Rigidity-dependent cross talk between integrin and cadherin signaling.


Integrin-cadherin cross talk is an important aspect of cell function. We explored this signaling using substrates micropatterned with islands of fibronectin surrounded by E-cadherin, capturing the segregation of these signals in normal tissue. While MDCK cells were able to concurrently form adhesive structures with these two proteins, engagement of fibronectin by MCF-7 cells, an adenocarcinoma cell line, inhibited response of these cells to E-cadherin. We further demonstrated that this inhibition is rigidity dependent; on soft elastomer substrates with Young's modulus in the range of tens of kiloPascals, MCF-7 cells were able to engage both integrin and cadherin ligands.
