two separate mechanisms of modulation of ectopic hcg by these cells are possible : a camp-mediated stimulation independent of cell-growth kinetics after exposure to dibutyryl camp and prostaglandin f1 alpha , and a selective inhibition of dna synthesis which results in slowing of cell replication and concomitant increase in hcg production per cell .
