Human FGF Analyte Overview

Human FGF

Also known as Human Basic Fibroblast Growth Factor, bFGF, FGF2, FGF-β

Basic Fibroblast Growth Factor (FGF-β, FGF-2) is a growth factor involved in the early development and maintenance of populations of embryonic and adult stem cells. During embryonic development it is critical for the pluripotency and self-renewal of embryonic stem cells, functioning to promote stem cell division and limit cellular differentiation. In adults is found in the basement membranes and extracellular matrix of blood vessels in many tissues, including neural, pituitary, adrenal cortex, corpus luteum, and placental tissues where it modulates wound healing, tissue repair, and neuronal function or degeneration. It has been demonstrated to be protective to heart tissue during a heart attack. Low levels of FGF-β are associated with anxiety disorders. FGF-β is upregulated in response to tumors and inflammation stimuli and is implicated in tumor growth.
