超薄切片介绍

对样本开展研究时，为了以纳米级分辨率显示其精细结构，通常会使用到电子显微镜。电子显微镜有两种类型：扫描电子显微镜（SEM）用于对样本表面成像，以及需要使用极薄电子透明样本的透射电子显微镜（TEM）。因此，使用电子显微镜对样本内部的精细结构进行成像时，此类技术解决方案需要制作出非常薄的样本切片。被称为超显微技术的样本制备方法可以产生具有最小伪影的超薄切片（厚度20-150nm）。在切片过程中，样本的…

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
