Integrin a3 and a5 are important in leading fibroblasts in SCC.
siRNA against integrin 3 or integrin 5 in stromal fibroblasts would prevent the invasion of SCC cells and Figure 4C shows that siRNA-mediated depletion of either integrin 3 or integrin 5 in stromal fibroblasts, but not in SCC cells, reduced the collective invasion of SCC cells.
Several groups have shown that integrin a5 can activate Rho signalling16, 17, 18, and this result was confirmed in carcinoma-associated fibroblasts (data not shown). Integrin a3 was also important for force-mediated matrix remodelling, but we found no evidence that it regulated Rho activity (data not shown).

In the endoplasmic reticulum, integrin subunits find their binding partners and form heterodimers.
Monomeric integrins never reach the cell surface.

During gastrulation, type 1 EMT is associated with de novo expression of a5b1, which is a receptor for fibronectin.
Type 2 EMT in experimental kidney fibrosis is associated with increased a5 integrin expression.
