CTLs (bead-stimulated primary human CD8+ T cells) were stained with Hoechst 33342 (blue) and then embedded in collagen matrix (2 mg/ml). Cell migration was visualized using Cell Observer (20X objective) at 37oC with an interval of 30 sec. The migration trajectories were tracked with Imaris8.1.2. The trajectory of the preceding and the succeeding cell are in red and purple, respectively. Time stamp is HH:MM:SS. Scale bar is 7 microns. Credit Sadjadi et al.
