What is the Origin of Growth Factor Secretagogues?

The term secretagogue is derived from secrete and the Greek agogos (leading forth), meaning something that actively causes secretion of a substance. Growth factors are polypeptides mediating critical processes like cellular proliferation and differentiation. The term signifies an internal stimulation strategy targeting the endocrine system's release capability.

What is the Mechanism of Growth Factor Secretagogues?

Secretagogues typically work by modulating upstream regulators, most commonly by stimulating the pituitary gland to increase the release of Growth Hormone (GH) into systemic circulation. This subsequent GH surge then acts primarily on the liver and peripheral tissues to stimulate the local production and release of IGF-1. Certain nutritional inputs or targeted physiological stressors can also act as peripheral secretagogues, enhancing local tissue repair responses directly.

Growth Factor Secretagogues

Meaning

Growth Factor Secretagogues are defined as agents or stimuli designed specifically to promote the endogenous release of beneficial growth factors, such as Insulin-like Growth Factor 1 (IGF-1), from their natural production sites within the body. These compounds stimulate the body’s own internal mechanisms rather than supplying the factor exogenously. This approach is favored because it supports the natural integrity and responsiveness of the existing endocrine axis.
