Natural killer (NK) cells have been suggested to play a major role in resistance against metastatic spread of tumors. This study was aimed at understanding whether laminin (LM), a component of the extracellular matrix involved in the mechanism of tumor invasion and cell interaction, is expressed by NK cells. The results indicate that NK cells can synthesize and display on the cell surface LM and that TPA can modulate its expression. Our findings suggest that the presence of LM on NK cells could be relevant in the control of tumor invasion by NK cells.
