THY1 and prostate neoplasm: Samples were additionally analyzed for dual expression of THY1 and ASPN. The percentage of ASPN+THY1+ cells was lower than ASPN−THY1+ cells in the stroma adjacent to benign prostate (p = 0.04); however, it was the lower‐abundance ASPN+THY1+ cells that were enriched in the cribriform prostate tumor microenvironment.
