Abstract

Introduction: The morphogenic and histogenetic events of an organ and their time sequencingare basic required information to study factors involved in cells differentiation and evaluating theinfluence of different agents during the critical period of organ formation. The birds are noted asmodels in experimental Embryologic studies, more than other animals. The present study describedthe morphogenetic events of Pheasant (as a native bird of Iran) Esophagus, as a unique investigation. Methods: We analyzed the Pheasant Embryos from fifth-24th days of incubation period. Aftermeeting the routine methods of histology laboratory, the slides were stained with Hematoxylin-Eosin, Periodic Acid-Schiff, Alcian Blue, and Van Gieson staining methods. Then, the formationof four layers of primordial Esophagus, its epithelial cell differentiation, the separation of laminapropria and submucosa, time of glands formation, their secretion activities and the shape of lumenof gland were studied by a light microscope. Results: The data of this study indicated that the most esophageal developmental events of thepheasant occur in the first 2-thirds of the incubation period. The esophageal primordium was notedfor the first time on the fifth day of incubation period. The mesenchymal boundary of the Esophaguswas distinguishable during seventh to eighth days of incubation period. They differentiated thelamina propria and muscular layers during the next 10 days. The epithelial layer of Esophagus wasgradually differentiated from pseudostratified columnar epithelium (ninth day) into the 2 layeredcuboidal (9-10), simple cuboidal (10-12), and the stratified squamous (13th day onward). Theesophageal glands were the only structures that began to form in the second half of the incubationperiod on the 15th day and completed their development on the 21th day. In the present work, themost developmental events were observed in the thoracic Esophagus earlier than cervical region. Conclusion: The comparison of the obtained data with other studied birds shows a general patternof the Esophagus formation among them. However, some differences can be detected in thedevelopmental details and in the time sequencing of the layers. Some of these variations can berelated to the differences in the duration of the incubation period among different species.
