Abstract
This paper is based on the thesis Growth Factors and Formation of Granulation Tissue, University of Göteborg, 1992. For the last decade, it has been acknowledged that growth factors are essential for regulating the cellular events involved in the formation of granulation tissue and in wound healing. Recently, clinical trials were initiated to study the wound healing effect of applying growth factors and growth hormone to human wounds. However, in order to apply growth factors in these trials in an intelligent and effective manner, it is important to understand their physiology and their role in wound healing. This review paper is about the growth factors: IGF-I, IGF-II, PDGF, bFGF, TGF-beta, EGF, TGF-alpha, TNF-alpha, SF-HGF and Growth Hormone and their role and effect in soft tissue wound healing in animals and humans.
