title: Lymphocyte locomotion III. ultrastructural studies of the lymphocyte traffic over the postcapillary venules of rat lymph nodes.
abstract: The direction of lymphocytes with amoeboid movement configuration (AMC) was evaluated by means of electron microscopy of ultrathin sections of post-capillary high-endothelium venules (HE-venules) from rat lymph nodes. Out of 104 lymphocytes, 68 lymphocytes appeared to be on their way towards the lumen of the HE-venule and 36 lymphocytes appeared to be moving away from the venular lumen at the moment of fixation. This difference, which was statistically significant (p=0.0024), is thought to reflect the relative size of the migration stream of lymphocytes at the moment of fixation.
