Abstract

Cloned neuroblastoma cell lines derived from the spontaneous mouse tumor C-1300 were used to study nerve cell differentiation. Our findings included a) morphologic and electrical differentiation was induced by the addition of dimethyl sulfoxide to the culture medium of some of the neuroblastoma clonal lines; b) a contrasting difference existed between the percentage of the phenylalanine-specific, tRNA species deficient in the peroxy Y-nucleoside in the mouse embryo or rat brain (6-10%) and that of mouse neuroblastoma cells (85%); c) the assembly of neuroblastoma microtubules and neurofilaments that are necessary for neurite outgrowth proceeded from preexisting pools of tubulin and actin, but a sustained level of phosphorylated tubulin was not required for this regulation; and d) the in vitro translation of tubulin and actin was accomplished with mRNA from rat brains in a wheat-germ cellfree system.
