模式生物研究

模式生物是研究人员用来研究特定生物学过程的物种。它们具有与人类相似的遗传特征，通常用于遗传学、发育生物学和神经科学等研究领域。选择模式生物的原因通常是它们在实验室环境中易于保持和繁殖、生成周期短，或能够产生突变体来研究某些性状或疾病。

Overcoming Challenges with Microscopy when Imaging Moving Zebrafish Larvae

Zebrafish is a valuable model organism with many beneficial traits. However, imaging a full organism poses challenges as it is not stationary. Here, this case study shows how zebrafish larvae can be…

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

激光微切割（LMD）促进的分子生物学分析

使用激光微切割（LMD）提取生物分子、蛋白质、核酸、脂质和染色体，以及提取和操作细胞和组织，可以深入了解基因和蛋白质的功能。它在神经生物学、免疫学、发育生物学、细胞生物学和法医学等多个领域有广泛应用，例如癌症和疾病研究、基因改造、分子病理学和生物学。LMD 也有助于研究蛋白质功能、分子机制及其在转导途径中的相互作用。

利用激光显微切割（LMD）在空间背景下分离神经元

在阿尔茨海默病之后，帕金森病是第二常见的进行性神经退行性疾病。在首发症状出现之前，中脑中高达70%的多巴胺释放神经元已经死亡。本文描述了如何使用现代激光显微切割（LMD）方法帮助解决帕金森病之谜。研究涉及在空间背景下分离和分析神经元。这些细胞来自帕金森病患者的死后黑质组织样本，以便深入了解该病的分子机制。
