Abstract
Wound healing is a dynamic process that involves the integrated action of a number of cell types, the extra cellular matrix, and soluble mediators termed cytokines. In recent years considerable advances have been made in the research, knowledge, and understanding of growth factors. Growth factors are, in essence, proteins that communicate activities to cells. Their function is dependent on the receptor site they attach to. Growth factors were initially named for the type of response generated by them, but newer research has shown that many of these cells may accomplish many different types of response. A growth factor's role in wound repair is a critical component of the successful resolution of a wound. Growth factors help regulate many of the activities involved in healing. The role and function of growth factor is an evolving area of science and offers the potential for treatment alternatives in the future.
