abstract：:We have previously reported that Insulin-like growth factor (IGF-I) is a cellular growth factor of human transformed T-lymphocytes. To evaluate the role of IGF-I for nontransformed T-cells we investigated synthesis of IGF-I and the influence of an IGF-I antiserum, UBK487, during proliferation process. IGF-I is synthes...
