histological development of digestive tract of the persian sturgeon (acipenser persicus) from hatching to fingerling size was studied using light microscope. the digestive tract of newly hatched larvae was a simple tube which continued from mouth to anus. in 7 days post hatching, digestive tract became differentiated and secretion was started smoothly, with appearance of goblet cells in epithel...

Histological development of digestive tract of the Caspian salmon, Salmo trutta caspius, from hatching to 6 month post-hatching was studied using light microscope. The digestive tract of newly hatched larvae was a simple, undifferentiated tube which continued from mouth to anus. In 10 days post hatching larvae, the alimentary canal became more differentiated and secretion was started activity, ...

To reveal differentiation potency of yolk-sac endoderm, this tissue from quail embryos was cultured alone or in association with digestive-tract mesenchymes of chick embryos. When yolk-sac endoderm was cultured alone in vitro, the endoderm of the area vitellina differentiated into the yolk-sac parenchyma, but the endoderm of the extraembryonic area pellucida (EEAP) failed to differentiate into ...

Quail allantoic endoderm was implanted into the presumptive digestive-tract area of chick embryos, and the differentiation of the endoderm was examined morphologically and immunocytochemically with antisera against pepsinogens and sucrase. The allantoic endoderm was incorporated into the host digestive organs. It often became continuous with the host endoderm and formed a chimaeric digestive-tr...

The aim of the present work is clarifying the ontogeny of the Egyptian Sole digestive system during its larval stage (0DAH, day after hatching) until it become a juvenile (40DAH). The main changes in the morphological digestive tract was detected during its early life at 2DAH (both the mouth and anus are opened). Another day after, the digestive tract of S. vulgaris became longer. After metamor...
