| 摘 要： | 采用形态观察与连续组织切片技术,观察和研究了哲罗鱼（Hucho tai men）肝脏和胰脏在胚胎期（水温7～8℃）和胚后期（水温3～14℃）的发育。结果表明,与大多数硬骨鱼类不同,哲罗鱼的肝脏是在破膜前就开始发生、发育,而胰脏是在破膜后出现,以后逐渐发育完善。受精18 d肝原基细胞出现,破膜8 d,胰细胞出现,破膜8 ...

Histological ontogenesis of liver and pancreas in taimen Hucho taimen |

| Abstract: | The histological and morphological ontogenesis of liver and pancreas in taimen Hucho taimen was studied by serial section technique.The results showed that there are significant differences in the taimen from most of the teleost in that the liver ontogenesis initiated before hatching in the taimen and the pancreas ontogenesis was appeared after hatching.The liver primodium was observed 18 days after fertilization,and the pancreatic cells were found 8 d after hatching,and the liver cells to have fat storing 18 days after hatching,indicating that the liver development is involved in yolk absorption.The liver and pancreas are independent organs,and have prolific tubes. |
