Figure 5.
Locomotion of transmigrating wt and DOCK2–/–T cells underneath the endothelial layer. Lymphocyte motion underneath the endothelial monolayer was tracked immediately after completing TEM. The fraction of transmigrating wt or DOCK2–/– T cells that successfully locomoted for at least 3 cell diameters on the basal substrate away from the TEM site is depicted for each population. (Inset) Tracks of 3 individual wt and DOCK2–/– T cells taken immediately after TEM completion. Black dots denote the sites of the lymphocyte TEM, and white lines denote the lymphocyte locomotion tracks after TEM underneath the endothelium. Bar = 30 μm. Results are representative of 5 independent experiments.
