earlier studies indicated that staging of cells in g1 by serum deprivation in the presence of phorbol esters such as phorbol 12-myristate 13-acetate ( pma ) induced a state ( s ) in which postconfluent c3h 10t1/2 fibroblasts were refractory to ouabain inhibition of dna synthesis , and the present study further examines this property .
