本文用光镜、透射电子显微镜和扫描电子显微镜技术，从外部形态和内部解剖组织的发育两个方面，研究了地中海海鞘臂部的再生。根据不同结构发育的时间和方式及其相互作用，可以将整个手臂的形态发生分为三个主要阶段：1)体腔依赖阶段，2)神经系统依赖阶段，3)骨骼依赖阶段。此外，用组织荧光和免疫组织化学方法显示儿茶酚胺和吲哚胺，可以揭示多巴胺和5-羟色胺的存在，并跟踪这些神经递质在再生过程中的波动和不同的参与。
The regeneration of the arm of the crinoidAntedon mediterraneahas been studied by means of LM, TEM, and SEM techniques as regards the development of both the external form and the internal anatomical organization. According to the timing and the modalities of development of the different structures and their reciprocal interactions, three main stages can be recognized in the morphogenesis of the whole arm: 1) a coelom-dependent stage, 2) a nervous system-dependent stage and 3) a skeleton-dependent stage. Moreover, using histofluorescence and immunohistochemical methods to visualize catecholamines and indolamines, it has been possible to reveal the presence of dopamine and serotonin and follow the fluctuations and the different involvements of these neuro-trasmitters during the regeneration process.
