Abstract

ZHANG, Hui et al. Micro-ultrastructure Features of Liver in Chinese Taihe Black-bone Silky Fowl (Gallus gallus domesticus Brisson). Int. J. Morphol. [online]. 2014, vol.32, n.3, pp.1015-1021. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022014000300043.

In this work, the morphological features of liver in Chinese Taihe black-bone silky Fowl (BSF) were analyzed by light microscope and transmission electron microscopy. The results showed that two kinds of hepatocytes were present in Taihe BSF liver, i.e., the dark and the light hepatocyte. The dark hepatocyte was electron-dense and lager, with many organelles, mitochondria especially. The light hepatocytes were smaller than the dark. They had electron-lucent cytoplasm with a small number of organelles. Furthermore, there were lipolysosomes in the light hepatocyte. The numerous long and serried finger-like microvilli spread into bile canaliculus lumen. The glycogen granules intensely stained, spread in some hepatocytes. Numerous glycogen granules scattered in cytoplasm especially near bile canaliculi. However, lipid droplets were not observed in any hepatocytes. The natural apoptotic hepatocytes were observed in Taihe BSF liver. The hepatocytes which contain abundant uesicae-like endoplasmic reticulum closed the apoptotic hepatocytes and spread the process to approach the cell residual bodies. Besides, there was a macrophage with several phagosomes. In conclusion, the dark and the light hepatocyte were present in Chinese Taihe BSF liver. They were different from electron-dense and organelles. The hepatocytes of Taihe BSF could undergo natural apoptosis, regeneration and renew ability.
