“…Although CD109 expression is significantly higher in lower-grade SCCs or urothelial carcinomas of the urinary bladder relative to that in higher-grade SCCs or urothelial carcinomas, respectively, 20,24,[26][27][28]40 its expression is significantly higher in higher-grade glioma, ductal carcinoma of the breast, nonsmall cell carcinomas of the lung, hepatocellular carcinoma, epithelioid sarcoma, and myxofibrosarcoma as compared with that in lower-grade tumors, respectively. 14,[16][17][18]35,41 Additionally, CD109 expression in normal tissues is strictly controlled and specifically occurs in myoepithelial cells of the mammary, lacrimal, salivary, and bronchial glands, basal cells of the prostate and bronchial epithelia and epidermis, seminiferous tubules of testis, and osteoblasts and…”
