Cells could be detected on the surface of the matrix, adhering directly to the matrix (figure 5b).
Since basement membranes of glomerular vessels contain a small amount of fibronectin compared with collagen and laminin (Yurchenco and Schittny, 1990) as well as general basement membranes, CHO cells with α5 β1 might have difficulty in adhering directly to fibronectin in basement membranes of glomeruli during metastasis.

Interestingly, mES cells do not adhere directly to the gelatin substrate, but rather adhere indirectly through gelatin-bound fibronectin, which facilitates self-renewal via its effects on cell adhesion.
In the case of bacteria, if the phagocyte cannot adhere directly, protein components of the blood known as opsonins (e.g., complement and antibodies) form a surface film on bacteria a process known as opsonization.
Electron microscopy also shows that these cells have no basement membrane – suggesting that they adhere directly to the underlying collagen bundles – and that, while one side of a given collagen bundle is lined by these cells, the opposite side is usually unlined and directly exposed to fluid in the space.
The chorion acted as a strong protective barrier and prevented passage, even though SWCNT adhered directly to it [89].
Some cysts may adhere directly to the tendon sheath (Fig. 5) or may be located within the tendon [6, 10].
