A SIMPLI (Single-cell Identification from MultiPLexed Images) approach for spatially resolved tissue phenotyping at single-cell resolution

Abstract: Multiplexed imaging technologies enable to study biological tissues at single-cell resolution while preserving spatial information. Currently, the analysis of these data is technology-specific and requires multiple tools, restricting the scalability and reproducibility of results. Here we present SIMPLI (Single-cell Identification from MultiPlexed Images), a novel, technology-agnostic software that unifies all steps of multiplexed imaging data analysis. After processing raw images, SIMPLI performs a spatially … Show more

“…IMC data analysis was done with SIMPLI. 8 Positive areas for combinations of markers were quantified and normalized over the tissue area or the area of selected immune populations. After segmentation, cell identities were assigned according to the highest overlap with marker-specific masks.…”

“…IMC data was generated for sixteen samples of non-cancerous colon mucosa were obtained from six individuals who underwent surgical resection of colorectal cancers (see Supplementary Information for full experimental details). The imaging data was originally published as part of (Bortolomeazzi et al 2022), but now we have additionally made available the processed single-cell data set (Märtens et al 2022). Gamma-delta T cells were expected to constitute less than 10% of T cells in human colon mucosa (Viney, MacDonald, and Spencer 1990), and their characteristic feature is that they are CD3-positive but both CD4-negative and CD8-negative.…”
