NCIt definition : A recombinant form of the heterodimeric human anterior pituitary glycoprotein thyroid-stimulating
hormone (TSH) with potential use in hormone replacement therapy. Recombinant TSH binds
to TSH receptors on thyroid epithelial cells and stimulates TSH-dependent signaling
pathways. This stimulates iodine uptake and organification, and induces synthesis
and secretion of thyroglobulin (Tg), triiodothyronine (T3), and thyroxine (T4).;
