Movie 9.

T cell migration and polarization is inhibited in scale explants treated with collagenase/dispase. Representative timelapse imaging of T cells in control and collagenase/dispase treated scale explants from tg(lck:GFP; lck:lifeact-ruby) showing the reduction in migration and polarization in T cells in scales treated with collagenase/dispase. Time = mm:ss. Scale bar = 20 μm.
