生长因子(growth factor)这一研究领域进展极其迅速,近年来,证实了有些生长因子如PDGF、EGF与癌基因表达产物具有高度同源性,这一重大成果导致肿瘤的防治研究进入了分早水平。生长因子的研究无论从其进展速度或其本身具有的重要研究价值都足以引起人们极大的关注。其中PDGF、EGF、FGF及TGF等已有专题论述,本文仅将其他几种主要因子做一简要介绍。 The research field of growth factor has progressed extremely rapidly. In recent years, it has been confirmed that some growth factors such as PDGF and EGF have high homology with the expression products of oncogenes. This major achievement has led to the early research on the prevention and treatment of tumors Level. The research of growth factors is enough to arouse people’s attention in terms of its speed of progress or its important research value. PDGF, EGF, FGF and TGF have been discussed in detail. This article only briefly introduces several other major factors.
