Growth factors are powerful agents that are capable of stimulating cellular migration, cellular growth, cellular duplication, and cellular differentiation. They can act on target tissues and regulate a variety of cellular events. Modulation of growth factors at the injury site of a damaged tissue is one of the strategies used to stimulate tissue regeneration. Growth factors can be found in the human umbilical cord and amniotic membrane. Thousands of growth factors are contained in BioIntegrate products and they help signal local cells to help heal the damaged tissue.
