软骨鱼类输卵管腺研究进展

输卵管腺(oviductgland)是软骨鱼类特有的生殖器官,由雌性软骨鱼类的输卵管前段发育形成,输卵管腺对于软骨鱼类的生殖具有重要意义,参与了卵壳的合成,卵胶的分泌,精子储存等多个重要生命过程。同时输卵管腺的合成产物中含有一种高度交联的胶原蛋白复合材料,具有韧性强、抑菌、抗污、可降解等特点,是极具开发价值的海洋生物材料。但是目前中国该领域研究基础较为薄弱,本文通过对软骨鱼类的生殖方式、输卵管腺的结构、卵壳分泌过程等几部分的研究进展进行阐述,以期为软骨鱼类的繁育、新型生物材料的开发提供启发。

A review of the oviduct glands of cartilaginous fishes

The oviduct gland is an important reproductive organ unique to cartilaginous fishes, which develops from the anterior part of the oviduct. The oviduct gland participates in crucial life processes, such as the synthesis of the egg capsule, secretion of the egg jelly, and the storage of sperm. Secretions from the oviduct gland contain a highly crosslinked collagenous composite marine biological material that is extremely tough and possesses antibacterial, antifouling, and degradable properties. However, studies on the oviduct glands of cartilaginous fishes are relatively limited in China. Herein, we review several areas of interest concerning the oviduct glands of cartilaginous fishes, such as reproductive strategies, the structure of the oviduct gland, and the secretion processes. Further, we summarize the current challenges in oviduct gland research, such as sperm storage and oviduct gland secretion, that highlight areas for future investigation. We also hope this review provides a reference for future studies on cartilaginous fishes.
