in accord with the idea that modulation of membrane processes such as na+/k+ pump activity in fibroblasts may reflect important events related to the initiation of dna synthesis , it was observed that in both 3t3-4 and c3h-10t1/2 cells there were parallel increases in 3h-tdr incorporation and ouabain-sensitive 86rb+ influxes with 10 ( -7 ) m tpa , whereas pgf2 alpha stimulated a significant increase in 3h-tdr incorporation in 3t3-4 but not c3h-10t1/2 cells and only marginal increases in ouabain-sensitive 86rb+ influx in both .
