A novel method to obtain macrophages from primary culture of rat liver cells is described. This method utilizes the proliferation of macrophages in the culture, followed by shaking of culture flasks and purification by selective attachment to plastic dishes. This technique efficiently provides liver macrophages without complex equipment and skills.

This video demonstrates an enzyme-free protocol to isolate macrophages from mouse dorsal root ganglion (DRG) using a mechanical dissociation technique. Upon homogenization of the freshly collected DRG tissue, antibodies against the cell-surface receptors on the macrophages are used to label the cells fluorescently, followed by performing flow cytometry to confirm the presence of macrophages in the sample.

Here, we study hepatotoxicity caused by lapatinib and neratinib through SASP-driven macrophage polarization, which offers a deeper mechanistic understanding beyond traditional toxicity tests. This approach demonstrates how senescent hepatocytes influence immune responses. This is particularly valuable for assessing long-term drug effects and discovering new therapeutic targets for managing drug-induced hepatotoxicity.

Source: Zhang, C. et al. Development and Assessment of Intracellular Infection Models for Staphylococcus aureus. J. Vis. Exp. (2025)This video demonstrates the quantification of intracellular survival of a methicillin-resistant bacterial pathogen in mouse peritoneal macrophages. It outlines the steps involved in infection, extracellular bacterial clearance, host cell lysis, and colony enumeration to assess bacterial survival within host macrophages.
FAQs
The key comparison is origin and recruitment. Resident Kupffer cells are established liver macrophages, whereas monocyte-derived macrophages enter the liver from recruited monocytes. Examining these populations separately can reveal whether an observed response reflects surveillance by resident cells or an inflammation-associated influx, an important distinction in infection and tissue injury studies.
Pattern-recognition receptors detect microbial signals or molecules released from damaged tissue. This recognition can initiate phagocytosis, cytokine production, and antigen presentation, linking detection to both immediate defense and communication with other immune cells. In mouse liver research, comparing these responses helps clarify how macrophages distinguish infection-related challenges from tissue-derived inflammatory signals.
Macrophage activity is shaped by communication with hepatocytes and lymphocytes, not only by direct exposure to pathogens or debris. These interactions influence whether inflammation is coordinated with tissue protection or becomes harmful. Studying this cellular context helps explain how the liver maintains antimicrobial defense while preserving tissue tolerance during immune activation.
Macrophage phenotypes provide a way to relate cellular state to disease context. Resident and recruited populations may participate differently during infection, inflammation, or fibrosis, so treating all liver macrophages as one uniform group can obscure relevant biology. Characterizing phenotype alongside recruitment and activation supports more precise interpretation of tissue responses and experimental outcomes.
A study can focus on debris removal, recognition of microbial or tissue-derived signals, phagocytosis, cytokine production, or antigen presentation. It can also assess interactions with hepatocytes and lymphocytes. Together, these observations show how macrophages respond to a challenge and how their activity may influence antimicrobial defense, inflammation, or tissue injury.
They are useful when researchers need to connect liver immune activity with infection, inflammation, fibrosis, or altered macrophage recruitment and activation. Their responses provide a framework for examining pathogen surveillance, tissue damage, and immune coordination. This makes them relevant for evaluating how changes in macrophage behavior could influence disease mechanisms or therapeutic strategies.
