The thymus rudiment of the chick develops from the posterior wall of the 3rd and 4th pharyngeal pouches at the 4th day of incubation. The thymus is divided into lobules by the mesenchym at 9th day. Thymus corpuscles appear about the 13th day. Cortex and medullary of the thymus begin to differentiate at 15th days. Model thymus corpuscle consists of many reticulocyte until the 21st day. The dorsal and ventral pancreatic buds appear about the 3rd to 4th day. Exeretive portion of the pancreas is compcund tubul gland on the early stage, but after 15 days of incubation it changesinto cmopound tbunloal veolar gland. Pancreatic islets appear at the 11th day. To follow embryonic growth, the amount of pancreatic islet increase gradually. The genital ridges develop at the 3rd days of incubation During 4 days of incubation the primordial sex cells come from yolk—sac entoderm and migrate toward left gonad in the female. Primary sex cords extend to medullary and to form interstitial cells. Secondary cords form follicle cells. In the male at the 5th day, ihe primary sex cord extend to mesenchym to form the rudiment of convoluted seminiferous tubule and interstitial cells. The sex of the gonad is distinguishable after 8 days of incubation.

在孵化的第4d,鸡胚胸腺的原基发生于第Ⅲ、Ⅵ咽囊的背壁上皮。到第9d,胸腺被间充质分叶。胸腺小体发生于第13d。在第15d,胸腺的皮质与髓质开始分化。到20~21d,在封闭的微血管周围,由数层网状细胞形成典型的胸腺小体。背侧胰芽及腹侧胰芽发生于孵化的第3~4d。到第15d,外分泌部由初期的复管状腺变成复管泡状腺。胰岛细胞团在第11d发生。随着鸡胚的发育,胰岛的数目逐渐增多。生殖嵴在第3d发生。到第4d,从卵黄囊内胚层来的原性细胞,便向雌性左侧的性腺转移。初级性索仲入髓质形成间质细胞。次级性索形成卵泡细胞。第5d时,雄性的初级性索,仲入间充质内形成曲细精管及间质细胞群的原基。第8d以后,性腺的性别可以区分。
