In the application notes of the Neo-Source MSI DPI, pathological diagnosis is explicitly listed as a key area, covering disease biomarker discovery, early disease diagnosis, clinical pathology research, bacterial analysis, microbial imaging, determining tumor grade, hormone-receptor status, gene-chip detection, cell biology and microbial ecology. MSI provides molecular-species and coordinate information that can be registered with histological means such as H&E and IHC.
Its engineering advantages fit the pathology scenario: matrix-free, low ion suppression, tissue can be analyzed directly; 20–200 μm adjustable resolution; the section remains intact after imaging for continued H&E pathological testing, making the research chain of 'imaging first, staining validation later' smooth.
Determining tumor grade and judging hormone-receptor status are key steps in pathological diagnosis. By comparing molecular spectral differences between tumor and paratumor regions, MSI can identify molecules specifically enriched or absent as potential grading and receptor-related biomarkers. In a published DPI case, the melanocytic nevus region and normal tissue showed systematic differences in lipid spectral patterns, and the characteristic molecule distribution highly matched the H&E nevus region, exactly reflecting this approach.
It must be emphasized that MSI is mostly at the research and translation stage; entering formal diagnosis still requires standardization, cohort validation and regulatory approval; it already has clear value in 'assisting biomarker discovery', 'explaining mechanisms' and 'complementing existing diagnosis'.
The DPI application notes also include bacterial analysis, microbial imaging and microbial ecology as pathology-related directions. For infection- or microbiota-related samples, MSI can distinguish different microorganisms or their metabolic features in-situ in tissue, assisting understanding of infection distribution and microecological structure, providing a molecular spatial perspective for infectious pathology research.
Matrix-free preparation makes such often diverse and complex sample-preparation scenarios easier to deploy: the two Neo-Source imaging sources are matrix-free and measure on demand, allowing pathology and testing personnel without MSI expertise to begin using them relatively quickly.
MSI is not to replace the microscope or IHC, but to complement. In practice, MSI sections are often registered with adjacent H&E/IHC sections, overlaying molecular signals onto histological structures to form dual 'morphology + molecule' interpretation.
Engineered to be compatible with mainstream mass spectrometers from Agilent, AB SCIEX and Thermo, the two Neo-Source imaging sources provide a self-developed titanium-alloy ion transfer tube that does not damage the sample at the front end and is detachable for cleaning, supporting stable and reproducible pathology-related imaging research.
