PTK2 and benign prostatic hyperplasia: To further explore the interplay between cellular traction force and BPH‐induced fibrotic bladder, immunofluorescence was performed to co‐localize cellular traction force‐related markers such as p‐FAK and p‐NMIIA with the fibroblast activation markers such as alpha smooth muscle Actin (α‐SMA) and Col1 in fibroblast marked by FSP1, and this observation led us to consider a positive correlation between cellular traction force and FMT in BPH bladder development (Figure 1L).
