Theses, Dissertations and Capstones
Silver nanoparticles (AgNP) are an emerging environmental contaminant with unique chemical and physical properties. They are utilized in products like medical dressings and children’s toys for their antimicrobial action. Though AgNP’s bioaccumulative nature and high-level toxicity are established, low-level effects from chronic exposure to AgNP-containing products and environmental AgNP remain unclear. This study uses adult neural stem cells, a model for neural cell function and neurodevelopment, to assess changes in cell differentiation and behavior following low-level AgNP exposure. In vitro, low-level AgNP produced dose- and timedependent formation of co-localized f-actin inclusions and β-catenin puncta. Neurite extension and arborization were also …
