N-cadherin Junction Formation Leads to Cell-Matrix Adhesion Disassembly near the Contact
(A) Outline and direction of migration of colliding cell pair, either in the absence or presence of N-cadherin (N-cadh) BA. Cells expressing membrane RFP (red) and GFP-FAK (green).
(B) Total area of GFP-FAK labeled CMAs at the contact during a collision. 0 min: first frame of contact, n = 3 collisions for both conditions.
(C) Control and N-cadherin BA treated cells expressing membrane RFP (gray) and GFP-FAK color coded for longevity.
(D) Longevity of CMAs near contact of cells expressing GFP-FAK. n = 30 for each condition.
(E) Total area of FAK labeled CMAs near the contact. n = 28 cells for both conditions.
(F and G) (F) Cells in clusters; zoom of region of contact shown by immunocytochemistry against p-paxillin in control cells (n = 171) cells expressing N-cadherin morpholino (n = 89) or treated with N-cadherin blocking antibody (n = 68). p-paxillin (green), phalloidin (red), Hoescht (blue). P-paxillin alone in left zoom colored according to fluorescence intensity (G). Total area of p-paxillin labeled CMAs at the contact. n = 68 cells.
