Single-cell RNAseq analysis of coronavirus receptors in human and murine bladder and prostate. UMAP-based dimensionality reduction plot denoting cell types (A, C, E, G) and corresponding expression levels of ACE2, DPP4, ANPEP and TMPRSS2 (B, D, F, H) from multiple studies: (A–B) human bladder (Yu et al., 2019), (C–D) murine bladder from Tabula Muris (Tabula Muris Consortium et al., 2018), (E–F) murine bladder from Mouse Cell Atlas (Han et al., 2018), and (G–H) human prostate and prostatic urethra.
