in cultures seeded at low ( 1 x 10 ( 5 ) ) , medium ( 5 x 10 ( 5 ) ) , or high ( 2 x 10 ( 6 ) ) cell densities in a 25 cm2 flask , inhibition of cell proliferation and polyamine depletion by both r , r-map and dfmo was more pronounced at the lower densities relative to the density-matched control cells .
