Growth Factor is a protein molecule made by the body; it functions to regulate cell division & cell survival. Growth factors can also be produced by genetic engineering in the laboratory and used in biological therapy.
Growth factors are proteins that function as growth stimulators (mitogens) and/or growth inhibitors, stimulate cell migration, act as chemotactic agents, inhibit cell migration, inhibit invasion of tumor cells, modulate differentiated functions of cells, involved in apoptosis, involved in angiogenesis and promote survival of cells without influencing growth and differentiation.
