  • Beschreibung: <jats:p>Single-cell ribonucleic acid sequencing is becoming widely employed to study biological processes at a novel resolution depth. The ability to analyse transcriptomes of multiple heterogeneous cell types in parallel is especially valuable for cell-focused lung research where a variety of resident and recruited cells are essential for maintaining organ functionality. We compared the single-cell transcriptomes from publicly available and unpublished datasets of the lungs in six different species: human (<jats:italic>Homo sapiens</jats:italic>), African green monkey (<jats:italic>Chlorocebus sabaeus</jats:italic>), pig (<jats:italic>Sus domesticus</jats:italic>), hamster (<jats:italic>Mesocricetus auratus</jats:italic>), rat (<jats:italic>Rattus norvegicus</jats:italic>) and mouse (<jats:italic>Mus musculus</jats:italic>) by employing RNA velocity and intercellular communication based on ligand–receptor co-expression, among other techniques. Specifically, we demonstrated a workflow for interspecies data integration, applied a single unified gene nomenclature, performed cell-specific clustering and identified marker genes for each species. Overall, integrative approaches combining newly sequenced as well as publicly available datasets could help identify species-specific transcriptomic signatures in both healthy and diseased lung tissue and select appropriate models for future respiratory research.</jats:p>
