The differentiation of clonal rat yolk sac tumor cell lines cultivated with dibutyryl-cyclic 3', 5'-adenosine monophosphate.

Five rat yolk sac tumor cell lines were cloned from a yolk sac tumor line which originally arose following fetectomy. The doubling time of each of the cloned tumor lines was about 50 h. All of the cloned tumor cell lines synthesized and secreted AFP and albumin but there was a gradual decrease in the synthesis of these proteins during serial passage. The cells formed clusters which looked like vitelline ducts or the parietal yolk sac and they also had basement membranes which closely resembled Reichert's membrane. When the cloned cell lines were cultivated in the presence of 1 mM dibutyryl cyclic-AMP, myotube-like and neuron-like cells appeared. Acetylcholine esterase and creatine phosphokinase activity were present when myotube-like cells were present whereas acetylcholine esterase activity predominated when neuron-like cells were present.[1]
