cells preincubated with microfilament modifiers , cytochalasin a , b , and d ( 10 mug/ml ) , had decreased binding of insulin ( 30 % ) and human growth hormone ( 60 % ) under steady state conditions , which was not reversed by removing the cytochalasins from the medium and was due entirely to a reduced number of receptor sites on the cell surfact .
