Detection of Calcitonin Cells in Camel (Camelus dromedarius) Parathyroid Glands
(Saeed Y. Al-Ramadan, Mohammad A. Alzayer, Abdelhadi M. Ali, Thnian A. Althnian, Ibrahim F.Albokhadaim, and Ramadan O. Ramadan)Abstract
Both thyroid and parathyroid glands are derivatives of the pharyngeal pouches. During early embryological stages,
calcitonin cells (C-cells) migrate from neural crest to the fourth pharyngeal pouch before they are incorporated
within thyroid gland and become an integral postnatal component of this gland. This study was conducted to
investigate the presence of C-cells in the parathyroid glands of adult dromedary camels. Ten parathyroid glands
from adult camels of both sexes were investigated using immunohistochemical technique. Calcitonin cells were
markedly detected as several cells groups within the internal parathyroid glands, whereas few cells were reacted
to the anti-calcitonin antibody within the external parathyroid glands. In conclusion, the C-cells could be found in
derivatives of fourth pharyngeal pouches other than thyroid gland like the internal parathyroid glands.
Key Words: Camel, C-Cell, Parathyroid glands, Pharyngeal pouched.
