Fig. 2.

The expression levels of specific marker genes of diverse luminal clusters examined by scRNA-seq analysis and immunostaining in PCa tissue. a Violin plots displaying the expression levels of each luminal representative markers in each cluster. b Expression levels of representative markers for each luminal cluster plotted onto the UMAP. Color key from gray to red indicates relative expression levels from low to high. c Immunostaining showing the cytological localization of each luminal cluster cells in representative PCa tissues. Blue fluorescence represents nucleus stained with DAPI; green fluorescence represents type 1 luminal cells stained with anti-SLC45A3; red fluorescence represents type 2 luminal cells stained with anti-CP; purple fluorescence represents type 3 luminal cells stained with anti-B4GALT1
