we have recently shown that both lipopolysaccharide ( lps ) and the phorbol ester , 12-o-tetradecanoyl phorbol 13-acetate ( tpa ) induce differentiation in the transformed murine pre-b lymphocyte cell line 70z/3 by enhancing na+-h+ exchange across the plasma membrane through an amiloride-sensitive transport system ( rosoff , p.m. , stein , l.f. , and cantley , l.c .
