Laser capture microdissection

Area of Science:

• Biotechnology
• Molecular Biology
• Genomics

Background:

• The tissue microenvironment is a complex ecosystem studied at multiple resolution levels.
• Spatial molecular interrogation tools are essential for understanding tissue complexity.

Purpose of the Study:

• To highlight Laser capture microdissection (LCM) as a foundational technology for spatial molecular analysis.
• To discuss LCM's applications in understanding tissue heterogeneity and disease mechanisms.
• To explore the future of LCM in personalized medicine.

Main Methods:

• LCM enables downstream acquisition and analysis of nucleic acids, proteins, metabolites, and lipids.
• LCM preserves spatial context for multiomic profiling.

Main Results:

• LCM provides spatially resolved analysis of tissue heterogeneity and microenvironment interactions.
• LCM is a versatile platform, agnostic to tissue type, molecular target, and analytical tool.
• LCM is a key component in large-scale clinical trials for revealing disease mechanisms.

Conclusions:

• LCM is a powerful tool for spatially resolved multiomic profiling.
• LCM advances the understanding of disease mechanisms and therapeutic efficacy.
• Next-generation LCM technologies will drive personalized and designer therapies.
