The glycosaminoglycans of normal and hyperplastic prostate.

A study has been made of the glycosaminoglycans (GAG) of the fetus, normal adult, and benign hyperplastic prostate. In the adult normal prostate dermatan sulphate (DS) is the predominant GAG. The central zone has a slightly higher chondroitin sulphate (Ch AC) content than the peripheral zone. Fetal prostates (22-27 weeks gestation) contain no heparan sulphate (HS). Benign prostatic hyperplasia (BPH) has an increased content of Ch AC. On separation of BPH stroma and epithelium, the epithelial fraction contains only Ch AC and DS. HS and hyaluronic acid (HA) are confined to the prostatic stroma.
