Fetal Brain Injury Models of Fetal Alcohol Syndrome: Examination of Neuronal Morphologic Condition Using Sholl Assay.

The lack of a convenient in vitro human neuronal model to study alcohol-induced neurodegenerative diseases, such as fetal alcohol syndrome (FAS), prompted us to develop human neuronal culture and in vitro human FAS model by incubating cells with physiologically relevant EtOH concentration (50 mM). Here, we describe the detailed method of isolation of human neuronal culture, and ability to analyze neurites extension using Sholl assay. We utilized highly efficient transfection method of neuronal cells to study morphology of neurons with or without EtOH treatment.
