Figure Lengend Snippet: Single‐cell RNAseq of NK cells in C57Bl/6 and KaLwRij mice after transfer of 5TGM1 cells . (A) Representative fluorescent single‐color and merged images of C57Bl/6 (top) and KaLwRij (bottom) BM. Green, GFP/5TGM1; red, NK (NKp46 + ); blue, T (CD3 + ). Arrows indicate NK cells and T cells in respective images. ×200. Scale bar = 50 μm. (B) UMAP of NK cells from C57Bl/6 and KaLwRij mice. Two animals per strain at steady state and two animals per strain at d21 after 5TGM1. Colors indicate clusters obtained at resolution 0.4. (C) Dot plot depicting average expression levels of canonical genes used to identify clusters. (D) Split UMAP of NK cells per condition. (E) Bar graph depicting cluster distribution in individual mice. Colors indicate clusters. (F) Permutation plots showing changes of NK cluster size at Day 21 relative to steady state in C57Bl/6 (left) and KaLwRij (right) ( absLog2FD > 0.58; FDR < 0.05 was considered significant) . (G) Bar graphs showing frequencies of grouped mature clusters under steady state condition and Day 21 after tumor transfer. (H) Feature plots split per condition of genes associated with NK cell cytotoxicity; circled areas refer to indicated clusters colored using respective UMAP colors. (I) Feature plots split per condition of cytokines associated with NK activity; circled areas refer to indicated clusters colored using respective UMAP colors. (J) Feature plot split per condition of Cd69 activation marker; circled areas refer to indicated clusters colored using respective UMAP colors.
