Research Overview

HGH (Human Growth Hormone / Somatropin) is a 191-amino-acid recombinant polypeptide hormone identical in sequence to endogenous pituitary growth hormone. It binds the growth hormone receptor (GHR) on target tissues, primarily hepatic, activating JAK2/STAT5 signaling that stimulates hepatic and peripheral production of insulin-like growth factor 1 (IGF-1). It is widely used in research models examining somatotropic axis regulation, body composition, cellular growth and metabolic signaling.

Primary Research Areas

• GH receptor (GHR) and JAK2/STAT5 signaling pathway research

• IGF-1 axis regulation and hepatic/peripheral production studies

• Body composition, lean mass and lipolysis research

• Tissue repair, cellular growth and regenerative medicine models
