FGF signaling is required for polarized migration of the middle fragment. (A,B) PLLp fragments 20 and 250min after ablation, but in the presence of 80μM SU5402. (C,D) PLLp fragment 20 and 250min after ablation, with subsequent wash-out of SU5402. Arrowhead indicates migration of trailing cells toward leading cells. Scale bar: 10μm.
