This video demonstrates a technique to quantify the relative ratio of macrophages among the total infiltrated immune cell populations in temporal artery biopsy. The immunohistochemical staining of a tissue section affected by autoimmune disease selectively stains the immune cells with specific receptors to visually differentiate them from the rest of the cells.

The article describes a readily easy adaptive in vitro model to investigate macrophage polarization. In the presence of GM-CSF/M-CSF, hematopoietic stem/progenitor cells from the bone marrow are directed into monocytic differentiation, followed by M1 or M2 stimulation. The activation status can be tracked by changes in cell surface antigens, gene expression and cell signaling pathways.

A protocol is presented for cell culture of macrophage colony-stimulating factor (M-CSF) differentiated human monocyte-derived macrophages. The protocol utilizes cryopreservation of monocytes coupled with their bulk differentiation into macrophages. Then harvested macrophages can then be seeded into culture wells at required cell densities for carrying out experiments.

Macrophages play a central role in homeostasis and pathology in many tissues. The protocol presented here describes methods for depleting macrophages in vivo, deriving polarized macrophages from bone marrow aspirates, and adoptively transferring macrophages into mice. These techniques allow determination of the role that polarized macrophages play in health and disease.

Macrophages have long been recognized as a critical component of the innate and adaptive immune responses. The recent explosion of knowledge pertaining to evolutionary, genetic, and biochemical aspects of the interaction between macrophages and microbes has renewed scientific attention to macrophages. This article describes a method to differentiate macrophages from mouse bone marrow.
FAQs
CD68 is associated with lysosomes, which participate in processing material taken into phagosomes. After a macrophage internalizes microbes, damaged material, or immune complexes, phagosomes fuse with lysosomes and their enzymes promote degradation. CD68 staining can therefore identify cells with prominent lysosomal compartments, but it does not directly measure how efficiently those cells ingest or destroy infectious material.
The marker reflects lysosome-rich macrophage-lineage cells rather than one defined functional program. Cells with different inflammatory roles may show CD68, so a positive signal cannot by itself establish whether macrophages are activated in a particular direction. Additional markers are needed when the research question concerns phenotype, immune function, or distinctions among macrophage populations in infected tissue.
The location and extent of staining provide spatial information about macrophage presence and cellular infiltration. A broader or denser signal may indicate that more CD68-positive cells occupy a tissue region, while distribution can show where these cells accumulate during infection or inflammation. Interpretation should remain comparative, because staining alone does not establish a specific activation state or function.
CD68 provides macrophage-lineage evidence but is not sufficient for every cell-identification question. Researchers interpret it alongside additional markers selected to distinguish macrophage phenotypes or related myeloid populations. Combining signals helps connect cell distribution with immune function and reduces the risk of treating all CD68-positive cells as functionally identical, particularly in complex inflammatory or infected tissues.
Immunohistochemistry and immunofluorescence are used to visualize CD68 in tissue sections. These approaches allow investigators to examine where the cells occur and compare staining patterns across specimens. The resulting images can support assessment of macrophage infiltration in infection and inflammation, provided that researchers interpret the signal with relevant additional markers and consistent comparisons among samples.
Mapping becomes useful when investigators need to compare macrophage distribution or infiltration across tissue sections, animal models, or clinical specimens. The approach can reveal how cellular presence differs among experimental conditions or disease-associated samples. In immunology and infection research, pairing these spatial observations with other markers helps relate macrophage localization to broader inflammatory responses without equating location alone with immune activity.
