title: Differentiation of cultured neuroblastoma induced by staurosporine and cyclic AMP: methods for assessing a neuronal phenotype.
abstract: In cultured neuronal cells, neurite outgrowth provides a prominent morphological marker for assessing neurotrophic activity derived from different sources. Permanent cell lines are often used for such studies; however, the process of differentiation should be evaluated biochemically or electrophysiologically to determine whether the affected cells acquire a neuronal phenotype. We have reported that low-dose staurosporine acts synergistically with cyclic AMP to induce neuronal differentiation in a human neuroblastoma cell line. This protocol describes a method for examining phenotypic changes in cultured cells.
