we conclude that 1 ) the immunoassayable egf in blood plasma and smg-egf do not appear to be major sources of u-egf but plasma egf may be a minor source , 2 ) kidney tissue appears not to be a major source of u-egf , 3 ) production of u-egf is activated by smg excision , 4 ) t4 increases both u- and k-egf while testosterone has no effect .
