Abstract
Every tissue contains heterogeneous cell populations. Laser capture microdissection (LCM) facilitates cell isolation from complex tissues followed by molecular analysis. LCM entails placing a transparent film over a tissue section or a cytological sample, visualizing the cells microscopically, and selectively adhering the cells of interest to the film with a focused pulse from an infrared laser (6). The film with the procured cells of interest to the film with a focused pulse from an infrared directly into DNA, RNA, or protein-extraction buffer for processing. LCM has revolutionized molecular analysis of complex tissues because it combines the topographic precision of microscopy with the power of molecular genetics, genomics, and proteomics. However, the success of molecular analysis still depends on the experimental design and requires the understanding of each technical step involved in specimen preparation. This review attempts to rationalize and demystify the choice of various technical options in upstream tissue processing supporting global analytical strategies.Keywords
