There has never been a study of the components of germ cells as they progress through spermatogenesis.
The structural changes taking place in rat germ cells, from spermatogonia to late spermatids, were studied utilizing morphometric techniques conducted largely at the ultrastructural level.
Volume and surface area parameters for virtually all cellular and subcellular features were obtained for nine periods during the spermatogenic cycle. Virtually all germ cell components show dynamic properties associated with specific phases of their development.
The data provided can be used in an objective way to characterize structural changes taking place during spermatogenesis and to relate those structural changes to functional properties of germ cells.
从未有过关于生殖细胞在精子发生过程中各成分变化的研究。
利用主要在超微结构水平进行的形态计量学技术，研究了大鼠生殖细胞从精原细胞到晚期精子细胞发生的结构变化。
在精子发生周期的九个阶段，获取了几乎所有细胞和亚细胞特征的体积和表面积参数。几乎所有生殖细胞成分都表现出与其发育特定阶段相关的动态特性。
所提供的数据可用于客观地描述精子发生过程中发生的结构变化，并将这些结构变化与生殖细胞的功能特性联系起来。
