Normal thyroid gland showing the expression of thyroglobulin (TG) positive cells. Thyroglobulin is expressed in epithelial cells that outline follicles containing colloid.

Thyroglobulin (TG) - Marker for normal thyroid and thyroid cancer

Thyroglobulin is a protein exclusively produced by follicular cells in the thyroid gland, where it functions to produce the T3 and T4 thyroid hormones. Thyroglobulin is mainly used as a tumor marker for certain thyroid cancers in serum, and to monitor recurrence and/or the effectiveness of treatment against thyroid cancer.
