Overview
This article describes a novel method for obtaining macrophages from primary cultures of rat liver cells. The technique involves the proliferation of macrophages in culture, followed by shaking the flasks and purifying the cells through selective attachment to plastic dishes.
Key Study Components
Area of Science
- Neuroscience
- Cell Biology
- Immunology
Background
- Isolation methods for liver macrophages have been previously described.
- Most existing methods require complex equipment and advanced skills.
- This study aims to simplify the process of obtaining liver macrophages.
