Ovarian morphology was studied from the inception of meiosis in the cat, mink and ferret. It was shown that "open connections", allowing cellular contact, existed between the intra-ovarian rete cords and the groups of germ cells as well as between the surface epithelium and the germ cells. The germ cells in the innermost part of the cortex and lying in contact with the rete cells were those which were the first to enter meiotic prophase. Later, the more peripheral oogonia transformed to oocytes. The first follicular formations occurred at the innermost part of the cortex. The granulosa cell layers were in open connection with the intra-ovarian rete cords. In the mink and ferret, a certain part of the rete system at the hilus differentiated into the hilar rete body. In all animals, the extra-ovarian rete cells were actively secreting. It is proposed that the rete system interacts with the cortex, initiating the start of meiosis and that the rete cells as well as cells of the surface epithelium contribute to the granulosa cell layer.
从猫、水貂和雪貂减数分裂开始就对其卵巢形态进行了研究。结果表明，卵巢内的网索与生殖细胞群之间以及表面上皮与生殖细胞之间存在允许细胞接触的“开放连接”。皮质最内层与网细胞接触的生殖细胞是最早进入减数分裂前期的细胞。后来，更外周的卵原细胞转变为卵母细胞。最早的卵泡形成发生在皮质最内层。颗粒细胞层与卵巢内网索有开放连接。在水貂和雪貂中，门部网系统的特定部分分化为门部网体。在所有动物中，卵巢外的网细胞都在活跃分泌。有人提出，网系统与皮质相互作用，启动减数分裂的开始，并且网细胞以及表面上皮细胞对颗粒细胞层有贡献。
