期刊介绍：

BioFactors is an international journal aimed at identifying and increasing our understanding of the precise biochemical effects and roles of the large number of trace substances that are required by living organisms. These include vitamins and trace elements, as well as growth factors and regulatory substances made by cells themselves. The elucidation, in a particular organism or cell line, of the roles of substances active in trace quantities, is frequently applicable directly to many other forms of life.
