Cell deconvolution to estimate cell type abundance from spatial transcriptomic data within heterogeneous tissues


Central to spatial biology is the mapping of cell types across heterogenous tissues. This process helps us understand the relationship between cells in the context of disease and their role in response to treatment. Based on cell abundances, we identified different microenvironment cell subtypes within non-small-cell lung cancer (NSCLC) tissues and differentiated how they responded to checkpoint inhibitor therapy.

Assessment of reproducibility in multiplex immunohistochemistry


Multiplex Immunohistochemistry (mlHC) is an advanced technique that can detect tissue-based biomarkers simultaneously, which transforms the traditional approach of immunohistochemistry. mlHC enables precision medicine in both research and clinical practice because it evaluates various proteins and their spatial distribution within single tissue sections at a cellular level.  

Specific requirements are crucial for achieving high-quality staining and analysis, and to deem a mlHC assay as validated, it must be proven to be analytically reproducible.
