Thyroid follicular and parafollicular cells

WebbThe thyroid consists of two functionally distinct components: follicle cells and parafollicular cells. Follicle cells secrete the thyroid hormones, T3 and T4, and parafollicular cells secrete calcitonin. Each of these cell types has a unique embryological origin and mode of regulation. 400x.

Recently, a new group of proteins has been identified in the cells of the UBB/solid cell nests that is not present in follicular cells or parafollicular cells (C-cells) of the thyroid gland. This group of proteins is called p63, and represent homologues of p53.
