拟染色体

Chromatoidbody（CB，拟染色体）是一个生殖细胞特异性的胞质结构。

Chromatoid body is a germ cell-specific cytoplasmic structure .

黄颡鱼除A1型精原细胞外的各期生殖细胞都存在拟染色体，并且随着细胞的不断发育拟染色体逐渐变小分散，最后在精子内完全消失。

Each germ cell had chromatoid body except for the spermatogonium of Al type , and the chromatoid body became small and dispersed with the cell developing constantly , disappearing completely in the sperm .

拟染色体的形成方式与其它鱼类中拟染色体的形成方式相似。

Its pattern was similar to that of other teleosts .

在精子细胞阶段之前的各期生精细胞中都存在拟染色体。

Chromatoid bodies existed at all stages of spermatogenic cells except in spermatids .

运用电子显微镜观察了鲫鱼生精细胞发育过程中拟染色体的形成和解体，以及拟染色体和线粒体的关系。

The formation and disintegration of chromatoid body , as well as the relationship between the chromatoid body and mitochondrion in the spermatogenesis of teleost Carassius auratus was analyzed by transmission electron microscopy .
