Which of the following cell type(s) secretes prostate specific antigen (PSA)?
Correct Answer: Benign and malignant prostate epithelial cells
Description: Prostate-specific antigen (PSA), a glycoprotein with a MW of 34,000, is a biological marker used in the detection of prostate cancer. It is secreted from prostatic epithelial cells and is responsible for aiding liquefaction of semen. This marker, which is evaluated with a blood test, can be produced by both benign and malignant epithelial cells. The prostate stromal cells do not produce PSA.
