UMAP-based dimensionality reduction plot denoting cell types (A, G) and corresponding expression levels of ACE2, DPP4, ANPEP and TMPRSS2 (B, H) from adult (A–B) and fetal (G–H) human kidney samples (Stewart et al., 2019). (C–F) Violin plot visualization of gene expression for ACE2 (C), TMPRSS2 (D), ANPEP (E), and DPP4 (F) in adult human kidney scRNAseq dataset. Automated literature synthesis highlights strong associations of ACE2, DPP4, and ANPEP to the kidney.
