本文对秀丽隐杆线虫(Caelophabditis eleganshas)生殖系统的生长发育进行了形态学研究。当第一阶段的幼虫从卵中孵化出来时,它含有四个原始性腺细胞。这些细胞在25°C下45小时内增殖并形成整个成人生殖系统,由约2500个细胞核组成。在复合显微镜下可识别的性腺发生和早期胚胎发生的几个独特的形态学特征可用于绘制线虫的发育。成熟的性腺在卵母细胞的形成、受精和胚胎发生的早期阶段的时间和形态上都呈现线性发育轴。成体卵巢的结构表明,每个新形成的卵母细胞的细胞质来自多核卵巢内的共同的细胞质核心。
A morphological study of the growth and the development of the reproductive system of the nematodeCaenorhabditis eleganshas been carried out. When the first stage larva hatches from the egg it contains four primordial gonadial cells. These cells proliferate and form the entire adult reproductive system, consisting of approximately 2500 nuclei, in 45 hr at 25°C. Several distinctive morphological featues of gonadogenesis and early embryogenesis that are recognizable in the compound microscope can be used to chart the development of the nematode. The mature gonad presents a linear developmental axis both temporally and morphologically of the formation of oocytes, fertilization, and the early stages of embryogenesis. The structure of the adult ovary indicates that the cytoplasm of each newly formed oocyte is derived from a common core of cytoplasm within the multinuclear ovary.
