Known for their regenerative function and incredible therapeutic potential, growth factors (GFs) have proven to be critical for the stimulation of growth and proliferation in living cells. GFs are natural signaling molecules excreted by various cells, but particularly fibroblasts, the most common cells of connective tissue. Today, the topical application of growth factors has been acknowledged for its many benefits. Immunologist and inventor, Ahmed Al-Qahtani, Ph.D., studied growth factors while researching the stages of wound healing in third degree burn patients. He found the complexity and coordination of the cell signaling molecules have a direct effect on cell proliferation, migration, chemotaxis and angiogenesis in the healing phases. Their ability to easily penetrate bare skin and enhance the immune response triggers secretion of other vital growth factors necessary to repair the skin.
