title: [The character of heredity and biological function of insulin-like growth factor 2].
abstract: Insulin-like growth factor (IGF) is multiple proliferation controlling factor of cells, and it gets this name according to its similarity to insulin. IGF2 is a single chain protein of 67 amino acids, which is probably required for normal fetal growth and development. In this article, we discussed the gene structure, ways of its heredity, and biological effects concerning imprinting, tumor development,muscle forming and individual growing of IGF2.
