The clusters of cell types in PCa tumor microenvironment and expression of USP13 in different cell types were analyzed in scRNA-seq profiles from GSE137829 (Fig. 3A and B), GSE141445 (Fig. 3C and D), GSE143791 (Fig. 3E and F), GSE150692 (Fig. 3G and H) and GSE172301 (Fig. 3I and J). This evidence concerns the gene USP13 and neoplasm.
