| Ultrastructural changes in Sparus macrocephalus cells during spermatogenesis |
|
|
| Abstract: |
| This paper discussed morphological and structural changes of cell during spermatogenesis of Sparus macrocephalus by transmission electron microscopy. The characteristics of fine structure of spermatogenesis cells and sperms in various orders are described in detail. The result indicated that the nucleus form and the concentration of chromatin, the numbers, the distribution position and the ultrastructure of mitochondria changed during spermatogenesis. In addition, the secretion of Golgi body and morphological differentiation of lysosome were reported. |
