CD44 expression in benign and neoplastic human prostates

CD44, a major cell surface receptor for hyaluronic acid, is a family of ubiquitous cell surface glycoproteins. Altered levels of CD44 expression, seen in many epithelial neoplasms, have prognostic implications. Expression of standard and variant isoforms of CD44 was assessed in normal and neoplastic human prostate tissue and culture cells to evaluate as a marker for malignant transformation.
