (E-CSF) allows brain expansion and promotes neuroepithelial cell survival, proliferation or differentiation. Previous analyses of E-CSF content have revealed a high protein concentration and the presence of membranous particles. The role of these particles in the E-CSF remains poorly investigated. In this study we showed that the E-CSF contains at least two pools of particles: lipoproteins and exosome-like particles. We showed that these two populations of particles strongly interact with neuropithelial cells via an endocytic process, which display regional specificity along the developing neural tube. Finally, we explore and discuss the possibility that these interactions may influence brain development through the regulation of morphogen and growth factor signaling transduction.
