UMAP expression plots showed Krt5 and Krt8 expression selectively in basal and luminal epithelial cell clusters of both PIN and PCa samples while hARtg and mGFP expression was mainly revealed within the BE2 cluster in PIN, and LE1-3 clusters in PCa samples (Fig. 2n). Here, KRT8 is linked to prostate intraepithelial neoplasia.
