Prostate epithelial cell. Coloured scanning electron micrograph (SEM). Shed prostate epithelial cell from a urine sample of a patient with acute prostatitis. The prostate is a small gland found only in men. It's about the size of a walnut and gets a little bigger with age.The prostate produces a thick, white fluid that mixes with the sperm produced by the testicles to make semen. It also produces a protein called prostate-specific antigen (PSA) that turns the semen into liquid. The pseudostratified columnar epithelium is covered in microvilli (small hair-like projections).
