Taking into account that inhibition of ILK, the enzyme that transmits signals upon integrin stimulation [13], in both PMCs and PFBs reduced cell adhesion, one may theorize that the MAs-driven adhesion of cancer cells to PFBs occurs via the α5β1 integrin-ILK axis, whereas their improved binding to PMCs involves ILK and receptors other than α5β1 integrins. Here, ILK is linked to cancer.
