顶体的 meaning in English
acrosomal
acrosomic
Examples
- Nucleoli do not emerge in this process . the number of the organelles increase until secondary spermatocyte stage . mitochondria accumulate together , merging together with lysosomes and golgi bodies at the early spermatid stage , and finally the lamellar structure is formed , which forms the acrosome at last
在精子发生过程中，线粒体、内质网和核糖体逐渐增多，其中线粒体数目在次级精母细胞阶段达到顶峰，并形成线粒体区，精细胞早期核内出现膜性泡结构，同时次级溶酶体与高尔基体大量存在，这些细胞器共同形成片层复合体，并参与顶体的形成。 - Fertilization is a highly programmed process by which two radically different cells , sperm and egg , unite to form a zygol it is mediated by complementary molecules present on the surface of the respective gametes . especially the proteins in the sperm acrom play an important role , but only a little can be extracted from sperm . now large amount of proteins can be obtained easily using biological technique
受精是配子间相互作用最后融合成合子的过程，是由配子各自表面蛋白分子互补介导的，特别是存在于精子顶体的蛋白，但从精子中提取量少，用分子生物学手段大量克隆表达所需蛋白为受精机理的研究提供了方便。 - Nucleoli exist from spermatocyte stage to early spermatid stage . in this process , the numbers of ribosomes , mitochondrions and endoplasmic reticulums increase until secondary spermatocyte stage , golgi apparatus emerges at the secondary spermatocyte stage , and then , these organelles change into lamellar complex which finally forms the acrosome
核糖体，线粒体和内质网等细胞器数量逐渐增多，到次级精母细胞阶段达到最大，在形成精子的过程中，上述细胞器与高尔基体及膜性泡共同分化或参与形成片层小体，并参与顶体的形成。
