The dual expression of Vimentin and αSMA observed within tumour‐associated stromal cultures, indicative of a myofibroblast‐like phenotype, is consistent with the stromal alterations seen in vivo and the accumulation of myofibroblasts (vimentin+ αSMA+) within the prostate interstitium (Tuxhorn et al., 2002). Here, ACTA1 is linked to neoplasm.
