Abstract: Echinodermatas are the second largest family of deuterostomes in the ocean after chordate. Coelomic cells are an important part of the immune defense of echinodermatas, and possess phagocytic encapsulation, oxidative killing, wound repair and agglutination, which play crucial functions in immune responses. This paper summarized the classifications, functions and origins of echinodermatas′ coelomocytes, such as starfish, sea urchins and sea cucumbers, in order to provide references for the cellular immune defense mechanisms of echinodermatas.

Key words: echinoderm, coelomocyte, classification, function, origin

摘要： 棘皮动物是在脊索动物后分布在海洋中的第二大后口动物。体腔细胞是棘皮动物机体免疫防御的重要组成部分，发挥着重要的免疫防御作用，具有吞噬包裹、氧化杀灭、创伤修复和凝集等多种防御功能。从体腔细胞类型、功能和发生来源3个方面综述了海星、海胆和海参3种主要棘皮动物的体腔细胞研究进展，以期为棘皮动物体腔细胞免疫防御机制研究提供参考。
