12 早期胚胎發(fā)展階段的老鼠頭部
這張3D圖片顯示的是早期胚胎發(fā)展階段的老鼠頭部，是由高清晰反相顯微鏡拍攝的。在拍攝過程中，樣本放在塑料片上，然后涂上曙紅熒光色。這種顯微鏡薄片切片機可切割非常薄的樣本，最薄達到2微米。
使用計算機軟件，老鼠頭部的不同結(jié)構(gòu)得以成像。圖片是由英國醫(yī)學(xué)研究理事會所提供的。
This 3D image of a developing mouse head at an early embryonic stage was created using high-resolution episcopic microscopy (HREM). In HREM, samples are embedded in a plastic that has been stained with eosin, a fluorescent dye. A microtome is used to slice away fine sections of the sample – as thin as 2 microns – then an image of the remaining block is captured after each slice is taken. Using computer software, different structures within the head can be visualised. Colour channels can be added to the 3D reconstruction to highlight tissue density, as shown here.
