title: Neuroblastoma X glioma NG108-15 hybrid cells cultured in a serum-free chemically defined medium: effects on acute and chronic opiate regulation of adenylate cyclase activity.
abstract: Neuroblastoma X glioma NG108-15 hybrid cells cultured in a chemically defined medium within 3 cell passages, exhibited viability, growth rate and morphology similar to those of cells grown in medium supplemented with 5% fetal calf serum. Hybrid cells cultured in the chemically defined medium within these periods of time also did not exhibit a difference in basal adenylate cyclase activity nor in the enzymatic activities stimulated by adenosine, forskolin, NaF, GppNHp or Mn2+. Furthermore, opiate receptor density in chemically defined medium cultured cells remained identical to that in cells cultured in 5% fetal calf serum. The acute and chronic effects of opiates on adenylate cyclase were similar for cells grown under either set of conditions.
