Malassezia-Induced Skin Inflammation and Fungal Burden Analysis in a Murine Model

2025
This video demonstrates Malassezia-induced skin infection in mice. Malassezia oil suspension is applied over the wounded ear, triggering inflammation and swelling of the ear tissue. Later, the ears are dissected, homogenized, and spread on an agar plate for growth. The number of colonies indicates the fungal burden resulting from skin inflammation.
FAQs
The two steps address different barriers within skin tissue. Mincing and mechanical disruption physically break tissue into smaller fragments, while controlled enzymatic digestion helps separate cells from the extracellular matrix. Combining them improves access to both resident and infiltrating populations, but the process must remain controlled because excessive disruption can reduce viability or damage surface markers needed for downstream immune-cell analysis.
Cell-surface markers allow researchers to distinguish immune populations and characterize their activation or recruitment. Murine Skin Dissociation therefore aims to release cells without substantially compromising viability or marker accessibility. If processing damages these features, flow-cytometry measurements, cell sorting decisions, and comparisons between experimental groups may become less reliable, particularly in studies of inflammation or pathogen-associated responses.
A well-controlled suspension makes both resident cells and cells recruited during inflammation accessible for analysis, enabling researchers to examine changes in population composition. In infection or skin-disease models, those changes may reflect immune-cell recruitment, tissue inflammation, or pathogen-associated responses. Consistent processing is essential because differences caused by dissociation could otherwise be mistaken for biological differences between samples.
The workflow begins with tissue mincing, followed by controlled enzymatic digestion and mechanical disruption to release cells from the tissue matrix. The resulting suspension can then be prepared for downstream analysis, including flow cytometry, cell sorting, culture, or molecular assays. Maintaining a consistent sequence and level of processing helps produce comparable suspensions across samples and experimental conditions.
The resulting single-cell suspension supports several complementary approaches. Flow cytometry can characterize cellular populations, while cell sorting can isolate selected populations for further study. Researchers can also place the cells in culture or use them in molecular assays. Together, these options allow analysis of immune composition, inflammatory responses, pathogen-associated changes, and tissue-repair processes.
It is particularly useful when investigators need to examine how skin immune populations change during inflammation, infection, or tissue repair. Access to resident and infiltrating cells enables comparisons of cellular recruitment and pathogen-associated responses within disease models. Standardized dissociation also strengthens comparisons among experimental groups, helping distinguish treatment- or disease-related effects from variation introduced during sample preparation.
