Indeed, the comprehensive application of PDGFRA, FAP, Vimentin, and ACTA2 for discerning fibroblast subsets in the PCa microenvironment successfully distinguished fibroblasts not only from the adjacent tissue but also from HSPC patients exhibiting lower expression levels of PDGFRA, FAP, Vimentin, and α‐SMA. Here, VIM is linked to posterior cortical atrophy.
