Spermatids

基本解释

A single centriole appears at the late stage of spermatid.
晚期精细胞中出现单个中心粒，但在成熟精子中消失。
The tail emerged in the following stage in spermatid phase.
初级精母细胞略小，染色质开始凝集，次级精母细胞开始出现尾部。
The early spermatid is small with an oval shaped nucleus.
结果显示：早期精细胞圆形，胞质丰富，内含大量内质网小泡及线粒体。
Spermatocytes produced by mitosis in spermatogonia divide meiotically to generate haploid spermatids.
精原细胞经有丝分裂再减数分裂产生单倍体精子细胞，即精母细胞。
As spermatid nucleus elongates, the chromatin fibers are unwound and join together to form ribbon structure.
当精细胞核向长形转变时,染色质纤维解旋并结合在一起形成缎带结构。
