摘要
本文研究了从鱼类到哺乳类七种脊椎动物肝细胞,探索了不同动物肝细胞及同种动物不同发育时期肝细胞的大小、核的大小、细胞体积、核的体积、核质指数相应的变化。这种变化反映了细胞的形态和机能矛盾的统一是生物进化的原因之一。
We studied the hepatocytes of seven vertebrates from fish to mammal in this paper. We also examined the size of hepatocytes and its nuclear size in different animals and different stage of the same animals, the relationship among cell, nuclear volume and nucleo-plasmic ratio. It shows that the coincidence of morphology and function is the main reason of biological evolution.
