Altered inflammatory mucosal signatures within their spatial and cellular context during active ileal Crohn's disease.

Crohn's disease (CD) involves a complex intestinal microenvironment driven by chronic inflammation. While single-cell RNA sequencing has provided valuable insights into this biology, the spatial context is lost during single-cell preparation of mucosal biopsies. To deepen our understanding of the distinct inflammatory signatures of CD and overcome the limitations of single-cell RNA sequencing, we combined spatial transcriptomics of frozen CD surgical tissue sections with single-cell transcriptomics of ileal CD mucosa.

Hierarchical marker genes selection in scRNA-seq analysis.

When analyzing scRNA-seq data containing heterogeneous cell populations, an important task is to select informative marker genes to distinguish various cell clusters and annotate the clusters with biologically meaningful cell types. In existing analysis methods and pipelines, marker genes are typically identified using a one-vs-all strategy, examining differential expression between one cell cluster versus the combination of all other cell clusters. However, this strategy applied to cell clusters belonging to closely related cell types often generates overlapping marker genes, which capture the common signature of closely related cell clusters but provide limited information for distinguishing them.
