Application of laser capture microdissection to capture pure cells in lung cancer and their paired normal lung tissues / 西安交通大学学报(医学版)

ABSTRACT

Objective Microheterogeneity is an important problem in molecularly biological and proteomic research on malignancies.The goal of this study was to investigate the method to purify targeted cells in lung cancer and its paired normal tissues for proteomic study on lung cancer applying laser capture microdissection(LCM).Methods LCM technique was emploged to obtain the cells of lung cancer tissues and their paired normal tissues from frozen sections.Results LCM can be applied to quickly and precisely obtain pure targeted cells subgroup or single cell without interstitium under the microscope.Conclusion LCM can tackle the problem of tissue heterogeneity in molecular analysis successfully.These results indicate that LCM has a potential as a tool in lung cancer proteomic research.
