摘要

两栖动物在脊椎动物进化中占有重要地位。此外,两栖动物被认为是羊膜动物和羊膜动物之间的过渡群体。然而,关于羊膜动物,特别是无尾动物配子发生的研究很少。因此,本研究的目的是分析Levantine frog Pelophylax bedriagae (Camerano, 1882)睾丸中生殖细胞的组织学特征及其排列。生精细胞在精囊内组织。每个精囊中都含有处于生精周期同一阶段的细胞。根据细胞的大小、形态和核物质的压实程度对精小管中各细胞类型进行鉴定。精原细胞是位于精原上皮底部的大细胞。初生精母细胞在第一次减数分裂的不同阶段被检测,其与其他细胞类型的区别在于其深色球形核或松散的染色质。精子细胞分为球形细胞和细长细胞两种。精小管被管周肌样细胞包围,不含管腔。精子小管中缺乏管腔和囊性精子发生可能提供了大量精子的同步产生。透明质酸的位置也被确定在精小管之间的间质组织中,可能是为了保证睾丸的完整性和粘弹性。

Characterization of testicular histology and spermatogenesis in the Levantine frog, Pelophylax bedriagae (Amphibia: Anura: Ranidae)
Amphibians occupy a position of great interest in terms of vertebrate evolution. Additionally, amphibians are known as a transitional group between amniotes and anamniotes. However, there are few studies on the gametogenesis of anamniotes vertebrates, especially anurans. Therefore, the purpose of this study was to analyze the histological feature of germ cells and their arrangement in the testis of Levantine frog, Pelophylax bedriagae (Camerano, 1882). Spermatogenic cells were organized in spermatocysts. Each spermatocyst contained cells at the same stage of the spermatogenic cycle. Identification of each cellular type in seminiferous tubule was carried out according to the size and morphology of cells and the degree of nuclear material compaction. Spermatogonia were large cells localized at the base of the seminiferous epithelium. Primary spermatocytes were examined in different phases of first meiotic division and distinguished from other cell types by their dark spherical nuclei or looser chromatin. Two types of spermatids, spherical and elongated cells, were observed. Seminiferous tubules were surrounded by peritubular myoid cells, and they contained no lumen. The lack of lumen in the seminiferous tubules and the cystic spermatogenesis probably provide synchronously production of a large number of sperms. The location of hyaluronic acid was also determined in interstitial tissue between seminiferous tubules to probably provide testicular integrity and viscoelasticity.

期刊介绍: Annales de Limnologie - International Journal of Limnology publishes papers on the ecology of freshwater systems, ranging from studies of aquatic organisms, physical and chemical works which relate to the biological environment, to ecological applications and frameworks for water management directives. Main topics: Ecology of freshwater systems ; biodiversity, taxonomy, distribution patterns in space and time, biology of animals and plants ; experimental and conceptual studies which integrate laboratory and/or field work on physiology, population dynamics, biogeochemistry and nutrient dynamics, management, mathematical modelling ; techniques for sampling and chemical analyses, ecological applications, procedures which provide frameworks for environmental legislation.
