LCM-seq: A method for spatial transcriptomic profiling using laser capture microdissection coupled with PolyA-based RNA sequencing

Abstract

LCM-seq couples laser capture microdissection of cells from frozen tissues with polyA-based RNA sequencing and is applicable to single neurons. The method utilizes off-the-shelf reagents and direct lysis of the cells without RNA purification, making it a simple and relatively cheap method with high reproducibility and sensitivity compared to previous methods. The advantage with LCM-seq is also that tissue sections are kept intact and thus the positional information of each cell is preserved.
