In situ hybridization visualizes RNA in cells, but image analysis is complex. We present a protocol based on open-source software for automated high-content multiplex fluorescence in situ transcriptomics analysis. Steps include nuclei segmentation with a Fiji macro and quantification of up to 14 mRNA probes per image. We describe procedures for storing raw data, quality control images, and the use of a Python app to summarize all the results in one spreadsheet detailing the number of single or co-positive cells.
原位杂交可使细胞中的RNA可视化,但图像分析很复杂。我们提出了一种基于开源软件的方案,用于自动化的高内涵多重荧光原位转录组学分析。步骤包括使用Fiji宏进行细胞核分割,以及对每张图像中多达14种mRNA探针进行定量分析。我们描述了存储原始数据、质量控制图像的程序,以及使用Python应用程序在一个电子表格中汇总所有结果的方法,该表格详细列出了单个或共阳性细胞的数量。
