Cluster of Differentiation 44 (CD44) is a glycoprotein receptor for hyaluronic acid that plays a fundamental role in cellular adhesion, stromal binding, migration, and cell-cell interactions. Positive staining with Anti-CD44 is implicated in a multitude of different cancer types, including breast, prostatic, renal cell, colonic, hepatocellular, and genitourinary carcinomas, as well as non-Hodgkin's Lymphoma, metastatic melanoma, gastric cancer, and some soft tissue tumours. It has also been demonstrated that there is a positive correlation between tumour progression and increased expression of CD44v, a high molecular weight CD44 isoform that has been described in epithelial cells. Given the expression of CD44 in a wide range of cancers, the most practical application of CD44 immunostaining is its use in discriminating between urothelial transitional cell carcinoma in situ from non-neoplastic changes in the urothelium.
