Growth factors are cell-surface receptor-binding proteins that encourage the growth and development of target cells.
<h3>What is Growth Factor ?</h3>
A growth factor is a naturally occurring chemical that promotes cell proliferation, wound healing, and, on rare occasions, cellular differentiation. It is usually a secreted protein or a steroid hormone. Growth factors play a crucial role in the regulation of many cellular processes.
- A growth factor is a protein that stimulates the growth of specific tissues. Growth factors are found in a wide variety of animals, including insects, amphibians, humans, and plants, and they serve a crucial role in encouraging cellular differentiation and cell division.
- Growth factors are commonly used as a signaling molecule between cells. Cytokines and hormones, for example, attach to specific receptors on the surface of their target cells. As a result, the correct answer is proteins that bind to surface receptors and excite target cells.
Growth factors are local regulators that - bind to cell-surface receptors and stimulate growth and development of target cells.
