Cancer‐associated fibroblasts–derived exosomes‐mediated transfer of LINC00355 regulates bladder cancer cell proliferation and invasion

The aim of this study was to investigate the regulatory mechanism of cancer‐associated fibroblasts (CAFs) exosome in bladder cancer (BC) cell proliferation and invasion. CAFs and normal fibroblasts (NFs) were isolated from tumor tissues and adjacent normal tissues of BC patients, and examined by immunocytochemistry for the expression of fibroblast activation protein alpha (FAP) and α‐smooth muscle actin (α‐SMA). Exosomes were extracted from CAFs...
