Abstract

Fibroblast growth factor (FGF), a polypeptide that has been shown to stimulate division in 3T3 cells, was tested for mitogenic effects on diploid, early-passage cells from human and murine sources. The quantitative assay of [3H]thymidine incorporation into acid-insoluble material showed that FGF at low concentrations (10 minus 9 M) was more effective than additional serum for provoking the initiation of DNA synthesis in human foreskin fibroblasts or mouse fibroblasts maintained in 5 or 10% serum, respectively. The growth of the human fibroblasts was twice as fast in the presence of FGF plus 10% calf serum as it was in the presence of 10% calf serum or 20% fetal calf serum alone. The addition of FGF to primary cultures of mouse fibroblasts in 0.4% serum resulted in a twofold increase in cell number compared to controls. In contrast to results obtained with 3T3 cells, neither insulin nor a glucocorticoid potentiated the effects of FGF on either human or mouse cells.

摘要

成纤维细胞生长因子(FGF)是一种已被证明能刺激3T3细胞分裂的多肽,对来自人和小鼠的二倍体、早期传代细胞的促有丝分裂作用进行了测试。将[3H]胸腺嘧啶核苷掺入酸不溶性物质的定量分析表明,低浓度(10的负9次方摩尔)的FGF比额外添加血清更有效地激发分别在5%或10%血清中培养的人包皮成纤维细胞或小鼠成纤维细胞中DNA合成的起始。在添加FGF加10%小牛血清的情况下,人成纤维细胞的生长速度是仅添加10%小牛血清或20%胎牛血清时的两倍。在0.4%血清中向小鼠成纤维细胞原代培养物中添加FGF,与对照组相比,细胞数量增加了两倍。与在3T3细胞中获得的结果相反,胰岛素和糖皮质激素均不能增强FGF对人或小鼠细胞的作用。
