What is a Growth Factor? Mechanism of Action of Growth Factor
A growth factor is a protein molecule that is released by cells and signals neighboring cells to divide and grow. The mechanism of action of growth factor is by binding to a receptor on the surface of the target cell, which initiates a signal transduction pathway that leads to cell proliferation.
Growth Factor and Control of Cell Growth.
Growth factors are proteins that control the growth of cells. They are produced by cells and bind to receptors on the surface of other cells. This interaction stimulates the cells to grow, divide, or differentiate.
The Antagonist of Growth Factor
The antagonist of growth factor is a protein that binds to and inhibits the action of growth factors. This protein can block the growth of new blood vessels, which can inhibit the growth of tumors. It can also block the growth of new cells in other tissues, which can lead to tissue damage.
Types of Growth Factors
There are three main types of growth factors:
1. Epidermal growth factor (EGF)
2. Fibroblast growth factor (FGF)
3. Platelet-derived growth factor (PDGF)
