Calcitonincontaining
Calcitonin-containing is a term used to describe cells or tissues that produce calcitonin, a hormone primarily known for its role in calcium homeostasis. Calcitonin is secreted by the parafollicular cells of the thyroid gland, specifically the C-cells. Its primary function is to lower blood calcium levels by inhibiting bone resorption and enhancing calcium excretion by the kidneys. Calcitonin-containing cells are found in the thyroid gland and, in some species, in other tissues such as the skin and gut. The hormone is also produced by certain types of cancer cells, particularly medullary thyroid carcinoma, which can lead to elevated calcitonin levels in the blood. The measurement of calcitonin levels in blood tests is a useful diagnostic tool in the evaluation of thyroid disorders and certain types of cancer. The term "calcitonin-containing" is often used in scientific literature and medical contexts to refer to these cells or tissues.
