纤维细胞生长因子(FGF)是分子量为16000—18000的蛋白,对中胚层来源的细胞,如成纤维细胞,血管内皮细胞有促进增殖作用。正常机体,除脑组织外,其他器官组织中FGF含量极低,不易检出。在慢性纤维化疾病和脑损伤时,FGF明显增加。油酸可引起多种动物急性肺损伤,导致反应性细胞增生,肺纤维 Fibroblast growth factor (FGF) is a protein with a molecular weight of 16000-18000, which can promote the proliferation of mesoderm-derived cells such as fibroblasts and vascular endothelial cells. Normal body, in addition to brain tissue, other organ tissue FGF content is very low, not easy to detect. In chronic fibrotic diseases and brain damage, FGF increased significantly. Oleic acid can cause acute lung injury in a variety of animals, leading to reactive cell proliferation, pulmonary fibrosis
