Dopamine Uptake in the Somatic Cell Hybrid NX31.

Abstract : The authors have investigated the kinetics and pharmacology of membrane transport of 3,4-dihydroxyphenylethylamine (dopamine) in the neuroblastoma clone N18TG2 and mouse sympathetic ganglion cells. NX31 was grown in exponential growth phase and in the presence of dibutyryl cyclic adenosine monophosphate, a compound known to initiate morphological and biochemical modulation, in order to investigate possible transitions in kinetic properties during differentiation.
