Evidence is presented to show the presence in normal rat serum of four different serum factors essential for growth of 3T3 or SV40-transformed 3T3 mouse fibroblasts: a factor that specifically promotes growth of normal 3T3 cells; two factors that specifically promote growth of transformed 3T3 cells; and a factor that sustains viability of both normal and transformed 3T3 cells in serum-free medium, probably without inducing growth of the cells. These factors are separated and partially purified.
有证据表明,正常大鼠血清中存在四种对3T3或SV40转化的3T3小鼠成纤维细胞生长至关重要的不同血清因子:一种特异性促进正常3T3细胞生长的因子;两种特异性促进转化的3T3细胞生长的因子;以及一种在无血清培养基中维持正常和转化的3T3细胞活力的因子,可能不会诱导细胞生长。这些因子被分离并部分纯化。
