Purpose of the Study:

• To review the applications of LCM in molecular profiling for disease research.
• To highlight LCM's role in cancer research, including mutation detection and gene expression profiling.
• To discuss LCM platforms, technical considerations, and clinical implications.

Main Methods:

• Review of existing literature on LCM applications.
• Focus on DNA, RNA, and protein analysis in specific cell types using LCM.
• Discussion of tissue preparation, analytical yields, and tissue selection for LCM.

Main Results:

• LCM facilitates the collation of genetic, epigenetic, and gene expression differences between normal and diseased cells.
• Extensive use of LCM in cancer research has advanced the understanding of tumor biology.
• LCM-based analyses support cancer diagnosis, clinical management, and targeted therapy development.

Conclusions:

• LCM is a powerful tool for molecular profiling, offering high selectivity for specific cell populations.
• Its applications significantly enhance the diagnosis and management of various human diseases, particularly cancer.
• LCM holds promise for advancing genomic studies and personalized medicine through targeted therapies.
