Immunohistochemical study of cyst structures in chick ultimobranchial glands. 1984

Y Kameda

In order to clarify the functional significance of cyst structures located in ultimobranchial glands, chick ultimobranchial glands of various ages were investigated by an immunoperoxidase method using anti-calcitonin, anti-somatostatin and anti-19S-thyroglobulin antisera. At hatching, the cysts were consistent features of the chick ultimobranchial glands. With aging, they gradually increased in volume and number. In adult chickens, a major portion of ultimobranchial glands was occupied by cysts of various sizes, shapes and luminal contents. Some cyst epithelium consisted of calcitonin-positive cells alone, and a portion of the cystic contents was intensely immunoreactive to the calcitonin antiserum. Neither cyst epithelium nor luminal contents were stained with the 19S-thyroglobulin or the somatostatin antiserum. The present study indicates that some cyst structures of chick ultimobranchial glands are related to the synthesis, secretion and accumulation of calcitonin.

UI MeSH Term Description Entries
D002116 Calcitonin A peptide hormone that lowers calcium concentration in the blood. In humans, it is released by thyroid cells and acts to decrease the formation and absorptive activity of osteoclasts. Its role in regulating plasma calcium is much greater in children and in certain diseases than in normal adults.

D002645 Chickens Common name for the species Gallus gallus, the domestic fowl, in the family Phasianidae, order GALLIFORMES. It is descended from the red jungle fowl of SOUTHEAST ASIA. Gallus gallus,Gallus domesticus,Gallus gallus domesticus,Chicken
D000367 Age Factors Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013004 Somatostatin A 14-amino acid peptide named for its ability to inhibit pituitary GROWTH HORMONE release, also called somatotropin release-inhibiting factor. It is expressed in the central and peripheral nervous systems, the gut, and other organs. SRIF can also inhibit the release of THYROID-STIMULATING HORMONE; PROLACTIN; INSULIN; and GLUCAGON besides acting as a neurotransmitter and neuromodulator. In a number of species including humans, there is an additional form of somatostatin, SRIF-28 with a 14-amino acid extension at the N-terminal.

D013954 Thyroglobulin
D014460 Ultimobranchial Body A diverticulum from the fourth pharyngeal pouch of an embryo, regarded by some as a rudimentary fifth pharyngeal pouch and by others as a lateral thyroid primordium. The ultimobranchial bodies of lower vertebrates contain large amounts of calcitonin. In mammals the bodies fuse with the thyroid gland and are thought to develop into the parafollicular cells.
