This paper concerns the differentiation process of germ cells from oogonia to primary follicles in the lizard Podarcis sicula. The study was carried out at the morphological level and using a cytophotometric analysis for determining the number of differentiating germ cells undergoing degeneration. The progressive disorganization of the germ cell clusters during the early diplotene stage and the role played by the prefollicular cells during this process are described. Oocyte degeneration has been observed between the mid-zygotene and the early diplotene stages. When the primary follicle (oocyte plus follicular cells) is being formed, the degeneration process stops and the oocyte undergoes regular growth and ovulation.
本文关注意大利壁蜥生殖细胞从卵原细胞到初级卵泡的分化过程。该研究在形态学水平上进行，并采用细胞光度分析来确定正在发生退化的分化生殖细胞数量。描述了双线期早期生殖细胞簇的逐渐解体以及卵泡前体细胞在此过程中所起的作用。在合线期中期和双线期早期之间观察到卵母细胞退化。当初级卵泡（卵母细胞加卵泡细胞）形成时，退化过程停止，卵母细胞进行正常生长和排卵。
