GROWTH FACTORS PERFORM THEIR FUNCTIONS IN LIQUIDS AND TISSUES


Growth factors are a type of substance that performs an important function in intercellular communication. They also perform many other biological functions, the most important of which is cell proliferation, although they still directly affect cell survival, migration, differentiation, and even apoptosis.
Growth factors perform their functions in liquids and tissues in very low concentrations, within picograms or nanograms. They act by attaching to receptors located on the cell membrane and transmit a signal from outside to inside the cell, through compounds with various phosphorylated protein kinases that regulate the signaling cascade, resulting in the activation of one or more genes.
Growth factors are a type of substance that is essential in communication between cells.
