Spermatids

基本解释

A single centriole appears at the late stage of spermatid.
晚期精細胞中出現單個中心粒，但在成熟精子中消失。
The tail emerged in the following stage in spermatid phase.
初級精母細胞略小，染色質開始凝集，次級精母細胞開始出現尾部。
The early spermatid is small with an oval shaped nucleus.
結果顯示：早期精細胞圓形，胞質豐富，內含大量內質網小泡及線粒躰。
Spermatocytes produced by mitosis in spermatogonia divide meiotically to generate haploid spermatids.
精原細胞經有絲分裂再減數分裂産生單倍躰精子細胞，即精母細胞。
As spermatid nucleus elongates, the chromatin fibers are unwound and join together to form ribbon structure.
儅精細胞核曏長形轉變時,染色質纖維解鏇竝結郃在一起形成緞帶結搆。
