Macrophages are immune cells that function mechanically. They play a critical role in various physiological processes, such as defending against pathogens and aiding in tissue repair. Understanding their mechanical behavior is essential for comprehending their functionality, but this aspect remains poorly explored, particularly regarding different subtypes of macrophages. Accordingly, Creative Biolabs has successfully delivered a single-cell mechanical characterization service for macrophages to elucidate their mechanical properties for a more comprehensive understanding of their functions.
While molecular profiling provides valuable insights into signaling and phenotypic changes of macrophages, recent advances in mechanobiology have revealed that cellular mechanics, such as stiffness, elasticity, and deformability, can also serve as powerful biomarkers of macrophage function and activation state.
Conventional phenotyping methods are limited in their ability to detect early or subtle functional changes in macrophages. Mechanical characteristics, however, provide label-free, non-destructive, and quantitative readouts that correlate with cytoskeletal remodeling, differentiation states, and environmental responsiveness.
Tab. 1 Why mechanical phenotyping matters?
Feature | Conventional Phenotyping | Mechanical Phenotyping |
---|---|---|
Detects surface markers | √ | × |
Measures biophysical traits | × | √ |
Captures early activation | Moderate | High |
Label-free | × | √ |
Resolution | Population-based | Single-cell |
These unique attributes make mechanical profiling especially suitable for studying macrophage polarization (M1/M2 states), disease-related transitions, and drug-induced biomechanical effects.
At Creative Biolabs, we offer a cutting-edge single-cell mechanical characterization service of macrophages. These mechanical phenotypes allow researchers to study macrophage heterogeneity, polarization, immune activation, and interaction with tumor or fibrotic microenvironments at an unprecedented resolution.
Importantly, we provide a series of single-cell mechanical characterization methods respectively targeting different locations of macrophages: cell surface, intracellular, and whole cell. Noteworthy, we also deliver a combination of different single-cell mechanical characterization methods to analyze the subpopulation of macrophages. With our robust macrophage therapeutic development platforms, we are confident in presenting comparably comprehensive mechanical properties analysis of macrophages to aid in discovering novel biomarkers on macrophages.
Here we list several methods for single-cell mechanical characterization of macrophages to choose from for your meaningful macrophage projects:
Our service is tailored for researchers in immunology, oncology, regenerative medicine, and pharmacology who aim to:
Through advanced technological means, we are able to precisely measure the stiffness, elasticity and other biomechanical parameters of individual macrophages. Against this backdrop, we are very pleased to introduce a range of products targeting macrophages. These products include macrophages as well as assay kits to support macrophage research and functional analysis. These products are rigorously tested to ensure that they can help you obtain accurate and reliable results in your research.

Macrophages remodel their mechanics during differentiation toward different subtypes and drastically adapt their shapes during phagocytosis or entry to inflamed tissues. Although these functions depend on cell mechanical properties, the mechanical behavior of macrophages is still poorly understood and accurate physiologically relevant data on basic mechanical properties of different macrophage subtypes are lacking almost entirely. By combining several complementary single-cell force spectroscopy techniques, whole cell mechanics of M1 and M2 macrophages is systematically analyzed, and it is revealed that M2 macrophages exhibit solid-like behavior, whereas M1 macrophages behave more fluid-like.

Q: What types of samples do you accept for this service? Can we send in pre-isolated macrophages or whole blood?
A: We accept various sample types to meet your research needs. You may submit pre-isolated macrophages (from PBMCs, tissue digests, or cell lines like THP-1), polarized macrophages (e.g., LPS-treated M1 or IL-4-treated M2) and PBMCs for in-house differentiation. We also offer in-house macrophage isolation, stimulation, and polarization as part of our extended service package.
Q: Is this analysis destructive to the cells? Can I recover cells for downstream applications?
A: That depends on the method selected:
Q: Can you combine mechanical profiling with other functional assays like cytokine release or phagocytosis?
A: Absolutely. We offer integrated services that can link single-cell mechanics with functional outputs. For example:
Q: What is the turnaround time?
A: The turnaround time depends on the number of conditions and complexity of the analysis. Expedited services are available upon request.
