Flow Cytometry Assessment of Lymphocyte Populations Infiltrating Liver Tumors

Area of Science:

• Immunology
• Oncology
• Biotechnology

Background:

• Immune cells are crucial for liver cancer immunosurveillance and response to immunotherapy.
• Hepatocellular carcinoma and cholangiocarcinoma treatments benefit from understanding immune cell populations.
• High-dimensional cytometry is key for characterizing immune cells in pre-neoplastic and neoplastic liver lesions.

Approach:

• Presents a multicolor immunofluorescence staining and flow cytometry protocol for hepatic lymphocyte analysis.
• Details viability assessment and immune cell phenotyping using surface and intracellular staining for numerous markers.
• Includes a fixative-resistant viability dye for streamlined cell fixation, permeabilization, and staining.

Key Points:

• Protocol allows parallel processing of multiple samples without prior debris removal.
• Enables detailed assessment of lymphocyte subtype and differentiation state in liver tissues.
• Provides an adaptable antibody panel for characterizing lymphocytic subsets in various experimental contexts.

Conclusions:

• The protocol facilitates in-depth characterization of immune cell populations in liver neoplasia.
• Supports advancements in understanding liver cancer immunosurveillance and immunotherapy.
• Offers a robust method for flow cytometry-based immune cell analysis in hepatic research.
