Article Title: Spatially visualized single-cell pathology of highly multiplexed protein profiles in health and disease
doi: 10.1038/s42003-021-02166-2
Figure Lengend Snippet: a Tissue samples were obtained from healthy and diseased tonsils (chronic tonsillitis) in 5-µm-thick formalin-fixed, paraffin-embedded samples. b The thin tissue sections were then stained with metal-conjugated antibodies and get ablated from the tissue’s surface through the argon plasma and analyzed by the time of flight mass spectrometer. c Individual marker images can be assembled and visualized using different colors to observe the marker’s coexpression and spatial organization. d Cells were segmented using CellProfiler software for single-cell quantification. e Single-cell analyses provide the marker expression distributions, including phenotype clustering based on the coexpression of markers. Phenographs of all normal and diseased ROIs show the different phenotypes that make up the sample to n = 25–27 groups. Immune and stromal markers were selected to cluster the entire dataset of the normal and diseased tonsil. The markers list includes CD20, CD68, CD3, CD4, CD8a, granzyme B, pankeratin, and E-cadherin.

Article Snippet: After a series of optimizations, cellular segmentation masks and single-cell protein expression data were generated using the Cellprofiler (4.0.7) data analysis pipeline as recommended by Fluidigm.
