TL;DR
From the known interactions of adhesion molecules, the results suggest that CD44, and beta 1 and beta 3 integrins may be important in tumour/mesothelial interactions.
Abstract
A major route for the spread of ovarian cancer is by the attachment of tumour cells to the mesothelium lining in the peritoneal cavity. The expression of various adhesion molecules has been measured on freshly-prepared mesothelial cells, two mesothelial cells lines and 13 established ovarian tumour cell lines. The integrins beta 1 and beta 3, ICAM-1, and CD44 were detected on all mesothelial preparations and on many or all of the tumour lines. VCAM-I was expressed exclusively on the mesothelial cells and Lewis x was expressed on half of the tumour lines. There was low or no expression of sialyl Le(x), sialyl Le(a), integrins alpha 4, beta 1, beta 4, or E and P selectins. Only CD44 expression was significantly affected by trypsin treatment. From the known interactions of adhesion molecules, the results suggest that CD44, and beta 1 and beta 3 integrins may be important in tumour/mesothelial interactions.

The major obstacle in making any sweeping generalizations about cell adhesion molecules and tumor progression, however, is that the process of successful metastasis is inherently complex, requiring tumor cells to possess decreased adhesive interactions with surrounding cells and extracellular matrix at some points in the cascade and increased adhesive interactions at other times.

Analysis of CD44 splice variants may prove to have applications not just to the early detection of metastatic potential in surgical biopsy specimens but also, if the findings are confirmed, in readily available bodily fluids to theearly diagnosis of cancer in screening programmes, to the assessment of remaining disease in the body and to theEarly detection of recurrences.

The results suggest that the apparent inability of ascitic OVCAR‐3 cells to attach to host‐tissue surfaces may be a consequence, in part, of low levels of expression of laminin, type IV collagen and/or typeIV collagenase.
