CD44 is a family of cell-surface glycoproteins that are expressed in a variety of human solid tumours, particularly those of gynaecological origin (e.g., ovarian cancers) (Naor et al, 1997; Kayastha et al, 1999), and is implicated in cell adhesion, motility and metastases (Naor et al, 1997). This evidence concerns the gene CD44 and ovarian carcinoma.
