Abstract

The integument acts as a barrier to protect the body from harmful pathogenic infectious agents, parasites, UV rays, trauma, and germs. The integument of invertebrates and vertebrates are structurally different: while invertebrates usually have a simple monolayer epidermis frequently covered by mucus, cuticles, or mineralized structures, vertebrates possess a multilayered epidermis with several specialized cells. This study aims to describe by morphological, histological, and immunohistochemical analyses, the morpho-structural adaptations throughout evolution of the integument of gastropod Aplysia depilans (Gmelin, 1791), ascidian Styela plicata (Lesuer, 1823), myxine hagfish Eptatretus cirrhatus (Forster, 1801) and teleost Heteropneustes fossilis (Bloch, 1794) for the first time, with special reference to sensory epidermal cells. Different types of cells could be identified that varied according to the species; including mucous cells, serous glandular cells, clavate cells, club cells, thread cells, and support cells. In all integuments of the specimens analyzed, sensory solitary cells were identified in the epidermis, immunoreactive to serotonin and calbindin. Our study provided an essential comparison of integuments, adding new information about sensory epidermal cells phylogenetic conservation and on the structural changes that invertebrates and vertebrates have undergone during evolution.

不同水生生物被膜形态结构的适应性

表皮起到保护身体免受有害病原体、寄生虫、紫外线、创伤和细菌侵害的屏障作用。无脊椎动物和脊椎动物的表皮在结构上不同：无脊椎动物通常有一个简单的单层表皮，经常被粘液、角质层或矿化结构覆盖，而脊椎动物则有一个带有几个特殊细胞的多层表皮。本研究旨在通过形态学、组织学和免疫组织化学分析，首次描述腹足类Aplysia desplans（Gmelin，1791）、海鞘Styela plicata（Lesuer，1823）、myxine hagfish Eptatretus cirrhtus（Forster，1801）和硬骨鱼异呼吸化石（Bloch，1794）在整个表皮进化过程中的形态结构适应，特别涉及感觉表皮细胞。可以鉴定出不同类型的细胞，这些细胞因物种而异；包括粘液细胞、浆液腺细胞、棒状细胞、棒细胞、线细胞和支持细胞。在分析的所有标本的表皮中，在表皮中发现了感觉孤立细胞，对血清素和钙结合蛋白呈免疫反应。我们的研究对表皮进行了重要的比较，增加了关于感觉表皮细胞系统发育保护以及无脊椎动物和脊椎动物在进化过程中经历的结构变化的新信息。

期刊介绍： Acta histochemica, a journal of structural biochemistry of cells and tissues, publishes original research articles, short communications, reviews, letters to the editor, meeting reports and abstracts of meetings. The aim of the journal is to provide a forum for the cytochemical and histochemical research community in the life sciences, including cell biology, biotechnology, neurobiology, immunobiology, pathology, pharmacology, botany, zoology and environmental and toxicological research. The journal focuses on new developments in cytochemistry and histochemistry and their applications. Manuscripts reporting on studies of living cells and tissues are particularly welcome. Understanding the complexity of cells and tissues, i.e. their biocomplexity and biodiversity, is a major goal of the journal and reports on this topic are especially encouraged. Original research articles, short communications and reviews that report on new developments in cytochemistry and histochemistry are welcomed, especially when molecular biology is combined with the use of advanced microscopical techniques including image analysis and cytometry. Letters to the editor should comment or interpret previously published articles in the journal to trigger scientific discussions. Meeting reports are considered to be very important publications in the journal because they are excellent opportunities to present state-of-the-art overviews of fields in research where the developments are fast and hard to follow. Authors of meeting reports should consult the editors before writing a report. The editorial policy of the editors and the editorial board is rapid publication. Once a manuscript is received by one of the editors, an editorial decision about acceptance, revision or rejection will be taken within a month. It is the aim of the publishers to have a manuscript published within three months after the manuscript has been accepted
