活细胞成像指南

在生命科学各研究领域的广泛应用中，活细胞成像是一种不可或缺的工具，用于观察细胞在尽可能接近活体（即活的、活跃的）状态下的情况。本指南回顾了确保成功进行活细胞成像的各种重要注意事项，并介绍了各种旨在克服常见挑战的高性能解决方案。这些进展使我们能够对细胞生理学和动力学有新的认识。

利用光片显微技术聚焦三维长时程成像

长时程三维成像揭示了复杂的多细胞系统是如何生长和发育的，以及细胞是如何随着时间的推移而移动和相互作用的，从而揭示了发育、疾病和再生方面的重要知识。光片显微镜一次只照射样品的一个薄片，大大减少了光损伤，保护了样品的活性。这种温和的高速技术可在数小时甚至数天内提供清晰的体数据，使研究人员能够实时捕捉生物学的发展过程。

来捕捉发育动态的3D成像

本应用说明展示了研究人员如何成功利用 Viventis Deep 双视角光片显微镜探索3D多细胞模型（包括有机体、球形体和胚胎）的高分辨率长期成像，从而为发育生物学和疾病研究带来新的可能性。

Developing embryos of different species at different stages during the elongation of their posterior body axis, from left to right in developmental time. The labelled regions in red depict a region of undifferentiated cells called the tailbud, with the corresponding region generated from that tissue shaded in grey. Upper row: lamprey; middle row: catshark; bottom row, zebrafish. This figure has been adapted from the following publication: Steventon, B., Duarte, F., Lagadec, R., Mazan, S., Nicolas, J.-F., & Hirsinger, E. (2016). Species tailoured contribution of volumetric growth and tissue convergence to posterior body elongation in vertebrates. Development, 2016. 143(10):1732-41
