whereas the combination of huifn-alpha ( 10 to 1000 iu/ml ) with dmso also did not affect the proliferation or differentiation of hl-60 cells , the addition of huifn-beta ( 1000 iu/ml ) and dmso ( 1.25 % ) to growing cultures reduced cell viability as much as 14 % of that observed for cells treated with dmso alone or to 4 % of that observed for either untreated cells or those treated with huifn-beta alone .
