Figure 6. Knockdown of DDR1 increases junctional instability by increasing actin stress fibres.

Mock and Sh-DDR1 cells were cultured on chamber slides for 24 h and then treated (a) without or with cytochalasin D ((b) 5 nM), and ((c) 20 nM) for 4 h. Immunostaining was applied to visualise E-cadherin (green), F-actin (red), and nuclei (blue) with specific antibodies. Bar: 10 μm.
