Assays of transendothelial migration in vitro

Area of Science:

• Immunology
• Cell Biology
• Physiology

Background:

• The inflammatory response is vital for healing and fighting pathogens, but uncontrolled inflammation underlies many diseases.
• Leukocyte recruitment and their migration across endothelium are key events in inflammation, often considered irreversible.
• Understanding leukocyte transendothelial migration is crucial for studying inflammatory processes.

Purpose of the Study:

• To describe established in vitro assays for studying leukocyte transendothelial migration.
• To provide reliable and reproducible methods for observing this critical cellular process.
• To validate these assays for predicting in vivo inflammatory responses.

Main Methods:

• Detailed description of in vitro transendothelial migration assays.
• Utilizing controlled laboratory conditions for observing leukocyte-endothelial cell interactions.
• Comparison of in vitro assay results with in vivo inflammation models.

Main Results:

• The described in vitro assays have been used successfully for decades.
• These methods demonstrate reproducibility, reliability, and predictive value.
• The assays accurately reflect leukocyte and endothelial cell behavior in inflammatory conditions in vivo.

Conclusions:

• In vitro transendothelial migration assays are powerful tools for dissecting inflammatory mechanisms.
• These assays offer a controlled environment to study leukocyte trafficking.
• The described methods are validated for their predictive relevance to in vivo inflammation.
