Cells and tissues form the bewildering diversity of crustacean larval organ systems which are necessary for these organisms to autonomously survive in the plankton. For the developmental biologist, decapod crustaceans provide the fascinating opportunity to analyse how the adult organism unfolds from organ Anlagen compressed into a miniature larva in the sub-millimetre range. This publication is the second part of our survey of methods to study organogenesis in decapod crustacean larvae. In a companion paper, we have already described the techniques for culturing larvae in the laboratory and dissecting and chemically fixing their tissues for histological analyses. Here, we review various classical and more modern imaging techniques suitable for analyses of eidonomy, anatomy, and morphogenetic changes within decapod larval development, and protocols including many tips and tricks for successful research are provided. The methods cover reflected-light-based methods, autofluorescence-based imaging, scanning electron microscopy, usage of specific fluorescence markers, classical histology (paraffin, semithin and ultrathin sectioning combined with light and electron microscopy), X-ray microscopy (µCT), immunohistochemistry and usage of in vivo markers. For each method, we report our personal experience and give estimations of the method’s research possibilities, the effort needed, costs and provide an outlook for future directions of research.

研究十足目甲壳动物幼虫器官发生的方法 II:分析细胞和组织

细胞和组织形成了甲壳类幼虫器官系统的令人眼花缭乱的多样性,这是这些生物体在浮游生物中自主生存所必需的。对于发育生物学家来说,十足目甲壳类动物提供了一个迷人的机会来分析成年生物体如何从器官原素中展开,并压缩成亚毫米范围内的微型幼虫。本出版物是我们研究十足目甲壳动物幼虫器官发生方法调查的第二部分。在一篇配套论文中,我们已经描述了在实验室培养幼虫以及解剖和化学固定其组织以进行组织学分析的技术。在这里,我们回顾了各种经典的和更现代的成像技术,这些技术适用于分析十足目幼虫发育过程中的行为学、解剖学和形态发生变化,和协议,包括许多成功研究的技巧和窍门。这些方法包括基于反射光的方法、基于自体荧光的成像、扫描电子显微镜、特定荧光标记的使用、经典组织学(石蜡、半薄和超薄切片结合光学和电子显微镜)、X 射线显微镜 (μCT)、免疫组织化学和体内标志物的使用。对于每种方法,我们都会报告我们的个人经验,并对该方法的研究可能性、所需的努力、成本进行估计,并提供对未来研究方向的展望。经典组织学(石蜡、半薄和超薄切片结合光学和电子显微镜)、X 射线显微镜 (μCT)、免疫组织化学和体内标记物的使用。对于每种方法,我们都会报告我们的个人经验,并对该方法的研究可能性、所需的努力、成本进行估计,并提供对未来研究方向的展望。经典组织学(石蜡、半薄和超薄切片结合光学和电子显微镜)、X 射线显微镜 (μCT)、免疫组织化学和体内标记物的使用。对于每种方法,我们都会报告我们的个人经验,并对该方法的研究可能性、所需的努力、成本进行估计,并提供对未来研究方向的展望。
